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 141 publicerat klockan 2200Z på 21 MAY 1997IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z SOLAR ACTIVITY BECAME MODERATE. REGION 8040 (N06W12)
PRODUCED AN M1/1N (OPTICAL ESTIMATED) AT 21/2015Z. MODERATE
INTENSITY TYPE II, IV, AND CENTIMETRIC BURSTS ACCOMPANIED THE EVENT.
AN OPTICALLY UNCORRELATED C4 FLARE WAS DETECTED AT 20/2210Z AND
REGION 8040 PRODUCED A C2/SF FLARE AT 21/0625Z. REGION 8040
EXHIBITED GROWTH DURING THE PERIOD AND A WEAK DELTA MAY BE FORMING
IN THE TRAILER. A NEW REGION EMERGED NEAR N02E01 AND WAS NUMBERED AS
REGION 8045.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE LOW TO
MODERATE. SHOULD GROWTH CONTINUE IN REGION 8040, C-CLASS AND SMALL
M-CLASS FLARES WILL BECOME MORE FREQUENT.
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT REACHED HIGH LEVELS DURING THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT TWO AND A HALF DAYS.
ACTIVE TO MINOR STORM CONDITIONS ARE FORECAST FOR THE LATTER HALF OF
24 MAY AS A RESULT OF THE EVENT MENTIONED ABOVE. ENERGETIC ELECTRON
FLUXES SHOULD DROP BACK TO BACKGROUND LEVELS WITHIN 48 HOURS.
