Chair’s Chat

Journals Devoted to Solar Physics: We regret the error

Dana Longcope
17 Mar 2016

In the previous Chair’s Chat (2/15/2016) I carelessly described the journal Solar Physics as “the one journal dedicated exclusively to our field”. My statement is clearly wrong, and The Living Reviews of Solar Physics provides an obvious counter-example. It is also a journal devoted exclusively to Solar Physics. I regret the error.

JHelioviewer: A New Generation is Now Available

David Berghmans
25 Mar 2016

JHelioviewer is a well-established open-source application for visualisation of solar images based on the JPEG 2000 standard. It is part of the Helioviewer Project and it is another client to the Helioviewer web services alongside the helioviewer.org web-application. Since late 2013, the whole software stack was revisited under ESA Contract No. 4000107325/12/NL/AK commonly referred to as “Space Weather HelioViewer”. Many of the new additions will be of particular interest to the Space Weather community. The new generation of JHelioviewer is available for download from jhelioviewer.org and sidc.be/jhelioviewer

The new JHelioviewer is significantly faster and more robust while offering a large number of new functionalities, among which:

    access to new datasets (GONG,  SOLIS, etc) from 3 different servers (GSFC, ROB, IAS)

  • combined view from different vantage points (e.g. STEREO and SDO) for full sphere mapping
  • image projections such as orthographic, latitudinal and polar
  • yet more viewing options, such as running and base differences, and a side-by-side (multiview) mode
  • timeline datasets viewing, synchronized with the time of the current image
  • integration of features and events from the Heliospheric Event Knowledge database, and alerts from the COMESEP system.
  • magnetic field line extrapolations

A full description of the installation, running of the software and new features are available on the online user manual: sidc.be/jhelioviewer/

The work was carried out by SIDC @ Royal Observatory of Belgium (ROB). The new JHelioviewer will continue to undergo improvements in the future, meanwhile feedback is welcome at swhv – at – sidc.be

28 Mar 2016

The 2016 NASA Living with a Star Targeted Research and Technology (LWS TR&T) Steering Committee will soon begin developing the next round of LWS focused science topics and strategic capability topics, for ROSES 2017. It is vital for the success of the LWS TR&T program that there be active community engagement in the development of annual TR&T science topics. We are therefore asking the Heliophysics community to provide input by April 26, 2016 for these topics.

Suggested science topics should be organized around achieving the goals set out in the strategic science areas (SSA’s) articulated in the LWS Ten Year Vision (lwstrt.gsfc.nasa.gov/images/pdf/LWS_10YrVision_Oct2015_Final.pdf),

Physics-based Understanding to Enable Forecasting of:
  • SSA-0, Solar Electromagnetic, Energetic Particle, and Plasma Outputs Driving the Solar System Environment and Inputs to Earth’s Atmosphere
  • SSA-1, Geomagnetic Variability
  • SSA-2, Satellite Drag
  • SSA-3, Solar Energetic Particle
  • SSA-4, Total Electron Content
  • SSA-5, Ionospheric Scintillation
  • SSA-6, Radiation Environment

The structure of a topic should indicate a target description, the targeted SSAs, goals and measures of success, types of investigations, interactions with user communities and expected deliverables.

Hinode Solar Optical Telescope Filtergraph Anomaly

Sabrina Savage
29 Mar 2016

The Hinode Solar Optical Telescope Focal Plane Package contains three CCD cameras: Filtergraph (FG), Spectro-polarimeter (SP) and Correlation Tracker (CT). The FG camera suddenly developed an electrical short circuit on 2016 February 25, after 9.4 years of operation on-orbit, and it was promptly switched off. The other two cameras are unaffected, and science observing resumed with the SP and CT on March 3rd. The FG camera collects both broadband and narrowband images, so neither type has been available since Feb 25th. Engineers at Lockheed Martin have been studying the cause and possible recovery of the FG camera since the anomaly occurred. A similar short circuit in the CCD camera on the GOES-15 Soft X-ray Imager was recovered in 2010, with nominal operation of the instrument since then.  Recovery of the FG camera may be attempted in the next month or so, but the likelihood of success is not known. We are proceeding cautiously, since all three cameras share the same power supplies, and we do not want risk damage to the SP or CT.

