by Lucie Green 29 Nov '12

29 Nov '12

Dear all, We are pleased to announce the release of a new EIS nugget. This month we celebrate one year of the EIS flare catalogue and the dataset that EIS is collecting. Please visit the nugget here: http://msslxr.mssl.ucl.ac.uk:8080/SolarB/nuggets/nugget_2012feb.jsp We welcome nugget contributions from the community. Please contact Lucie Green if you are interested.

Fermi Solar Data Analysis Workshop - August 22-23
by Andrew Robert Inglis 30 May '12

30 May '12

Dear colleagues: We are pleased to announce the Fermi Solar Data Analysis Workshop to be held at Goddard Space Flight Center on August 22-23, 2012. Although primarily an Astrophysics observatory, the Fermi Gamma-ray Space Telescope, and its Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT), provide unique capabilities in the 8 keV - 300 GeV band to monitor and study both the quiescent and flaring Sun. Fermi has already made many observations of solar X-ray and gamma-ray emissions, and many more can be anticipated during the next few years with the peak in solar activity expected in 2013. This workshop is meant to be informal and interactive. It will start with reviews of X-ray and gamma-ray solar studies to date, including results already obtained with the Fermi observatory. Extensive tutorials will be given on both GBM and LAT data analysis techniques, with time set aside for hands-on practice on your own laptop. We invite all of those interested in learning more about Fermi’s Solar capabilities, and interested in interacting with experts in the field, to attend this 2-day workshop. Due to NASA badging requirements, we encourage participants to register as early as possible. Note that it can take up to 2 months to obtain badges for some visitors. Therefore, please register by June 20th. Late registration may be accepted if badging requirements can be met. The workshop itself will be free to all participants, and include coffee breaks. We regrettably are unable to assist with travel funds for any participants. Please see http://fermi.gsfc.nasa.gov/science/mtgs/workshops/da2012_solar/ for more information and updates as they become available.

Announcing a new RHESSI Science Nugget, No. 176
by Hugh S. Hudson 22 May '12

22 May '12

No. 176, Time Profiles of Solar Flare Densities, by Ryan Milligan and Michael Kennedy. The EUV spectra from EVE include nice density diagnostics. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Time_Profiles_of_Solar_… Older Nuggets are available at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets (the current series, 2008-present), and at http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (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.
