[ips-sf] IPS Summary Forecast for 23 November - issued 2345UT/22-Nov-2015 [SEC=UNCLASSIFIED]

[rwc]

Low solar activity observed over the last 24 hours. Today's largest
two flares were a C5.6 flare that peaked at 0538 UT and the other one
a longer duration C5.1 that peaked at 0210 UT, both from the region
2454 (N13W53). Solar wind speed remained stable around 350 km/s during
the UT day today and the Bz component of IMF varied mostly between
+/-4 nT during this period. A seemingly non-earthward directed CME
from the irruption of a long filament in the south east regions of the
solar disk, was seen in the LASCO C2 imagery from around 0900 UT. Low
levels of solar activity may be expected for the next three days with
some possibility of isolated M-class activity. Geomagnetic activity
remained at quiet levels today. Nearly similar conditions may be
expected for the next three days (23, 24 and 25 November) with the
possibility of rise in activity to unsettled levels on 25 November due
to a coronal hole effect. Observed MUF's were mostly near predicted
monthly values today with periods of minor to mild enhancements in low
and mid latitude regions. Nearly similar conditions may be expected
for the next three days (23 to 25 November) with the possibility of
minor MUF depressions and degradations in HF conditions on 25
November, especially in high and mid latitude region, due to a
possible rise in geomagnetic activity levels on this day.
