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 179 publicerat klockan 2200Z på 27 Jun 2012IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z Solar activity was low. Regions 1512 (S15E11) and 1513
(S15E58) each produced low-level C-class flares as well as
occasional optical subflares. Region 1512 showed spot and penumbral
growth in its intermediate portion along with an increase in
magnetic complexity and was classified as a Dki/beta-gamma. Region
1513 showed a minor increase in spot count during the period and was
classified as a Cso/beta. New Regions 1514 (S16E55) and 1515
(S16E70) were numbered and were classified as a Bxo/beta and
Cso/beta, respectively. Region 1515 produced occasional optical
subflares during the latter half of the period. No Earth-directed
coronal mass ejections were observed during the period.
IB. Prognos för solaktivitet
Solar activity is expected to be low
through the period (28 - 30 June) with a chance for an M-class
flare.
IIA. Sammanfattning av geofysisk aktivitet 26-2100Z till 27-2100Z
The geomagnetic field was quiet with unsettled to active periods
detected at high latitudes.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet on day 1 (28 June). Field activity is expected
to increase to quiet to unsettled levels on day 2 (29 June) with a
chance for active levels due to the arrival of a co-rotating
interaction region in advance of a coronal hole high-speed stream
(CH HSS). A further increase to unsettled to active levels is
expected on day 3 (29 June) with a chance for minor storm levels due
to CH HSS effects.
