SIDC SOLAR BULLETIN 14 Aug 2022, 1233UT
SIDC FORECAST (valid from 1230UT, 14 Aug 2022 until 16 Aug 2022)
SOLAR FLARES  : C-class flares expected, (probability >=50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 14 Aug 2022  10CM FLUX: 126 / AP: 007
PREDICTIONS FOR 15 Aug 2022  10CM FLUX: 127 / AP: 007
PREDICTIONS FOR 16 Aug 2022  10CM FLUX: 124 / AP: 007
COMMENT: Solar flaring activity was at low levels. Several C-flares
occurred in the past 24 hours, the majority of which originated from NOAA
active regions 3079 and 3081. The strongest flare was a C6.7 flare from
NOAA AR 3079 peaking at 13:00 UTC. NOAA ARs 3080 and 3074 have decayed into
plage regions. NOAA AR 3081 has developed rapidly in the north-west of the
solar disk, the remaining active regions are relatively simple and stable.
Solar flaring activity is expected to be a low levels, with C-class flaring
very likely and a chance for M-class flaring.

No Earth-directed coronal mass ejections (CMEs) were detected in the
available coronagraph imagery.

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 days. The greater than 2 MeV
electron flux was above the 1000 pfu threshold and is expected to be above
or around the threshold in the next 24 hours. The 24h electron fluence was
at moderate levels and is expected to be at moderate levels with a slow
decreasing trend.

The Earth continues to be under the waning influence of a high-speed
stream. The solar wind speed decreased from around 540 to 470 km/s, while
the interplanetary magnetic field strength varied around 5nT. The magnetic
field orientation showed mostly a connection to a positive sector (field
away from the Sun). Over the next 24 hours solar wind speed is expected to
continue the decreasing trend and slowly return towards slow solar wind
conditions/

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp
1-3). Geomagnetic conditions are expected to be quiet to unsettled over the
next days.

TODAY'S ESTIMATED ISN  : 123, BASED ON 19 STATIONS.
