RHESSI Nuggets in March 2019
by Hugh Hudson 24 Mar '19

24 Mar '19

No. 347, “Persistent quasi-periodic pulsations detected during the large X8.2 solar flare,” by Laura Hayes and Peter Gallagher: The most beautiful flare has the most beautiful pulsations! No. 346, “Is the coronal magnetic field braiding?” by Markus Aschwanden. An iconic cartoon does not relate well to the observations. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting.

CESRA Workshop 2019: - registration and abstract submission are open
by Eduard Kontar 13 Mar '19

13 Mar '19

Dear Colleagues, We are pleased to announce registration/abstract submission for the next CESRA Workshop, “CESRA2019: The Sun and the inner heliosphere” which will be held on July 8th – 12th, 2019, at Telegrafenberg, Potsdam, Germany. http://meetings.aip.de/cesra2019/cms/ CESRA, the Community of European Solar Radio Astronomers, organizes triennial workshops on investigations of the solar atmosphere using radio and other observations. Although special emphasis is given to radio diagnostics, the workshop topics are of interest to a large community of solar physicists. The format of the workshop will combine plenary sessions and working group sessions, with invited review talks, oral contributions, and posters. To register and to submit the abstract please follow the link: http://meetings.aip.de/cesra2019/registration/ The CESRA 2019 workshop will place an emphasis on linking the Sun with the heliosphere, motivated by the launch of Parker Solar Probe in 2018 and the upcoming launch of Solar Orbiter in 2020. It will provide the community with a forum for discussing the first relevant science results and future science opportunities, as well as on opportunity for evaluating how to maximize science return by combining space-borne observations with the wealth of data provided by new and future ground-based radio instruments, such as ALMA, E-OVSA, EVLA, LOFAR, MUSER, MWA, and SKA, and by the large number of well-established radio observatories. On behalf of the CESRA Board and the local SOC representatives, Eduard Kontar, Gottfried Mann, Alexander Warmuth

RHESSI Nuggets in February 2019
by Hugh Hudson 20 Feb '19

20 Feb '19

No. 345, “A Energetic Pre-flare: Electron Distributions in Magnetic Reconnection Outflows,” by Marina BATTAGLIA, Eduard KONTAR, and Galina MOTORINA. Assessing energy partition in a very interesting pre-impulsive flare development. No. 344, “Linear Polarization in H-alpha Flares,” by Tomoko KAWATE and Yoichiro HANAOKA. H-alpha polarization (perhaps implying electron beams) is rarely observable, but in one case there are suggstive results. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting.

MAX MILLENNIUM NEWS 13 February 2019 CONTENTS 0. A MILESTONE, AND THANKS, FOR THE E-PRINT ARCHIVE 1. E-PRINTS POSTED IN THE PAST WEEK 2. FROM THE EDITOR ===================================================================== 0. A MILESTONE, AND THANKS, FOR THE E-PRINT ARCHIVE =================================================== <richard.canfield at montana.edu> This week the Max Millennum Solar Physics E-Print Archive logged it's 4000th submission! That's trivial on the scale of the Cornell/LANL arXiv, of course, but it demonstrates empirically what we all know -- there is value to us in an archive that is specific to a subdiscipline -- solar and heliospheric actvity, in this case. It gives me great pleasure to thank Alisdair Davey for his seminal role in creating the E-Print Archive in mid-2000 and maintaining it ever since. I searched the Max Millennium Science Mail Archive to get a sense of the duration of his committment. I found that the Max Millennium News message announcing the availability of the enhanced E-Print archive came shortly after a message from Bob Lin, reporting that RHESSI had been reconfirmed for flight after the spacecraft was severely damaged as the result of the shake table malfunction during a vibration test! 1.
