No SOHO data from 21 Dec. 1998 to 5 Feb. 1999

Notes:   First Obs. is time when CME first detected usually in C2 field. A means an Alert issued.

Span is width of CME and in what direction it was first seen or brightest.

Flare is GOES X-ray peak and Ha peak level (top) and onset time (bottom)

DSF is if an Ha filament has disappeared. (Imp.) is obs. importance of disappearance.

Dimming is from Yohkoh or EIT 195 images.

Wave is from D. Meyers EIT list (thru June 1998), or EIT Alert movie.

Shock is the day and hour of an IP shock, usually at WIND (top)

SEP is the day and hour of a solar energetic part. event at WIND (bot.)

Mag. Cl. is a cloud-like structure at WIND or ACE.

FR in this col. means cloud can be fit to an MFI flux rope model.

BDE is from ACE or WIND 3DP lists or plots. HC is ejecta from Cane list. He is enh. 3He from Ho et al.

Storm is peak intensity and day and hour of storm with Dst<-50nT.

Trn. Time is transit time in hrs/days from CME onset time to storm peak time.
