Possible WIND Magnetic Cloud Events, compiled by Ron Lepping:

Note: This page is slowly being modified to include more images and explanations.
Possible earth-directed CME observed 7 February 1997 (estimated arrival time: 18 UT on the 10th of February)
Yohkoh dimming at CME onset associated with the eruption (from N. Gopalswamy and H. Hudson)

    EIT 304 Å He II June 23-25 1996 Eruptive Filament
    Filament runs East-West and is situated in the northeast


    EIT 195 Å Fe XII Images for June 23 and 25 - is that a slight dimming in 195 where the filament erupted? It's difficult to tell - there is a slight decrease, but it could be the effect of solar rotation and a different line-of-sight. There are no other EIT images available during this period.
