This one-week school aims at giving young scientists a primer on the impact of solar variability on the Earth's climate. This a timely but also controversial topic that is of major scientific importance. Progress on this issue has been slow, partly because of the lack of interactions between different communities. This is precisely why this school will address the Sun-climate connection in a highly multidisciplinary fashion, by offering the students a panel of lectures given by experts coming from different communities.

Maximal energy of solar acceleretors:Evidence from space and earth's surface measurements

Authours: A. Chilingaryan, K. Bostanjyan, H. Rostomyan 

On January 20, 2005, 7:02-7:04 UT the Aragats Multidirectional Muon Monitor (AMMM) located at 3200 m registered enhancement of the high energy secondary muon flux (threshold ~5 GeV). The enhancement, lasting 3 min has statistical significance of ~4? and was related to the X7.1 flare seen by the GOES, and very fast (>2500 km/s) CME seen by SOHO. Worldwide network of neutron monitors detects Ground Level Enhancements (GLE) #69 arriving very fast after flare; recovered energies of solar protons demonstrate rather hard spectra prolonged up to 10 GeV. The solar proton spectrum incident on the Earth's atmosphere was simulated and transport till AMMM detector located under 14 m of soil and concrete. The most probable minimal solar proton energy corresponding to the measured 5 GeV muon flux is within 20-25 GeV. On March 7, 2012 Large aperture telescope of Fermi gamma-ray observatory detected the ever highest energy gamma rays from the Sun with energy about 4 GeV. The minimal energy of the solar protons accelerated during the flare and producing 4 GeV gamma rays should be ~25 GeV. Thus, both measurements with secondary muons and gamma rays prove maximal energy of solar accelerators not smaller than 25 GeV.
