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 029 publicerat klockan 2200Z på 29 Jan 2001IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z Solar activity has been low. Newly numbered Region
9329 (S10E50) produced the only notable activity of the day, a C5/Sf
event at 29/1540 UTC. Lesser, uncorrelated C-class activity also
occurred throughout the period. Region 9321 (S03W57) remains the
largest region on the disk, though somewhat reduced in white light
area since yesterday, currently in an Eai Beta configuration. Other
active regions are little changed from yesterday.
IB. Prognos för solaktivitet
Solar activity is expected to be
predominantly low, with a chance of isolated moderate-level activity
possible from Region 9321, or Region 9313 (S04W79) as it rotates
behind the west limb.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
Geomagnetic field activity ranged from quiet to minor storm levels.
An isolated period of minor storming was observed at Boulder during
29/0000-0300 UTC, followed by a single active period thereafter.
The greater-than-10 MeV proton event which began last period has
persisted throughout the day, reaching a maximum flux value of 49
pfu at 29/0655 UTC. An associated polar cap absorption event was
reported for the period of 29/0649-1600 UTC, with maximum absorption
of 1.9 decibles on the Thule 30Mhz riometer. The proton event
remains in progress at the end of period, with a value of about 12
pfu.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be at mostly quiet to active levels during the first
day. Shock arrival from the CME activity of 28 January is expected
to arrive on mid-to-late day one, with isolated minor storming
possible through day two. Activity is expected to taper off
to mainly unsettled levels by day three. The proton event
currently in progress is expected to end during day one.
