A multidisciplinary team involving researchers from IAS, IPNO, ISMO, and CSNSM in Orsay, and GSI in Darmstadt (Germany) has characterized in the laboratory the effects of heavy cosmic rays on the structural change and sputtering of small carbonaceous species released when cosmic rays, simulated and accelerated at the GSI accelerator, hit a carbonaceous interstellar dust grain analogue. The measurements performed during such simulations allow knowing the processes induced by radiations observed in space and their relative importance. The objective of these studies is to provide data on the evolution of the interstellar material, to understand its further evolution and provide constraints for modelers of astrophysical environments.

The Sun is currently in a quiet phase ; the next activity peak is is expected to happen in about five years, but in any event, a big solar-storm can strike anytime, not just at the peak of the solar cycle. Scientists and representatives of industrial sectors affected by space weather met at the Met Office to discuss how the solar-flare forecasting system FLARECAST should be designed to best serve user needs.
