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?
