Presentation Transcript

  1. 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?

  2. 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 CMEsand their relations with heliospheric properties. • Probable contributors: T. Török, S. Titov, Z. Mikic, W. Manchester, R. Evans, J. Gilbert.

  3. 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.

  4. April 3, 2010 CME ACE • Observed remotely by ST-A and ST-B. • In-situ by ACE; geo-effective. • SEPs at L1 and ST-B and A? STEREO B Courtesy Y. Liu

  5. 2- August 2010 events • 4 CMEs on August 1, 2011 + 1 on July 30 (pre-conditioning). • 2 workshop in Europe this year on the events. A number of publications in prep. or submitted. • Evidence of CME-CME interaction. • Type II burst.

  6. 3- Feb. 15, 2011 CME • X2.2 flare. Type II burst - SDO observations

  7. Advertisements • Topical Issue of Solar Physics: • Observations and Modeling of the Inner Heliosphere. • Guest Editors: M. Bisi, R. Harrison, N. Lugaz. • Deadline for abstract: July 29, 2011. • Deadline for submission: November 25, 2011. • AGU Session (1 out of 24!!) SH 15 • Heliospheric Transients and Implication for L4 mission. • Conveners: Möstl, Liu & Lugaz. • Invited Speakers: Webb, Gopalswamy & Optiz. • Deadline: August 4, 2011.
