Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 146 publicerat klockan 2200Z på 26 MAY 1997IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z SOLAR ACTIVITY HAS BEEN VERY LOW. OCCASIONAL LOW-LEVEL
B-CLASS FLARES WERE OBSERVED DURING THE PERIOD, AS WERE OCCASIONAL
TYPE III RADIO SWEEPS, BUT THERE WERE NO OBVIOUS SOURCE REGIONS FOR
THESE EVENTS. GROUP 8046 (S27E28) CONTINUES TO BE A BIT MORE ACTIVE
THAN THE OTHER TWO SPOTTED REGIONS ON THE DISK AS IT SHOWED
INTERMITTENT BRIGHTENINGS IN H-ALPHA DURING THE DAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
THE GEOMAGNETIC FIELD WAS QUIET FROM 25/2100Z UNTIL 26/1000Z WHEN A
WEAK SUDDEN IMPULSE WAS OBSERVED (THE IMPULSE MEASURED 13 NT IN
BOULDER). FROM 26/1000Z-2100Z ACTIVITY HAS BEEN SLIGHTLY ENHANCED,
RUNNING QUIET TO UNSETTLED AT MIDDLE LATITUDES, AND UNSETTLED TO
SLIGHTLY ACTIVE AT HIGH LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED FOR THE NEXT THREE DAYS.
