In the last 24 hours Solar activity reached moderate levels following a long-duration M1.1 flare at 20 to 1948 utc from Region 3897 as it transitedthe west limb. This region also produced the majority of the C-classflare activity during the period. Region 3898 exhibited slight decay early in the period, but then had someredevelopment later and managed to produced a C3.5 flare at 20 to 0632 utc. Region 3901 added a pair of low-level C-classflares, but remained mostly unchanged. The remaining regions werequiescent. New Region 3902 was numbered. Whileseveral coronal mass ejections were observed in SOHO to LASCO coronagraph imagery, none weredeemed Earth-directed. Solar activity is expected to be low, with a chance for M-class flares and a slight chance of X-class events 21 to 23 november.

In the last 24 hours The greater than 2 mega electron volt electron flux was normal to moderate and thegreater than 10 mega electron volt proton flux was at background levels. The greater than 2 mega electron volt electron flux is expected to continue at normalto moderate levels and the greater than 10 mega electron volt proton flux is expectedto maintain background levels on 21 to 23 november.

In the last 24 hours Solar wind parameters reflected a weakly enhanced solar wind regimeearly, before transitioning to background levels the latter half of theperiod. Solar wind speeds ranged between 350 kilometers per second to 400 kilometers per second. Totalfield strength averaged near 10 nano tesla, reached a peak of 13 nano tesla, thendecreased to remain near 5 to 8 nano tesla the last half of the period. The Bzcomponent fluctuated between +9 to to 10 nano tesla before turning mostly north, andthe phi angle was predominantly in a positive orientation. Solar wind conditions are anticipated to become elevated on 22 to 23 Novdue to negative polarity coronal hole high speed stream influences.

In the last 24 hours The geomagnetic field was quiet to unsettled. The geomagnetic field is expected to be mostly quiet on 21 Nov, becoming quiet to unsettled, with a chance for an isolated activeperiod, on 22 to 23 Nov, due to anticipated coronal hole high speed stream effects.
