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
