In the last 24 hours Solar activity was at low levels. Region 4115 produced a C5.0 flare at 23 to 1223 utc, which was the largest event of theperiod. Regions 4117 and 4118 remained the largest spot groups on the visible diskwith the latter developing a weak gamma configuration. Regions 4119 , 4120 and 4121 all emerged relatively rapidly this period, were numbered, but wereotherwise unremarkable. New, simple spots were also noted near N16E54, but remain unnumbered at this time given a lack of development. NoEarth-directed coronal mass ejections were observed in available coronagraph imagery. A chance for R1-R2 radio blackouts, with a slightchance for X-class flares , will persist through 26June.

In the last 24 hours The greater than 2 mega electron volt electron flux reached high levels with a peakflux of 1, 270 pfu at 23 to 1520 utc. The greater than 10 mega electron volt proton fluxwas at background levels. The greater than 2 mega electron volt electron flux is expected to reach moderatelevels through 26 June with a chance for high levels on 24 June. Thereremains a slight chance for the greater than 10 mega electron volt protons to becomeelevated through 26 June primarily due to the eruptive potential ofRegions 4114 and 4115 as they transit the western limb followed byRegions 4117 and 4118 rotating into a favorable geoeffective location.

In the last 24 hours Solar wind parameters continued to reflect a positive polarity coronal hole high speed streamregime. Total field ranged 3 to 7 nano tesla and the Bz component was + to to 5 nano tesla. Solar wind speeds gradually decreased from ~500 kilometers per second to near 400 kilometers per secondover the course of the period. Phi was predominantly in the positivesolar sector. Gradually waning positive polarity coronal hole high speed stream influence is expected tocontinue on 24 June. An enhanced solar wind regime is expected to returnon 25 June and continue into 26 June due to recurrent, negative polaritycoronal hole high speed stream onset.

In the last 24 hours The geomagnetic field was at quiet to unsettled levels. The geomagnetic field is expected to be at quiet to active levels on 24June under diminishing positive polarity coronal hole high speed stream effects. G1-G2 geomagnetic storming is likely 25 to 26 June due torecurrent, negative polarity coronal hole high speed stream effects.
