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 212 Välja antud 2200Z kuni 30 Jul 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity was moderate. Region 1532 (S19E14) and
new Region 1536 (S21E26) were responsible for the highest flares
during the period: a C8/1n flare at 30/1403Z and an M1/Sn at
30/1548Z respectively. Analysis with magnetogram and white light
imagery determined that Region 1532 was actually two separate
regions. New Region 1536 now encompasses the two larger spots
trailing Region 1532. Another new spot group rotated onto the
northeast limb and was numbered Region 1535 (N18E64). No
Earth-directed coronal mass ejections were observed during the
reporting period.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a chance for M-class flares. Regions 1532 and 1536 are the
most likely Regions to produce M-class activity.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
The geomagnetic field was quiet to active with intervals of minor to
major storming observed at high latitudes during the periods ranging
from 30/0600 - 0900Z and from 30/1200 - 1800Z. Solar wind speed,
measured at the ACE spacecraft, increased from approximately 350 to
450 km/s, while the Bz component of the interplanetary magnetic
field had prolonged southward intervals near -7 nT.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled on day 1 (31 July). Mostly quiet
conditions are expected on day 2 (01 August). By approximately
mid-day on day 3 (02 August), quiet to unsettled conditions are
expected with isolated active periods possible due to effects from
the 28 July CME.
