  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

  3. Fast narrow CME 12 December 02 ~1500 km/s NRH 12:36-12:40 UT Cadence10s, 1s Solar soft

  4. 12 December 2002

  5. 28 October 2003 WAVES DAM W E NRH N S

  6. Fast wide CMEs On-Disk development DAM 28 October 2003 W NRH E N S Radio sources spread, suggest a disturbance V ~2500 km/s 24events (NRH observing time 1996-2000)spreading (May 02 1998, association with Moreton wave, Pojholainen et al., 2001, ApJ))

  7. Heliograph Ha « l variable » de Meudon Cadence 1 mn with 3 l Intensitycenter of line Running differences 28 Octobre 2003

  8. October 28 2003 Onde de Moreton et CMEs RH Nançay C2 LASCO • 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

  9. 164 MHz • Electrons trace the expansion of • the arch system(~2500 km/sec) • Coronal wave develops along • flank of CME In lateral expansion

  10. Radio CMEs

  11. Web page

  12. Concluding remarks • Weekly deliver • NRH clean images • Image 10 ko • Work • S-Waves • Other radio spectrographs ? • Survey (composite) 1997-to-day
