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 213 Välja antud 2200Z kuni 01 Aug 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 31-2100Z kuni 01-2100Z Solar activity was low during the past 24 hours. Region
1261 (N18W08) produced the largest event of the period a C4/1F flare
at 01/0732Z. Region 1261 has continued to develop in area and
magnetic complexity and is classified as an Fkc type spot group with
a Beta-Gamma-Delta magnetic configuration. Region 1263 (N127E21) has
maintained its Beta-Gamma-Delta classification and produced three
low level C-class events. Region 1260 (N18W36) and Region 1265
(N17W67) remained stable and quiet, while Region 1264 (S23W07) has
decayed to spotless plage.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate with a slight chance for a major event for the next
three days (02-04 August). Region 1261 is the most likely source
for a major x-ray event and has a slight chance to produce an
energetic proton event.
IIA. Summaarne geofüüsikaline aktiivsus 31-2100Z kuni 01-2100Z
The geomagnetic field has been quiet to unsettled. Solar wind data
observed at the ACE satellite indicated that the coronal hole high
speed stream has subsided with wind speeds decreasing from 700 km/s
to about 550 km/s during the past 24 hours. A solar sector boundary
crossing was observed at 1305Z.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be predominately quiet to unsettled on day one (02
August) as the effects of the coronal hole high speed stream
continues to wane. Days two and three (03-04 August) are expected
to be quiet.
