MAX MILLENNIUM NEWS 4 July 2012 CONTENTS 1. TRACING THE CONNECTIONS IN SOLAR ERUPTIVE EVENTS 2. E-PRINTS POSTED IN THE PAST WEEK 3. FROM THE EDITOR ===================================================================== 1. TRACING THE CONNECTIONS IN SOLAR ERUPTIVE EVENTS --------------------------------------------------- > From Gordon Emslie <emslieg (at) wku.edu> On behalf of the Science and Local Organizing Committees, I am pleased to invite the solar physics/heliophysics community to a conference/workshop entitled "Tracing the Connections in Solar Eruptive Events" to be held at the Sheraton Sonoma County Hotel, Petaluma, CA, from November 27 - December 2, 2012. The conference will be devoted to sharing analysis, interpretations, and results based on recent observations from various solar spacecraft, such as ACE, Fermi, Hinode, RHESSI, SDO, SOHO, and STEREO. This is the third in a series of "California Wine Country" conferences, and the format will be a mixture of plenary sessions and cross-connected working groups, following the highly successful model established by earlier conferences in the series (Sonoma 2004 and Napa 2008). The meeting website can be found at http://hessi.ssl.berkeley.edu/petaluma/index.shtml . The overarching objective of the conference is to examine the connections amongst the phenomena that lead to solar eruptive events. The current slate of themes includes: - Measuring the Coronal Magnetic Field; - Connections to, and Reactions of, the Large-Scale Corona; - Large-scale Magnetic Connectivity of Active Regions; - Transfer of Energy to, and Storage of Energy in, the Corona; and - The High-Energy Particle - Flare - CME connection. We have assembled a cast of outstanding invited speakers for these sessions. Working groups will address topics such as: - Energy Transfer throughout a Solar Eruptive Event; - Global Energetics of an Ensemble of Events; - Coronal Influences to the Lower Atmosphere; - CME Initiation and Type II Bursts; - The Release of Energetic Particles in the Low Corona; - Flows vs. Waves; and - Microflares/Nanoflares; The "manifestos" for the working groups can be found at http://hessi.ssl.berkeley.edu/petaluma/workinggroups.shtml Additional working group topics may be created, depending on the content of the abstracts that are submitted. We also intend to have a "presidential-candidate" style debate on the topic of "How much closer are we to flare prediction?â" The registration site: http://hessi.ssl.berkeley.edu/petaluma/registration.shtml and abstract submission site http://hessi.ssl.berkeley.edu/petaluma/abstracts.shtml are now open. I invite you to register, submit your abstract, and make your hotel reservations. Rooms booked through the link supplied on the conference page will receive the conference rate. https://www.starwoodmeeting.com/StarGroupsWeb/res?id=1112156251&key=6482F A limited amount of funds has been identified for the purpose of providing travel support for students and new postdocs. The closing date for such applications is July 20, 2012. We invite interested individuals to visit the site at http://hessi.ssl.berkeley.edu/petaluma/travel_support.shtml for more details. I look forward to seeing you in Northern California wine country later in the year! Gordon Emslie Chair, SOC 2.

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.
