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 357 publicerat klockan 2200Z på 23 DEC 1997IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z SOLAR ACTIVITY WAS VERY LOW. REGION 8124 (S22E40) WAS
GENERALLY QUIET, PRODUCING ONLY MINOR FLARING. THIS REGION HAS MORE
THAN DOUBLED ITS SPOT AREA AND NOW SHOWS AN EKC GROUP OF 27 SPOTS
WITH A COMPLEX BETA-GAMMA-DELTA MAGNETIC CONFIGURATION. REGION 8123
(N18W64) HAS DECAYED INTO A SINGLE AXX SPOT. NEW REGIONS 8125
(N19E41), A SIMPLE BXO SPOT GROUP, AND 8126 (N20E79), AN HHX SPOT
GROUP, WERE NUMBERED TODAY. REGION 8126 IS THE REAPPEARANCE OF OLD
REGION 8113 WHICH PRODUCED FOUR M-CLASS FLARES AND ONE X-CLASS
FLARE.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE, DESPITE THE LACK OF ACTIVITY OVER THE PAST 24 HOURS.
REGION 8124 SHOWS THE BEST CHANCE FOR C-CLASS FLARE ACTIVITY AND A
CHANCE FOR M-CLASS FLARING. THIS REGION MAY ALSO BE CAPABLE OF
PRODUCING ISOLATED X-CLASS ACTIVITY. REGION 8126 IS STILL AN UNKNOWN
DUE TO ITS PROXIMITY TO THE EAST LIMB, BUT APPEARS TO HAVE THE
POTENTIAL FOR C-CLASS ACTIVITY AND ISOLATED M-CLASS FLARING. VIEWING
TOMORROW WILL DETERMINE THE PRESENCE OF TRAILER SPOTS, IF ANY, AND
THE POSSIBILITY OF INCREASED FLARE POTENTIAL.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET AT ALL LATITUDES FOR THE ENTIRE FORECAST
PERIOD.
