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 165 publicerat klockan 2200Z på 14 Jun 2011IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity was at low levels during the period. New
Region 1236 (N17E64) rotated onto the disk as a D-type spot group
and produced two low-level C-class events. A north-south oriented
filament channel, located near the SE limb, erupted during the
period. SDO/AIA 193 imagery revealed material movement along the
large channel, first visible at 14/0609Z, and movement continued
through about 14/1500Z. Associated with the filament eruption was a
partial halo CME off the east limb, first visible in STEREO-Behind
COR2 imagery at 14/0810Z. A plane-of-sky velocity was estimated at
about 750 km/s. This CME does not appear to be Earth-directed.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels with a slight chance for an M-class event all three days
of the forecast period (15 - 17 June).
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field was at quiet to unsettled levels with an
isolated active period observed between 14/0900 - 1200Z. This
activity was due to continued effects from a recurrent coronal hole
high speed stream. During the period, solar wind velocities rose
steadily from near 450 km/s to about 550 km/s. The Bz component of
the interplanetary magnetic field varied between +/- 8 nT while Bt
varied between 5 and 10 nT. The greater than 10 MeV proton
enhancement, present since 11 June, decayed to background levels
early on 14 June.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels for day one (15 June),
with a chance for active levels due to continued high speed stream
effects. Activity is expected to decrease to mostly quiet levels on
days two and three (16 - 17 June) as high speed stream effects
subside.
