In the last 24 hours Solar activity was at low levels. Region 4095 produced the largest flare of the period, a C2.4 at 22 to 2241 utc. Theregion has the most complex magnetic classification of the front-sidedgroups as a beta-gamma group. Region 4087 underwentdecay and lost its trailer spots. New Regions 4096 and 4097 were numbered this period. All other regionswere either stable or in decay. There have been no Earth-directed coronal mass ejections in available coronagraph imagery. Solar flare activity is expected to remain low as most regions on thedisk are fairly simple in their magnetic complexities. There remains achance for R1-R2 through 25 may.

In the last 24 hours Ongoing influence from the positive polarity coronal hole high speed stream produced high fluxlevels with a peak of 1, 643 pfu recorded at 22 to 1635 utc. GOES to 19 andGOES to 18 have seen fluxes oscillating around the 1000 pfu during theirrespective diurnal maximas. The greater than 10 mega electron volt proton flux has been at background levels. The greater than 2 mega electron volt electron flux will remain at hgih levels through 25 may from the coronal hole high speed stream. The greater than 10 mega electron volt proton flux is expected to remain at backgroundlevels through 25 may.

In the last 24 hours Solar wind parameters reflected persistent coronal hole high speed stream influence. Total fieldhas been between 4 to 9 nano tesla for most of the period while the Bz componentoscillated between +7 to to 5 nano tesla. Solar wind speeds gradually decreased from~575 to ~475 to 500 kilometers per second. Phi was mostly positive. Solar wind parameters will likely continue to see effects from the CHHSS through 25 may with waning influences 24 may. Model guidanceindicates wind speeds will drop from around 520 kilometers per second to 360 kilometers per second duringthis transition. An enhancement of the solar wind is likely on 23 Maydue to a possible glancing blow from the filament eruption that occurredon 17 may.

In the last 24 hours The geomagnetic field has been at quiet levels. Quiet to unsettled conditions are likely through 25 May, with a chancefor active levels, all due to continued effects from a positive polaritycoronal hole high speed stream stream and possible weak effects from arrival of the 17 may coronal mass ejection.
