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 18 Jun 2012IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z Solar activity was low. Region 1504 (S15W53) produced
a few low level C-flares, the largest of which was a C1/Sf at
17/2139Z. Region 1504 decreased in total area and ended the day at
690 millionths. Regions 1505 (S13W53) and Region 1506 (N08W42)
showed signs of decay. There were no Earth-directed CMEs observed
during the period.
IB. Prognos för solaktivitet
Solar activity is expected to remain
low with a chance of isolated M-class activity from Region 1504.
IIA. Sammanfattning av geofysisk aktivitet 17-2100Z till 18-2100Z
The geomagnetic field ranged from quiet to minor storm levels.
Active levels were reached at the beginning of the period from
17/2100Z to 18/0300Z. Minor storm levels were reached from 18/0300Z
to 18/0600Z. This elevated activity was due to persistent effects
from the 13 and 14 June CMEs. The remainder of the period showed a
steady decline to mostly quiet levels. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be quiet to unsettled on day 1 (19 June). Quiet levels
are expected on 20 - 21 June.