In the meantime, Hinode and SOT continue a full schedule of observing, including Hinode Observing Programs (HOPs) and frequent coordination with IRIS and other observatories.  The telemetry previously used by the FG has been allocated amongst SP and the other two Hinode instruments, resulting in large increases for EIS and XRT, especially when observing targets at the limb. The added telemetry for SP enables collection of more fast time series and full-resolution maps of the photospheric vector magnetic field and other atmospheric properties. Revised observing strategies and programs using only SP are being created to support existing HOPs and new observation requests. Requests for further information or new observations can be sent to us or to the SOT Science Scheduling Coordinators, Dick Shine (shine at lmsal.com) and Takashi Sekii (sekii at solar.mtk.nao.ac.jp).

IRIS/Hinode Support for ALMA Cycle 4 Observations

Bart De Pontieu
30 Mar 2016

Coordination with ALMA observations of the Sun is high priority for both the IRIS and Hinode missions. IRIS and Hinode provide observations from the photosphere to the corona that are ideal complements to the chromospheric measurements with ALMA. During the upcoming ALMA cycle 4 solar observations from December 2016 to April 2017, IRIS and Hinode will prioritize support of successful ALMA cycle 4 solar observing proposals. Proposers to the ALMA cycle 4 can refer to this message as evidence of IRIS/Hinode support for their observations.

We suggest that PIs of accepted ALMA proposals inform the Hinode and IRIS teams as soon as possible of the desired observational support — our teams will be happy to collaborate with you to tailor the coordinated observations to your science goals. We suggest that successful ALMA proposers submit a request for an IHOP (IRIS-Hinode Operations Plan), see hinode.msfc.nasa.gov/hops.html#requirements for details.

Please keep in mind that while IRIS is in eclipse season from early November through mid February, during this time frame IRIS will nevertheless be able to provide high quality observations for about 60 minutes out of every orbit (97 minutes). To maximize overlap with IRIS, requesting at least 1.5 hours of ALMA observations is the best option.
IRIS has no limitations for ALMA support from mid February onwards.

As the observation date nears, close communication on the timings and pointings of the ALMA observations will be required in order to allow Hinode and IRIS to coordinate successfully.

If you have questions about support for ALMA observations, please contact Sabrina Savage for Hinode ([email protected]) and Bart De Pontieu for IRIS ([email protected]).

Valery Nakariakov
30 Mar 2016

New Book: “Low-Frequency Waves in Space Plasmas” (published by Wiley)

From: Andreas Keiling keiling at ssl.berkeley.edu>, Dong-Hun Lee dhlee at khu.ac.kr>, Valery Nakariakov V.Nakariakov at warwick.ac.uk>

In this book, the editors have compiled a collection of review chapters, written by leading experts, on the topic of low-frequency waves in space plasmas. Its main objective is to give a concise and authoritative up-to-date look on where wave research stands: What do we know? What have we learned in the last decade? What are unanswered questions?

Organized into ten parts, each representing a specific space region, the book begins with waves in Earth’s ionosphere and progresses outward to various regions of Earth’s magnetosphere. Then, beyond geospace, waves in the solar wind, at the Moon, and in other planets’ magnetospheres are reviewed. Finally, the book finishes with waves in the Sun’s atmosphere.

