LASCO CME List Coronal Mass Ejections (CMEs) are massive (10^14
to 10^17 grams) bursts of plasma that are ejected from the sun.
One of the scientific objectives of LASCO is to understand why
these events occur. We believe that they are caused by
instabilities in the solar magnetic field, which is constantly
evolving. Another scientific objective is to understand what
effects CMEs have in interplanetary space and very importantly
what effects CMEs have when they encounter the earth's
environment. We know that the energetic CMEs will cause
geomagnetic storms and possibly affect electric power
transmission lines. A preliminary list of events has been
generated. This is not necessarily complete, but should contain
all of the biggest events. The list is divided by year. Dr.
Chris St.Cyr has completed updating the preliminary
1/1996-6/1998 lists by more detailed analysis of CMEs detected
in the LASCO C2/C3 images. These lists are provided for
researchers with complementary data who wish to collaborate with
members
