New EIS nugget
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. Dr Lucie Green Mullard Space Science Laboratory Holmbury St. Mary Dorking Surrey RH5 6NT +44 (0)1483 204103 www.mssl.ucl.ac.uk/~lmg

No. 179, Dimmings and Sustained Gamma-Ray Events, by Hugh Hudson and Nicola Omodei. Coronal disruptions reveal themselves as depletions and long-duration gamma-ray emission. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Dimmings_and_Sustained_… 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.

MAX MILLENNIUM NEWS 20 June 2012 CONTENTS 1. NEW "GREAT FLARE WATCH" ANNOUNCEMENTS 2. E-PRINTS POSTED IN THE PAST WEEK 3. FROM THE EDITOR ===================================================================== 1. NEW "GREAT FLARE WATCH" ANNOUNCEMENTS ---------------------------------------- The solar flare science derived from observation of >50 MeV gamma rays by the Fermi Large Area Telescope (LAT) can be enhanced significantly if the overall solar exposure and duty cycle is increased. This can be done by a change in the spacecraft pointing modes during times of high solar activity. Through a "Great Flare Watch" announcement in the Max Millennium Message of the Day (MOTD), the Max Millennium Chief Observers aim to provide an appropriate alert. Goals and target selection criteria are described in Max Millennium Coordinated Observing Plan 018, "REGION LIKELY TO PRODUCE GREAT FLARES", http://solar.physics.montana.edu/max_millennium/ops/op018/op018.html A unique Solar Target of Opportunity operational plan, which will be used in response to Great Flare Watch alerts, has been organized by the Fermi team. Of course, an active region that produces great flares will be of interest to other ground and space-based instruments, as well. If your instrument can beneficially use this alert of high probability of flares of GOES class >X5, please contact canfield(a)physics.montana.edu about such practical matters as the UT timing of the MOTD. 2.
