R1-R2 Radio Blackouts on 4 September, 2017
R1-R2 (Minor-Moderate)
radio blackouts have occurred on 4 September, 2017; with NOAA/SWPC
Region 2673 the source of the events. RGN 2673 is a magnetically complex
and compact sunspot group that has produced numerous C-class flares and
occasional M-class flares on 4 September; the largest thus far was an
M5 (R2-Moderate) event at 2033 UTC (1633 ET). Sunspot RGN 2674 is not as
magnetically complex and has been relatively inactive. However, due to
the development of mixed polarities within RGN 2673, its
continued growth, and activity trends, the forecast now calls
for expected R1-R2 events the remainder of 4 September on into 5
September. Keep checking our SWPC webpage for the latest forecasts and
alerts.
