Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 305 Välja antud 2200Z kuni 01 Nov 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 31-2100Z kuni 01-2100Z Solar activity was low. Newly numbered Region 1338
(S12E69) produced the largest flare of the period; a C5 flare at
31/2322Z. Another new region, responsible for M-class flare
activity on 31 October, is currently rotating into view on the
Northeast limb and was numbered Region 1339 (N22E71). A CME was
observed in SOHO/LASCO C2 imagery at 31/1700Z with the majority of
the ejecta off the Northeast limb. The CME was associated with a
disappearing solar filament (DSF) that was observed in SDO/AIA 193
imagery at 31/1426Z. STEREO B COR 2 imagery had a plane of sky
speed of approximately 503 km/s. A glancing blow from this CME is
possible early on 04 November.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. Further M-class flares are likely from new Region
1339.
IIA. Summaarne geofüüsikaline aktiivsus 31-2100Z kuni 01-2100Z
The geomagnetic field ranged from quiet to minor storm levels with
major and severe storm periods observed at high latitudes. At
approximately 01/0817Z, a shock arrival was observed at the ACE
spacecraft. Solar wind speed increased from approximately 370 km/s
to 420 km/s while the total magnetic field (IMF Bt) increased from 5
to 15 nT. A sudden impulse (SI) of 18 nT was observed on the
Boulder magnetometer at 01/0907Z. This event was possibly due to
transient activity associated with a DSF on 28 October.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods
possible on day 1 (02 November) due to continued activity from
transient activity on 01 November. Mostly quiet conditions are
expected on days 2 - 3 (03 - 04 November).
