In the last 24 hours Solar activity was moderate with multiple M-class flares. Background X-ray flux was at C-class levels and six designated sunspotgroups were present on the visible solar disk. The most notabledevelopment was areal growth in Region 3679 and the emergence of a delta. This region produced themajority of the activity during the period including the largest flare, an M4.2 flare at 23 to 0216 utc. Region 3683 rotated beyondthe limb, but still managed a C9.7 flare at 23 to 0642 utc. Region 3685 exhibited decay in its intermediate spots. Anew area of potential spot emergence was noted at approximately N20W44, but we are awaiting duration requirements before designation. The restof the spotted regions were mostly inactive. There were two filament eruptions that lifted off the SE. The first oneis first visible in C2 imagery at 23 to 0125 utc. Modeling results showed amiss south and behind Earths orbit. The second originated from justeast of AR 3685 and is first visible in C2 at 23 to 0648 utc. Modeling isunderway for this event at the time of this writing. Solar activity is likely to remain moderate 23 to 25 May, with a slightchance of X-class flares due primarily to the increasingflare potential of Region 3679.

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 remained at background values. Normal to moderate levels, with a chance for high levels is forecast for 23 to 25 May, while the greater than 10 mega electron volt proton flux is expected tocontinue at background levels. However, there remains a slight chance ofan S1 solar radiation storm due to the potential from Region 3679.

In the last 24 hours Solar wind parameters were slightly enhanced. Total field was primarily 6 to 8 nano tesla, with a peak of 9 nano tesla and the Bz component was variable. Solarwind speed was below 400 kilometers per second. The phi angle was primarily positive. The mildly enhanced IMF is expected to continue on 23 may. Influencesfrom an isolated coronal hole high speed stream are anticipated on 24 to 25 may. However, most ofthe HSS will likely be north of Earth and mainly modest solar wind speedincreases are expected.

In the last 24 hours The geomagnetic field was quiet. The geomagnetic field is expected to be mainly quiet, with isolatedunsettled conditions on 23 may as the minor enhancement in the solarwind continues. coronal hole high speed stream effects 24 to 25 may may lead to additionalunsettled periods, with possible active conditions on 24 may.
