Hurricanes Irma and Maria Cause Further Delay of Heliophysics Supporting Research Full-Proposal Due Date

From: Arik Posner (arik.posner at nasa.gov)

On September 21st, the ROSES-17 Heliophysics Supporting Research program due date for full proposals has been delayed further. The new  due date of Oct. 12, 2017 (moved from Sept. 28, 2017) gives more time to all proposers, and is aimed in particular at those who are adversely affected by hurricane damage.

Space Weather Journal Special Collection on Early September  2017 Solar and Geomagnetic Activity

From: Delores Knipp (dknipp at agu.org)

The editors of Space Weather are organizing a special collection to highlight the strong-to-severe space weather of 4-10 September 2017.  This interval was one of the most flare-productive periods of now-waning solar cycle 24.  Solar active regions (AR) 2673 and 2674 both matured to complex magnetic configurations as they transited the disk.  AR2673 transformed from a simple sunspot on 2 September to a complex region with order-of-magnitude growth on 4 September, rapidly reaching beta-gamma-delta configuration.  In subsequent days the region issued three X-class flares and multiple partial halo ejecta.  Combined, the two active regions produced more than a dozen M-class flares.   As a parting shot AR2673 produced: 1) an X-9 level flare; 2) an associated moderate solar energetic particle event; and 3) a ground level event, as it arrived at the solar west limb on 10 September.   From 4 -16 September the radiation environment at geosynchronous orbit was at minor storm level and 100 MeV protons were episodically present in geostationary orbit during that time frame.  The early arrival of the coronal mass ejection associated with the 6 September X-9 flare produced severe geomagnetic storming on 7 and 8 September.  The full set of events was bracketed by high speed streams that produced their own minor-to-moderate geomagnetic storming.

This interval is covered by, perhaps, the best set of heliospheric and space weather instruments ever to witness a significant event. We call for papers that address the heliospheric and geospace disturbances, and highlight how ground- and space-based instrumentation, combined with improved models allow us to understand the origin, dynamics and consequences of these storms.  We are particularly interested in “effects and impacts” papers, as there have been a number of media reports that HF radio blackouts caused by the X-flares disrupted emergency communications vital to recovery efforts following Hurricane Irma. We also welcome papers that assess the importance of these impacts and any other practical impacts arising from the space weather events in early September 2017.  Additionally, we encourage papers that address the direction, propagation and arrival time of the heliospheric structures (shock, sheath and/or core) that led to periods of forecast and/or observed strong southward Bz.

Monday Science Telecon

From: David Sibeck (david.g.sibeck at nasa.gov)

At 12:00 noon EST on Monday (October 2), we plan to hold the next in our ongoing series of science telecons. The speaker this Monday will be Kyungguk Min from the Johns Hopkins University Applied Physics Laboratory. The topic will be "Ion Bernstein instability as a possible source for O+ harmonic waves observed by Van Allen Probes".

The telecom will be broadcast live via webex. If you would like to join, please
go to http://uclaigpp.webex.com/, search for the ‘Dayside Science' meeting, enter your name and contact information, and then the meeting password, which is Substorm1!

To hear the audio, do not dial the number that pops up on the webex website. Instead, please dial the following toll free (in the United States) number:

PhD Student Position / Magnetospheres in the Outer Solar System

From: Sven Simon (sven.simon at eas.gatech.edu)

The “Magnetospheres in the Outer Solar System” (MOSS) group at the Georgia Institute of Technology (Atlanta, USA) invites applications for a PhD student position in theoretical/computational space plasma physics. The PhD student will carry out numerical simulations of the interaction between small solar system bodies and their plasma environments. In particular, we aim to better understand the interaction of Jupiter’s Galilean moons (Io, Europa, Ganymede, Callisto) and Saturn’s largest moons (Titan, Enceladus, Rhea, Tethys, Dione) with the magnetospheres of their parent planets. The simulations will support the interpretation of data from past (Galileo, Cassini) and future (JUICE, Europa Clipper) spacecraft missions. Information on the current research activities of the group can be found at http://svensimon.gatech.edu.

The successful candidate is expected to hold a university degree in (theoretical) physics, astrophysics, space physics or geophysics. Programming experience is required for the position. Undergraduate students who will complete their degree within the next year are strongly encouraged to apply. Starting date is either 01 January 2018 or 15 August 2018, depending on the availability of the successful candidate. Interested candidates should send a CV, a short statement of research interests (half a page) and the names of two potential references to sven.simon at eas.gatech.edu. Georgia Tech is an Equal Education/Employment Opportunity Institution.
