Capabilities of coordinated white-light and radio wave observations

Explore the capabilities of coordinated white-light and radio wave observations for studying solar activities like coronal mass ejections and electron beams. Discover a new web platform for radio monitoring. The site will provide valuable data on CMEs, onset, and development, excluding microwave but focusing on dm-km data. Gain insights into fast narrow and wide CME events and radio sources spread. Utilize radio imaging at 164 MHz to track CME development and solar disk interaction. Follow the expansion of arch systems and more through weekly image deliveries and other radio spectrographs.

  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 monitoringM. 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