More information, including a table of contents, can be found at the official Wiley website: www.wiley.com/WileyCDA/WileyTitle/productCd-1119054958.html

The book can be purchased in electronic form (E-Book) or as hardcover at the above website. Individual chapters can be downloaded from: onlinelibrary.wiley.com/book/10.1002/9781119055006

BBSO and NSO Announcement of Support for ALMA Observations

Joseph McMullin
31 Mar 2016

The Cycle 4 Call for Proposals for the Atacama Large Millimeter-submillimeter Array includes the long-awaited announcement that ALMA is now open for solar observing, opening an exciting new window to address key questions in solar physics.

Given the importance of this new science potential and the value of using all available diagnostics in these studies, the NSO and BBSO hereby declare our intention of making our respective facilities available for the acquisition of coordinated observations in support of all successful ALMA Cycle 4 solar proposals. Teams planning to submit ALMA Cycle 4 solar proposals may refer to this published declaration as evidence that such observations will be available, notwithstanding unavoidable limitations due to technical or weather problems.

NSO operates the Dunn Solar Telescope (DST) and BBSO the New Solar Telescope (NST), both of which employ advanced instrumentation for imaging, spectroscopy, and polarimetry. The spatial resolution (0.07-0.3 arcsec), temporal cadence (1-30 sec), and range of photospheric and chromospheric diagnostics are highly complementary to the ALMA capabilities. The small separation in longitude between Atacama and the western US favors the possibility of getting high-quality, simultaneous observations from these facilities. NSO also operates the SOLIS synoptic instrument that takes full-disk images of the photospheric and chromospheric magnetic field and intensity, while BBSO operates a full-disk H-alpha imager, part of the Global H-alpha Network.

We encourage teams preparing Cycle 4 submissions to contact either facility if details of the observational capabilities are needed. Teams should also inform the facilities as soon as possible this fall when the outcome of the selection process is known so that the suitable observing period can be scheduled.

The Problem of the Magnetic Field Gradients in Sunspots: Workshop at the Paris Observatory

Veronique Bommier
31 Mar 2016

3–5 October 2016 (from noon to noon)
Centre International d’Ateliers Scientifiques, Meudon Castle, Meudon Observatory, Meudon, France
cias.obspm.fr/fr/activities/details.php?id=145

organized by Veronique Bommier
SOC: V. Bommier, H. Balthasar, E. Landi Degl’Innocenti, J.M. Malherbe

In sunspots, the measured gradients respectively vertical (dBz/dz) and horizontal (dBx/dx+dBy/dy) largely differ in the observations, whatever the methods, instruments or spectral lines are. All the measurements agree on a vertical gradient of about 3 G/km on the one hand, and an horizontal gradient of about 0.3 G/km on the other hand, which surprisingly questions the vanity of the apparent div • B computed from these values. Thus S. Solanki wrote in a review devoted to sunspots in 2003, p. 184 (S. Solanki, Astronomy and Astrophysics Review, 2003, 11, 153): “No satisfactory solution has been found as yet for the unexpectedly small vertical gradients obtained by applying the div • B = 0 condition”.

The workshop is devoted to investigate the following question: do these measurements enable us to conclude about the local divergence of the magnetic field, and, if not, what effect explains the departure from zero of the observed value corresponding to a larger scale?

The workshop will be organized as follows: after presentation (V. Bommier), reports on the problem itself as observation result (H. Balthasar) and Stokes inversion and radiative transfer (E. Landi Degl’Innocenti), the discussion will remain free and open around a table, for together investigation of possible solutions or artifacts. Any other contribution prepared in advance is welcome.

Depending on the conclusions, the workshop would eventually be followed by a second one more aimed towards theory, in the following year.

