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 288 Välja antud 2200Z kuni 15 Oct 2010IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z Solar activity remained at very low levels. Regions
1112 (S19W15), 1113 (N17E50), and newly numbered 1115 (S28E63) each
produced isolated low-level B-class flares. Regions 1113 and 1115
were both H-type spots and exhibited no significant changes. Region
1112 showed minor spot growth during the period. A slow CME
(estimated plane-of-sky velocity 140 km/s) was evident in SOHO and
STEREO coronagraph images - first visible in SOHO/LASCO C2 at
14/1348Z. The CME had a northwestward trajectory and is not expected
to be geoeffective.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low through the period (16 - 18 October).
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
Geomagnetic field activity was at quiet levels. However, ACE solar
wind data indicated a CME passage around 15/0300Z, likely associated
with the filament eruption observed on 10 October. Solar wind
changes associated with the CME passage included increased
velocities (277 to 354 km/s), increased IMF Bt (peak 09 nT at
15/0919Z), and intermittent periods of southward IMF Bz (maximum
deflection -07 nT at 15/1725Z).
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to be at quiet to unsettled levels, with a slight chance
for active levels, on day 1 (16 October) as the CME passage
continues. Activity is expected to decrease to quiet levels during
days 2 and 3 (17 - 18 October).
