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 170 publicerat klockan 2200Z på 19 Jun 2003IA. Analys av solfläcksgrupper och solaktivitet från 18-2100Z till 19-2100Z Solar activity decreased to very low levels. Flare
activity was limited to several B-class flares. Region 386 (S07E30)
lost penumbral coverage over the period although it does retain a
delta magnetic structure in the dominant lead spot. Region 387
(N18E49) grew in both penumbral coverage and magnetic complexity
since yesterday, a gamma structure is now evident in the trailing
portion of the spot group. Newly numbered Region 388 (S03E08)
produced a minor B-class flare early in the period.
IB. Prognos för solaktivitet
Solar activity is expected to be at
moderate levels. Region 386 remains capable of producing an
isolated major flare.
IIA. Sammanfattning av geofysisk aktivitet 18-2100Z till 19-2100Z
The geomagnetic field was at predominantly active levels today.
Minor storm conditions were observed at both middle and high
latitudes between 19/0000 and 0300Z due to the influence of a
recurrent high speed coronal hole stream. The greater than 10 MeV
proton flux exceeded event threshold at 18/2050Z (reached a max of
24 pfu at 19/0450Z), ended at 19/1900Z and after careful review the
event is believed to have been the result of the M6.8 x-ray flare
from June 17. The greater than 2 MeV electron flux reached moderate
levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly unsettled to active levels through
the interval. Minor storm conditions may exist due to a transient
passage during the first half of day one in response to the M6.8
x-ray flare from June 17.
