Tue Nov 24 10:24:53 EST 2015

Solar flare activity was low on 23 Nov UT and it is expected to remain
low during the next 48 hours. Active Region 2454 produced the largest
flare during the past 24 hours, a long duration C8 event peaking at
02:28 UT. This active region is rotating toward the western limb. The
bulk of the CME associated with the filament eruption on 22 Nov is
propagating toward the east and will miss Earth. However, a faint halo
may arrive at Earth during 25 Nov. The Earth is currently immersed in
slow solar wind with a speed of about 340 km/s. Faster solar wind is
expected to arrive at Earth early on 25 Nov. Geomagnetic conditions
are expected to remain quiet for most of today, 24 Nov. Conditions may
reach active levels during 24-25 Nov due to the arrival of a frontal
disturbance ahead of faster wind and a possible minor CME impact. Even
if a minor geomagnetic storm eventuates, conditions for aurora viewing
will be poor because of a near full moon. Conditions for HF
communication are expected to be near predicted monthly values today,
24 Nov.
