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.
