Last Call for Abstracts for AOGS Session ST27 New Insights Into The Physics Of White-light Flares
by Juan Carlos Martínez Oliveros 29 Feb '16

29 Feb '16

Dear All, We invite contributions to the session (ID#: ST27) “New Insights Into The Physics Of White-light Flares” at the AOGS meeting in Beijing, 31 Jul to 5 Aug, 2016. Details on the session follow. We would like to remind you that the abstract submission deadline was extended to 4 March 2016. Abstracts can be submitted using the following link: http://www.asiaoceania.org/aogs2016/public.asp?page=abstract.htm Best regards, Juan Carlos Martinez Oliveros Hugh S Hudson Lucia Kleint Mingde Ding --------------------------------------------- Session Title: New Insights Into The Physics Of White-light Flares Session Description: The white-light continuum of a solar flare was the first manifestation of a flare ever detected, and this continuum emission contains a large fraction of the total luminous energy of a flare. Thus its identification has always posed an important problem for solar and stellar physics. A zoo of phenomena accompanies these events and their analysis can provide a wealth of information about the solar atmosphere. The focus of the discussion is the manifestation in the visible continuum of flares, from the corona to the solar interior and how multi wavelength observations (RHESSI, IRIS, SDO, Hinode, infrared, NoRH, OVSA) can help our understanding of the mechanics of momentum and energy transfer in the solar atmosphere.

Last Call for abstracts to the session ST26 Multiwavelength and In-situ Observations Of CME and Flare Evolution and Dynamics at AOGS 2016
by Juan Carlos Martínez Oliveros 29 Feb '16

29 Feb '16

Dear All, We invite contributions to the session (ID#: ST26) “Multiwavelength and In-situ Observations of CME and Flare Evolution and Dynamics” at the AOGS meeting in Beijing from July 31 to August 5, 2016. Details on the session follow. We would like to remind you that the abstract submission deadline was extended to 4 March 2016. Abstracts can be submitted using the following link: http://www.asiaoceania.org/aogs2016/public.asp?page=abstract.htm Best regards, Juan Carlos Martinez Oliveros Ying Liu Hazel Bain David Sundkvist --------------------------------------------- Session Title: Multiwavelength and In-situ Observations Of CME and Flare Evolution and Dynamics Session Description: Flares and CMEs are two spectacular manifestations of the explosive release of magnetic energy in the solar atmosphere. The released magnetic energy is transformed into kinetic and thermal energy and radiations. The focus of this session is to discuss how multi-wavelength observations and in situ measurements from current (IRIS, SDO, RHESSI, Hinode, NoRH, NRH, OVSA, STEREO, Wind, ACE) and future (Solar Orbiter, Solar Probe Plus) instruments and theoretical modeling can help our understanding of the mechanics, dynamics and evolution of these phenomena in the corona and interplanetary space.

RHESSI's upcoming fifth anneal
by Shih, Albert Y. (GSFC-6710) 22 Feb '16

22 Feb '16

To RHESSI collaborators: RHESSI has been successfully operating in space for over 14 years now, and it is once again time to rejuvenate the detectors through an "anneal" procedure. RHESSI's germanium detectors will be heated up from their operating temperature of ~130 K to ~70 deg C (~343 K), held at that temperature for ten days, and then cooled back down. The detectors degrade steadily over time due to radiation damage from charged particles, and heating up the germanium restores lost sensitivity and resolution. These detectors have been previously annealed four times, most recently in 2014. We plan to start the anneal on February 23 (UT), and the entire procedure is estimated to take about two months. During this time period, RHESSI will be unable to make X-ray or gamma-ray observations. If you have any questions about this anneal, please feel free to contact me.

by Hugh Hudson 17 Feb '16

17 Feb '16

“When the Earth’s atmosphere becomes dynamic…”, by Temmer, Krauss, and Veronig: The Earth’s atmosphere reacts strongly to the occurrence of flares and CMEs. 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.

This workshop, "The Sun's Chromosphere in the Era of ALMA, IRIS, and DKIST," will take place March 15-18 in Boulder, CO (USA). See http://www.nso.edu/workshops/SunAID and its links for full details. The workshop aims at exploiting new data and simulations from existing facilities in anticipation of the revolutionary capabilities of ALMA and DKIST. The program is complete and includes practical demonstrations as well as planning aids for the first ALMA solicitation for solar proposals. Some additional registrations (and poster presentations) would be welcome.
