RHESSI Science Nuggets in July 2016
by Hugh Hudson 29 Jul '16

29 Jul '16

No. 279, “Unexpected distributions of solar electrons in the heliosphere,” by Andreas Klassen and the SEPT/STEREO team: Solar energetic electrons may have complicated and informative distributions in the interplanetary medium No. 278, “Initiation of a type II radio burst without a CME,” by Pankaj Kumar. Davina Innes, and Kyung-Suk Cho: A global coronal shock wave without a CME driver. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets listing the current series, 2008-present, and http://sprg.ssl.berkeley.edu/~tohban/nuggets/ for the original series, 2005-2008. We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.

2016 AGU Fall Meeting Session SH011 -- New Observations and Recent Results for Solar X-ray Spectral Measurements and their Applications for Earth's Atmosphere -- Call for Abstracts
by Amir Caspi 29 Jul '16

29 Jul '16

Dear Colleagues, We cordially invite you to submit a contributed abstract for the Fall AGU 2016 meeting, session SH011, “New Observations and Recent Results for Solar X-ray Spectral Measurements and their Applications for Earth’s Atmosphere.” This session is inspired by recent and upcoming missions to measure the critically under-observed ~0.2-5 keV (~0.25-6 nm) spectral range, including the Miniature X-ray Solar Spectrometer (MinXSS) CubeSat; the session includes hard X-rays, and is not limited to just the soft X-ray range. We invite presentations discussing spectrally-resolved solar X-ray measurements (including spectroscopy and imaging, both soft and hard X-rays), new techniques, and instrumentation; their implications for studies of plasma heating and particle acceleration in the flaring and quiescent corona; and their influence on Earth’s upper atmosphere. The full session description, and a link to submit an abstract, can be found here: https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session13377 The deadline to submit an abstract is 3 August 2016. We look forward to your submissions! Conveners: Amir Caspi (SwRI), Tom Woods (CU/LASP) --- Amir

New Solar Flare Finder tool available in SSWIDL
by Ryan Milligan 14 Jul '16

14 Jul '16

Our current fleet of space-based solar observatories offer us a wealth of opportunities to study solar flares over a range of wavelengths, and the greatest advances in our understanding of flare physics often come from coordinated observations between different instruments. However, finding or keeping track of which flares have been observed by specific combinations of instruments can be cumbersome and time consuming. To alleviate this issue, and provide access to a broader range of flaring events observed by GOES, RHESSI, Hinode (EIS, SOT, and XRT), SDO/EVE (MEGS-A and MEGS-B), and IRIS, a new interface has been developed and incorporated into SSWIDL. After updating your SSWIDL directory, simply type IDL> solar_flare_finder to bring up the widget. After selecting a time range (it defaults to the beginning of the SDO mission to the present day), and which combination of instruments you require to address a given science question, along with options for GOES class, maximum energy observed by RHESSI, and flare location (disk or limb), etc, click the Search button. This will return a list of flares that conform to your search criteria. Clicking on a given flare in this list will call up a plot that containing 1) the GOES X-ray lightcurves with the timing of your chosen observations overlaid, 2) the RHESSI lightcurves up to the maximum recorded energy, and 3) a RHESSI full-disk quicklook image with the fields of view of the different instruments overlaid. The option exists to also download a copy of this .png file to your current working directory, or an IDL .sav file containing the metadata used in generating the plots. These plots are also accessible via the RHESSI browser (http://sprg.ssl.berkeley.edu/~tohban/browser/) for flares observed by RHESSI since the launch of SDO. Check the box marked “Cross-Mission Synoptic”, and expand it to include the “Hinode/EVE/IRIS” check box. Future improvements to this service will include adding flares that were not observed by RHESSI, adding additional instruments (e.g. Fermi, NoRH, GOES/EUVS, etc), and direct access to the data itself. Please address any questions, comments or requests to r.milligan(a)qub.ac.uk<mailto:r.milligan@qub.ac.uk>. Thanks to Kim Tolbert for her help with designing the widget, Albert Shih for incorporating the plots into the RHESSI browser, and Dominic Zarro for help with the Hinode/EIS software.
