GOES/EUVS Data Now Available Through SSWIDL.

Ryan Milligan
23 May 2016

The three most recent GOES satellites – GOES-13, -14, and -15 – each have onboard an EUV Sensor (EUVS) in addition to the more familiar X-ray Sensor (XRS). EUVS has five channels (A, B, C, D, and E) that span the 50-1270A range, with the E-channel centered on the Lyman-alpha line of hydrogen at 1216A in a broadband manner similar to SDO/EVE MEGS-P, although their flare profiles are inexplicably different (see Milligan & Chamberlin 2016). Studies of Lyman-alpha emission are important from both a space weather and solar flare physics perspective as Lyman-alpha is a strong driver of changes in ionospheric composition and dynamics, as well as being a substantial radiator of flare energy from the chromosphere during the impulsive phase.

To that end, the GOES/EUVS data have recently been incorporated into the GOES workbench, which is accessible via SSWIDL, for ease of use by the heliophysics community. While GOES-13 has been taking sporadic measurements in the EUV since mid-2006, GOES-14 data are available from mid-2009 to mid-2010, and again for a few months in late 2012. GOES-15 has been much more consistent, observing the Sun continuously since early 2010, although data are currently only available up until October 2014, with more recent data becoming available soon. To access the GOES workbench, simply type IDL> goes. This will bring up the parent widget from which you can select the EUVA, EUVB, or EUVE data from the ‘Archive’ drop down menu.

Note that the Lyman-alpha profiles exhibit a dip in emission for around four hours each day due to geocoronal absorption by the earth’s atmosphere. For more information on GOES EUVS data, refer to www.ngdc.noaa.gov/stp/satellite/goes/doc/GOES_NOP_EUV_readme.pdf, and for details on how these data are incorporated into SSWIDL, along with the command line routines, please visit hesperia.gsfc.nasa.gov/rhessidatacenter/complementary_data/goes.html All credit for this effort goes to Kim Tolbert at NASA/GSFC, with thanks also to Janet Machol at NOAA/NGDC for her advice and assistance.

Draft NASA LWS TR&T 2017 Science Topics Released for Comment

Mark Linton
31 May 2016

Dear Colleagues,

This spring, we solicited your input for Living with a Star Targeted Research and Technology (LWS TR&T) Focused Science Topics for the ROSES 2017 Announcement of Opportunity and the response was amazing. We received 57 topics from all areas of Heliophysics and many comments. We are thrilled with your response.

We met in mid-May to carefully review all of these community suggested science topics, keeping in mind the overall Living with a Star goals and the TR&T Strategic Science Areas (SSAs). Based on all of this, we have prepared a draft set of 13 topics, appended here for your inspection and comment. We considered all submitted topics very carefully and created Focused Science Topics that include as much of this input as possible.

Please keep in mind that these are draft topics. We are now soliciting community feedback on these draft topics, as the next, critical stage of this year’s process of generating science topics.

All of these draft topics have been posted on our website at lwstrt.gsfc.nasa.gov/2017DraftTopicsForComments with input boxes for comments and feedback on each individual topic, as well as on the overall process. The comment period will remain open until July 18 (the Monday following the SHINE meeting). The topics will be presented both as posters and as LWS TR&T town hall discussions during the SPD meeting (town hall at 12:30pm June 1), the CEDAR/GEM meeting (town hall at 9:45am June 23), and the SHINE meeting (town hall at 8pm July 12) to expose them to as much community input as possible.

After this comment period closes, the committee will meet again to review the community feedback on the topics and, based on this feedback and on the LWS and TR&T goals, to finalize the topics for presentation to the NAC Heliophysics Subcommittee, and via that subcommittee, to NASA Headquarters.

We look forward to your feedback on these draft topics.

