Gigantic Active Region (AR) 2422 covers 800 millionths of a solar disk
and produced the strongest flare of the day, a M7.6 event peaking at
14:58 UT on 28 Sep 2015. This region has been traversing the
geoeffective region of the visible solar disk. It has been producing
short-duration C- and M-class flares, but so far no associated
Earthward-directed Coronal Mass Ejection (CME) has been observed. The
gigantic solar prominence located just to the east of AR 2423 is
rotating beyond the western limb and is no longer considered a major
threat. The Earth is presently immersed in slow solar wind and no
major disturbances are expected to arrive during the next 2-3 days.
The outlook is for quiet to unsettled geomagnetic conditions during
the next 2-3 days. Conditions for HF radio wave propagation are
gradually trending back towards predicted monthly values in response
to increasing solar flux.