Open Access paper by V. Bommier about this question: www.hindawi.com/journals/physri/2013/195403/

If you wish to participate, send an e-mail to V.Bommier_at_obspm.fr with the following information:

Rationale: The variable activity of stars such as the Sun is mediated via stellar magnetic fields, radiative and energetic particle fluxes, stellar winds and magnetic storms. This activity influences planetary atmospheres, climate and habitability. Studies of this intimate relationship between the parent star, its astrosphere (i.e., the equivalent of the heliosphere) and the planets that it hosts have reached a certain level of maturity within our own Solar System – fuelled both by advances in theoretical modelling and a host of satellites that observe the Sun–Earth system. In conjunction, the first attempts are being made to characterize the interactions between stars and planets and their coupled evolution, which have relevance for habitability and the search for habitable planets. This Symposium will bring together scientists from diverse, interdisciplinary scientific areas such as solar, stellar and planetary physics, atmospheric and climate physics and astrobiology to review the current state of our understanding of solar and stellar environments.  The Symposium is expected to fertilize exchange of ideas and identify outstanding issues – tackling which necessitates coordinated scientific efforts across disciplines.

Invited Speakers: Anil Bhardwaj (India), Cesar Bertucci (Argentina), Paul Charbonneau (Canada), Manuel Guedel (Austria), Gaitee Hussain (Germany), Moira Jardine (UK), Colin Johnstone (Austria), Laurène Jouve (France),  Eiichiro Kokubo (Japan), Hiroyuki Maehara (Japan), Jose Dias do Nascimento Jr. (Brazil), Rachel Olsten (USA), Katja Poppenhaeger (UK), Steve Saar (USA), Alexander Shapiro (Germany)

Specifics: The symposium will be held in the sea side town of Maresias, Brazil from 17–21 October, 2016. Further details, including registration, abstract submission, financial support and accommodation information are available at the conference websites:

SPD 2016: SDO/HMI Data Calibration Splinter Session

Todd Hoeksema
31 Mar 2016

The Heliospheric and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) provides full-disk vector and line-of-sight magnetograms, photospheric images, and Doppler maps for scientific research and space weather forecasting. Though the HMI team strives to provide the best calibrated data to the community, several varieties of systematic error still require better understanding and further development of mitigation approaches. We encourage scientists interested in working with HMI data to consider submission of poster presentations on HMI calibration to the 2016 SPD meeting. There will be a splinter session at the meeting to promote discussion of issues related to HMI calibration and plans for future work. Information about the instrument and calibration can be found at jsoc.stanford.edu/jsocwiki/HMICalibrationInfo

Editor’s Note

2015 SolarNews Instructions

Aimee Norton
01 May 2015

SolarNews is normally distributed on the first and fifteenth of each month. Please send in your submissions by midnight (UT-7) the day before.

The SPD Web site can be found at spd.aas.org. The HTML version of SolarNews can be found at spd.aas.org/SolarNews/archive/news.html or solarnews.nso.edu. Archived back issues can be retrieved at solarnews.nso.edu.

SolarNews submissions can be in plain text or HTML markup. Submissions should be made via the submission webform at solarnews.aas.org/

The online version contains in-line hyperlinks to all of the Web sites and e-mail addresses mentioned in the issue. A link to send email feedback to the contributor, without the email address being accessible, is included in each article.

To make an email address invisible within the body of a SolarNews posting, and inaccessible to robots that collect them for spam, simply format it as @@text to appear@@email-address@@, for example “contact @@Jane Doe@@[email protected]@@” will appear as “contact Jane Doe“.

To make a URL a “clickable” link in your posting, make sure that there is http:// (or https:// as appropriate) before it. Thus “solarnews.nso.edu” appears as simple text while
http://solarnews.nso.edu” will appear as “solarnews.nso.edu” and will allow the reader to access the URL by clicking on the link in the HTML version of SolarNews.   Of course, you can always just format the URL in an HTML submission; for example http://solarnews.nso.edu“>solarnews.nso.edu/, which can be useful for an ftp or other server than http[s].

You can check your submission at http://solarnews.nso.edu/Preview, which is updated hourly, and let us know if something needs to be changed, for example remove a duplicate submission.

Please try to keep meeting and workshop announcements to no more than one page (fewer than 60 lines of typed text with 72 characters per line), with a Web address for further information.
