Monday afternoon and Tuesday morning CME session
• Continuation from last year’s session.• What did we learn from:
– new remote-sensing capabilities?– combined with in-situ measurements?– and with ever improving numerical simulations?
• Science questions:– CME kinematics,– CME rotation, deflection, expansion,– Successive CMEs.
• Space Weather questions:– CME arrival time and prediction of CME properties.
• What’s next for research on CMEs?
Agenda & discussion leaders
• This afternoon DL: Alexis Rouillard (GMU/NRL/NASA). We expect the discussion to focus on heliospheric properties of CMEs.
• Intro to the events by WGL Ying Liu.• Probable contributors to the discussion: B. Wood, J.
Byrne, M. Bisi, D. Odstrcil, P. Corona-Romero.
• Tomorrow morning DL: Alysha Reinard (NOAA/SWPC). We expect the discussion to focus on solar properties of CMEs and their relations with heliospheric properties.
• Probable contributors: T. Török, S. Titov, Z. Mikic, W. Manchester, R. Evans, J. Gilbert.
3 main events: 1- April 3, 2010 CME
– Observed remotely by ST-A and ST-B.– In-situ by ACE.– Geo-effective and fast CME (800-1000 km/s).– Already well studied and published:
• Rouillard et al. (2011), Liu et al. (2011), Wood et al. (2011), Möstl et al. (2010)
– We probably see a shock/wave in HI.
April 3, 2010 CME– Observed remotely by ST-A
and ST-B.– In-situ by ACE; geo-
effective.– SEPs at L1 and ST-B and
A?
