Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 150 Issued at 2200Z on 29 MAY 2000IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z SOLAR ACTIVITY WAS VERY LOW. ONLY A FEW FLARES OCCURRED
AND ALL WERE BELOW C-LEVEL. REGION 9017 (S13E16) REMAINS THE MOST
COMPLEX SUNSPOT GROUP ON THE VISIBLE DISK. REGIONS 9023 (S03W12) AND
9024 (S14E55) WERE NUMBERED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 9017 IS THE MOST LIKELY SOURCE OF FLARE
ACTIVITY.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MINOR STORM LEVELS. THE
GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS
MODERATE.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE DUE TO CORONAL HOLE RELATED
ACTIVITY.
