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 125 publicerat klockan 2200Z på 04 May 2012IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z Solar activity has been at low levels for the past 24
hours. The background x-ray levels, as measured by the GOES-15
spacecraft, have shown a gradual increase to C-class levels. This
increase is attributed to a new unnumbered sunspot region rotating
onto the northeast limb. At the time of the report, SDO
intensitygram images showed only a part of this new region. Due to
the limb location, actual sunspot and magnetic classification has
yet to be determined. The other sunspot regions on the disk remained
rather stable for the past 24 hours. A CME, first observed in STEREO
Ahead COR2 imagery at 04/0309Z, was determined to not be Earth
directed.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels with a slight chance for M-class events for the next
three days (05 - 07 May).
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
The geomagnetic field has been at mostly quiet levels for the past 24
hours. Solar wind speeds, as measured by the ACE spacecraft, have
remained at background levels, below 400 km/s.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at mostly quiet levels for the next three days (05 -
07 May).
