Title: Capabilities of coordinated white-light and radio wave observations


1
Capabilities of coordinated white-light and radio
wave observations
  • Stereo meeting, Hamburg, 1-4 May 2005
  • M. Pick,

2
A new web site for radio monitoring M. Pick, M.
Maksimovic, J. L. Bougeret, A. Lecacheux, R.
Romagnan and A. BouteilleLESIA, Observatoire de
Paris
  • Why a web site for radio monitoring ?
  • Main objectives
  • -Radio associated with CMEs, onset,development
  • -Electron beams from the low corona to the
    interplanetary medium
  • Web site under construction
  • -will not include microwave data
  • -will include dm-km data
  • - SECCHI CME summary (R. Howard, A.
    Vourlidas)
  • -links with other web sites

  • Radio imaging at 164 Mhz
  • traces the CME development and the regions of B
    interaction
  • The coronal wave and the CME encompasses most
    of the
  • solar disk

164 MHz
  • Electrons trace the expansion of
  • the arch system(2500 km/sec)
  • Coronal wave develops along
  • flank of CME In lateral expansion
