A great night - the first SDI observations with the new intensified CCD detector! Kp reached 6. The winds look like a typical expanded convection pattern. Winds reached perhaps 400 m/s by magnetic midnight. Not much spatial structure though. SDI obs at 8 and 4 minute time resolution. Updated, 05-01-98, 06:00 UT, MPK.
