EVENT SUMMARY
From Chris St.Cyr (SOHO/LASCO)
There have been multiple CMEs above the NNW limb, apparently associated
with the soft X-ray events of the past 24 hours. At least two of the CMEs
had extensions that were >120 degrees putting them in the partial halo category.
Further, there has been a quasi-continuous "CME" of rising, evolving arcades in
the SW during this same period. The size of these CMEs is large and they are
clearly from the front-side (as evidenced in EIT images).
Space Weather Outlook from SEC/NOAA
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
ADDITIONAL C-CLASS EVENTS ARE LIKELY FROM REGION 8203.
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED EARLY IN THE INTERVAL, THEN QUIET BY 19
APRIL. A RECURRENT HIGH-SPEED STREAM SHOULD ELEVATE ACTIVITY TO A
SLIGHT DEGREE ON 17 APRIL.
