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 343 Välja antud 2200Z kuni 08 Dec 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z Solar activity was low. Several minor C-class X-ray
flares were observed, mostly from Region 9246 as it rotates around
the west limb near S11. Very little change was noted on the existing
six spotted regions. New region 9262 (N13E70) was numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to continue
at low levels. Most activity will likely originate from Region 9246
as it rotates out of view on the SW limb.
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
The geomagnetic field was quiet to active. The field began the period
at mostly quiet to unsettled levels, but predominantly unsettled to
active conditions began at 07/2300Z following the onset of a high
speed coronal hole stream. Current solar wind speed from this large
transequatorial coronal hole is now near 650 km/s.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to continue at mostly unsettled to active conditions
through day one in response to the high speed coronal hole stream.
Minor storming is likely at high latitudes. This disturbance should
subside through day two. Expect quiet to unsettled conditions
thereafter.
