Announcing RHESSI Science Nugget No. 187
by Hugh Hudson 29 Oct '12

29 Oct '12

No. 187, "Glasgow Callisto optimistic: first light comes in focus," by Heather Ratcliffe and Eduard Kontar. Glasgow's own solar radio observatory comes on line and detects a RHESSI flare. http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Glasgow_Callisto_optimi… 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.

FROM THE EDITOR ===================================================================== 1. NEW MAX MILLENNIUM CHIEF OBSERVER ------------------------------------ > From Dick Canfield <canfield at physics.montana.edu> Paul Higgins is the most recent addition to the MM_COs. He is presently finishing his PhD with the Astrophysics Research Group at Trinity College Dublin. For his undergrad, Paul attended Contra Costa College and transfered to UC Berkeley where he double majored in Physics and Astrophysics. He was a research assistant in the Particle Data Group at Lawrence Berkeley Laboratory and then in the Space Physics Research Group at Space Science Laboratory. His PhD research includes investigations into the relationship between dynamic sunspot group properties and the occurrence of flares, primarily relying on SOHO/MDI magnetic field observations. In the next two years he will do a postdoc between TCD and LMSAL on a topic related to his PhD. We are delighted to have him on board as a MM_CO. 2.
