Highlights of Solar and Geomagnetic Activity
22 - 28 January 2024
Solar activity was at low to high levels this period. High levels
were observed on 22 January with seven R1 (minor) flares observed
from Regions 3559 (N27, L=288, class/area Fki/520 on 23 Jan) and
3561 (S17, L=327, class/area Dac/220 on 23 Jan). The largest of
these flares was an M3.4 from Region 3461 at 22/2121 UTC. On 23
January, nine R1 (minor) and one R2 (moderate) flares were observed
from Regions 3559 and 3561. The largest flare was an R2 (moderate)
M5.1 from region 3559 at 23/0331 UTC. Moderate levels were observed
on 24 January with four R1 (minor) flares observed, the largest an
M2.6 from Region 3561 at 24/0140 UTC. Low levels were observed on
25-28 January. A Type II radio sweep, with a speed of 648 km/s, was
observed at 28/0228 UTC. Location of this was suspected to be from a
region behind the ENE limb.
No 10 MeV proton events were observed at geosynchronous orbit. An
enhancement of 7.14 pfu was observed at 22/1655 UTC, most likely
from R1 (minor) flare activity from Region 3559.
The greater than 2 MeV electron flux at geosynchronous orbit was at
low to moderate levels through the period.
Geomagnetic field activity was mostly quiet with isolated unsettled
and active periods due to weak CME activity on 22-24 Jan and initial
influence from a negative polarity CH HSS late on 28 Jan.
Forecast of Solar and Geomagnetic Activity
29 January - 24 February 2024
Solar activity is expected to be low to moderate
(R1-R2/Minor-Moderate) levels on 29-31 Jan due primarily to the
flare potential of Region 3559. Low levels are expected on 01-11
Feb. An increased chance for moderate (R1-R2/Minor-Moderate) levels
is possible on 12-24 Feb as Region 3559 rotates back onto the
visible disk.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 01-03 Feb due to CH HSS influence.
Low to moderate levels are expected from 28-31 Jan and 04-24 Feb.
Geomagnetic field activity is expected to be at unsettled to
isolated active periods on 29-31 Jan and 05-06 Feb due to recurrent
CH HSS activity. Mostly quiet levels are expected on 01-04 and 07
-24 Feb.
