Preliminary 2000 SOHO LASCO Coronal Mass Ejection List (Revised 01-May-2000 -- SPP) N.B. This is a working version of a catalogue of probable coronal mass ejections detected in white light observations of the LASCO coronagraphs. This list is maintained at the SOHO Experimenters' Operations Facility, and it is based on an examination of only quick-look data, which represents a subset of the final LASCO dataset. Questions about this list should be directed to Russ Howard at NRL (howard@cronus.nrl.navy.mil) or to Simon Plunkett of USRA/NRL (plunkett@kreutz.nascom.nasa.gov). Note some changes to lists from previous years: 1) Some smaller events may be left out of the list. As solar activity increases, it is becoming harder to distinguish and keep account of smaller eruptions. Date(s) UT Location Comment 01-Jan-2000 06:54 NE Large looping on limb.
