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 214 Välja antud 2200Z kuni 02 Aug 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z Solar activity was moderate during the past 24 hours.
Region 1261 (N15W21) produced a long duration M1/1N flare at
02/0619Z with associated Type IV, Type II (estimated speed of 1067
km/s), and Tenflare (220 sfu) radio emissions. LASCO C3 imagery
indicated a full halo coronal mass ejection also associated with
this event. Region 1261 maintained its Fkc type spot group
classification and Beta-Gamma-Delta magnetic configuration. Region
1263 ((N17E08) produced multiple C-class events and maintained its
Beta-Gamma-Delta configuration. Region 1260 (N15W21) remained quiet
and stable. Region 1265 (N16W80) was quiet as it began to rotate
off the visible disk.
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 (03-05 August). Region 1261 and Region 1263 are both
capable of producing a major event and both have a slight chance of
producing an energetic proton event.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
The geomagnetic field was quiet during the past 24 hours. Solar wind
data observed at the ACE satellite indicated a decrease in solar
wind speed from 550 km/s to 450 km/s as the effects from the coronal
hole high speed stream waned. The GOES 13 satellite observed an
enhancement of the 10 MeV protons associated with the periods M1
flare.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet on day one (03 August). Day two is expected to
be predominately quiet with chance a for isolated active conditions
late in the day. Day three (05 August) is expected to be unsettled
to active with a chance for minor storm conditions. The increase in
activity is forecast due to the expected arrival of the coronal mass
ejection from 02/0616Z. Due to the enhanced environment there is a
chance for the 10 MeV protons to cross event thresholds with shock
arrival.
