Highlights of Solar and Geomagnetic Activity
02 - 08 March 2026
Solar activity was at low levels with a total of 24 C-class flares
observed. The largest flares of the period were observed early on 02
March; a C6.1 flare at 02/0206 UTC from Region 4380 (S20, L=195,
class/area Dao/140 on 26 Feb) and a C5.2 at 02/0615 UTC and a C 5.9
at 02/ 0749 UTC, both from Region 4381 (N08, L=173, class/area
Eao/220 on 03 Mar). Region 4384 (N10, L=150, class/area Eho/300 on
03 Mar) was the most active, producing 10 weak C-class events. No
Earth-directed CMEs were observed in available LASCO imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 02, 03 and 08 Mar with a peak flux of 10,450 pfu
observed at 02/1810 UTC. Normal to moderate levels were observed on
04-07 Mar.
Geomagnetic field activity reached quiet to G1 (Minor) geomagnetic
storm levels during the period. Quiet levels were observed on 02 Mar
through midday on 03 Mar. Unsettled to G1 (Minor) storm levels were
observed on the last half of 03 Mar into early 04 Mar due to effects
from a positive polarity CH HSS. Quiet to isolated unsettled levels
were observed on a majority of 04 Mar through 06 Mar. Negative
polarity CH HSS effects influenced 07-08 Mar with quiet to active
levels observed on the 7th and quiet to G1 (minor) storms observed
on 08 Mar.
Solar wind parameters observed a peak wind speed of about 675 km/s
late on 07 Mar. Total field reached peaks of 11 nT on 03 Mar and 12
nT midday on 07 Mar, while Bz was southward to -10 nT late on 03 Mar
and -9 nT late on 06 Mar. Phi angle was in a mostly positive
orientation on 02 Mar through midday on 06 Mar and in a negative
orientation from midday on 06 Mar through 08 Mar.
Forecast of Solar and Geomagnetic Activity
09 March - 04 April 2026
Solar activity is expected to be at low levels, with a slight chance
for M-class (R1-R2/Minor-Moderate) flares throughout the outlook
period. Elevated probabilities are related to the flare potential of
both currently observed spot groups as well as the potential from
returning regions.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels on 09-11, 16-19, 23-30 Mar and 04 Apr
due to the influence from multiple, recurrent, CH HSSs. The
remainder of the outlook period is likely to be at normal to
moderate levels.
Geomagnetic field activity is expected to reach G1 (Minor)
geomagnetic storm levels on 14 Mar, 22 Mar, 25 Mar and 03-04 Apr
during the onset CH HSS. G2 (Moderate) geomagnetic storm levels are
likely on 21 Mar due to negative polarity CH HSS effects. Unsettled
to active levels are likely on 09-11, 15-20, 23-24, 26-28, 30 Mar
and 02 Apr. All elevated levels of geomagnetic activity are
associated with the anticipated influence of multiple, recurrent, CH
HSSs. The remainder of the outlook period is likely to be at mostly
quiet levels.
