We invite abstract submission for the National Astronomy Meeting 2017 session “The Physical Processes Underlying Space Weather: Formation, Eruption and Propagation of Coronal Mass Ejections”.
The aim of the session is to bring together solar and heliospheric physicists, both modelers and observers, to discuss the formation and evolution of magnetic flux ropes with particular focus on (1) what are the universal physical mechanisms responsible for triggering solar eruptions, (2) how and when magnetic flux ropes are formed, (3) how their structure evolves during their propagation through the inner heliosphere, and (4) how the structure of the interplanetary magnetic clouds relate to their source regions on the Sun.… continue to the full article

SECOND ANNOUNCEMENT: MREP2017
This conference will take place at the University of Cambridge (CMS) on 11-12 September, 2017 to mark Michael Proctor’s retirement.
The meeting will cover topics on which Mike’s scientific research has been focused throughout his career. We therefore encourage abstract submissions on dynamo theory, MHD, convection, magneto convection,pattern formation and other relevant topics.… continue to the full article
No. 296, “Suppression of Hydrogen Emission in an X-class White-light Solar Flare,” by Ondřej Procházka and Ryan Milligan. The absence of hydrogen signatures suggests an event buried in the deep solar atmosphere.
No. 295, “Radio Emissions from Double RHESSI TGFs”, by Andrey Mezentsev and Thomas Gjesteland: Lightning helps with microsecond timing calibrations, and is really interesting as a phenomenon of high-energy astrophysics.… continue to the full article
The Russian-British seminar of young scientists, chaired by Professor V.M. Nakariakov (Warwick, UK) and Professor A.T. Altyntsev (ISTP, Russia) will hold on the 18-21st of September in Irkutsk, Russia. The main topics include
• Analogies and differences between the coronal, solar wind and magnetospheric plasmas; and the ionospheric and chromospheric plasmas.… continue to the full article
