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 073 Välja antud 2200Z kuni 13 Mar 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 12-2100Z kuni 13-2100Z Solar activity increased to high levels. Region 1429
(N18W62) produced a long duration M7 flare at 13/1741Z associated
with Type II and IV radio sweeps (estimated velocity 1366 km/s), a
1400 sfu Tenflare, and an assymetric-halo CME (plane-of-sky velocity
1375 km/s) with a mostly northwest trajectory. The geoeffectiveness
of this CME is currently under evaluation.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate with a slight chance for an X-class flare until Region
1429 rotates off the visible disk on 15 March. Day 3 (16 March)
solar activity is expected to decrease to low levels with a slight
chance for isolated moderate activity.
IIA. Summaarne geofüüsikaline aktiivsus 12-2100Z kuni 13-2100Z
The geomagnetic field was quiet to unsettled. The greater than 10
MeV and greater than 100 MeV protons became rapidly enhanced just
after the M7 flare with associated CME. The greater than 10 MeV
event began at 13/1810Z, reached a maximum flux of 469 PFU at
13/2045Z and is decreasing. The greater than 100 MeV event also
began at 13/1810Z, reached a maximum flux of 18.9 PFU and is also
decreasing. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels during the period.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic activity is
expected to be at quiet levels on days one and two (14 and 15
March). Activity is expected to increase to quiet to unsettled
conditions on day 3 (16 March) due to a recurrent coronal hole
high-speed stream.