Sincerely,

Mark Linton, co-chair
Eftyhia Zesta, co-chair
On behalf of the LWS TR&T Steering Committee

Probing Alfvenic waves in coronal holes with the Coronal Multichannel Polarimeter

Deadline Friday 17th June 2016

www.findaphd.com/search/ProjectDetails.aspx?PJID=75560&LID=2317

Alfvénic waves are thought to be one of the main mechanisms responsible for accelerating the solar wind to speeds of around a million miles per hour. The PhD project aims to investigate the properties of these waves in coronal holes through analysis of data from the Coronal Multichannel Polarimeter, a telescope based in Hawaii. It is expected that the student has either a degree in Mathematics and/or Physics. Experience with coding in a scientific language (e.g., C, C+, IDL, Python) will be looked upon favourably. The PhD project will be a three-year joint venture between Northumbria University, (Newcastle, UK) and the High Altitude Observatory at the National Centre for Atmospheric Research (Boulder, Colorado, USA). The candidate will be able to decide where they spend the majority of their time, but part of the project will have to be spent at the other institute. The funding for this project will be sought from the Newkirk Fellowship once a candidate has been identified. Please note this means that success in the first stage of selection does not guarantee successful funding of the project and PhD.

Eligibility and How to Apply:

Please note eligibility requirement:
  • Academic excellence of the proposed student i.e. 2:1 (or equivalent GPA from non-UK universities [preference for 1st class honours]; or a Masters (preference for Merit or above); or APEL evidence of substantial practitioner achievement.
  • Appropriate IELTS score, if required.

For further details of how to apply, entry requirements and the application form, see: www.northumbria.ac.uk/research/postgraduate-research-degrees/how-to-apply/

Meeting Announcements

SHINE 2016 Session “Observational Signatures and Modeling of Intermittent Reconnection in the Solar Corona” – Call for Abstracts

Silvina Guidoni
16 May 2016

Abstract submission deadline: June 9th, 2016.

We would like to invite you to our session about observational signatures and modeling of intermittent reconnection in the solar corona at this year’s Solar Heliospheric and Interplanetary Environment (SHINE) Workshop (shinecon.org/CurrentMeeting.php), to be held from July 11th to 15th, 2016, in Santa Fe, New Mexico.

Our two “scene-setting” speakers will provide reviews on current observations and modeling of reconnection in the solar corona. Discussion with the audience is expected and indeed hoped for throughout. Poster presentations from the session are on display for the whole week. Those who wish to make (or refute) a particular point related to the discussion may bring one (at most two) slides that can be quickly put up on the main projector. We encourage your participation and hope that you will share this announcement with colleagues.

The discussion will be based on the following questions:

—What solar corona observations show intermittency?
—How can we characterize 3D reconnection from these observations? What drives the intermittency in reconnection?
—What are the roles of ideal and resistive instabilities?
—Is all solar coronal reconnection intermittent? Why or why not?

Full session abstract: (shinecon.org/shine2016/session2016.php#session12)

Looking forward to seeing you in Santa Fe, NM!

Conveners: Silvina Guidoni, Peter Wyper, Carrie Black, and Nick Murphy

SHINE 2016 Session “Coronal magnetic field in the context of the spatial and temporal behavior of SEP events”

Nariaki Nitta
27 May 2016

shinecon.org/shine2016/session2016.php#session3

It is widely agreed that the coronal magnetic field is of critical importance in understanding many phenomena that originate from the Sun.  We have organized a session at this year’s SHINE Workshop to actively discuss the current state of coronal magnetic field observations and modeling.  We will focus on the following questions: how are current observations and modeling used to compute key parameters in heliospheric events, and how can we improve our understanding with existing and/or future data and tools.

The proposed session was motivated by solar energetic particle (SEP) events that were observed at widely separate longitudes in the heliosphere rather quickly after the eruption (e.g. the “circumsolar” SEP event on 3 November 2011).  Making further progress on our understanding of these wide-longitude events will rely on a more sophisticated use of magnetic field data and modeling.  The five most recent SHINE Workshops hosted sessions that discussed closely related topics. This year our focus is on the coronal magnetic field as it relates to both SEP and non-SEP topics.

If you have an interest in any aspects of the coronal magnetic field such as measurement, modeling, application, etc, please attend our session. The invited scene-setting speakers will introduce the current state of coronal magnetic field studies and trigger further discussions on inter-related subjects.  As in other SHINE sessions, the primary contributions will be in the form of a poster: note the 9 June deadline for the abstract. If you are interested in presenting related work during the session itself (one or two slides), please inform the conveners of the subject matter.

Conveners: Nariaki Nitta, Ming Zhang, Eric Christian and Georgia de Nolfo
