Sluneční záblesky : C-class flares expected, (probability >=50%)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : Solar flaring activity remained at moderate levels over the past
24 hours with an M2.9-class flare, peak time 13:06 UTC on Jan 27th by NOAA
AR 3192 from behind the west limb. Multiple low C-class flaring was
produced by NOAA AR 3202 (beta) with isolated flaring from NOAA AR 3199
(alpha) and NOAA AR 3196 (beta). Further low levels of activity were
produced by regions behind the east limb. All regions on the visible solar
disc are small, magnetically simple and have either exhibited some decay or
remained stable. The solar flaring activity is expected to be mostly at low
levels over the next 24 hours with possible isolated M-class flaring and
minor chance for an X-class flare.
No Earth-directed coronal mass ejections (CMEs) were detected in the
available coronagraph imagery over the past 24 hours.
The greater than 10 MeV proton flux was at nominal levels in the past 24
hours and is expected to remain so in the next 24 hours. The greater than 2
MeV electron flux has been below the1000 pfu threshold and is expected to
remain so. The 24h electron fluence was at nominal levels and is expected
to remain so over the next 24 hours.
Over the past 24 hours the solar wind conditions (ACE and DSCOVR) were
indicative of a mild high speed stream. The solar wind velocity varied
between 463 km/s and 584 km/s. The interplanetary magnetic field reached
9.8 nT with a minimum Bz of -7 nT. The B field was predominantly in the
positive sector (directed away from the Sun). The solar wind parameters are
expected to remain enhanced over the next 24 hours under the continuous
mild influence of a high speed stream arrival from a positive polarity
coronal hole.
The geomagnetic conditions over the past 24 hours were quiet to unsettled.
Mostly quiet to unsettled conditions are expected over the next 24 hours
with possible active periods and a minor chance for an isolated minor
storm.
