In the last 24 hours Solar activity remained at low levels with Region 4465 being the source of the largest events of theday: a long-duration C6.7 to 1 f flare observed at 11 to 0002 utcand an impulsive C9.0 flare at 11 to 0828 utc. The C6.7 to 1 f flare wasaccompanied by Type-II and Type-IV radiobursts, and a partial halo coronal mass ejection Earth-directed. The coronal mass ejection analysis indicated potential impact near-Earth starting early on 13 june. No other Earth-directed coronal mass ejections were observed in availablecoronagraph imagery. Solar activity is expected to remain at low levels through 14 June, witha high chance for M-class flares and a slightchance for X-class flares , mostly due to the flare potentialof Region 4465.

In the last 24 hours The greater than 2 mega electron volt electron flux at geosynchronous orbit continuedat low to moderate levels. The greater than 10 mega electron volt proton flux atgeosynchronous orbit remained at background levels. The greater than 2 mega electron volt electron flux is expected to remain at low tomoderate levels on 12 June, before rising to high levels on 13 to 14 Junein response to the high-speed stream effects. The greater than 10 mega electron voltproton flux is expected to remain at background levels through 14 June.

In the last 24 hours Solar wind parameters indicated the arrival of the anticipatedcorotating interaction region around 11 to 1700 utc, with theincrease of the speeds and enhancement oftotal interplanetary magnetic field strength from 5 nano tesla to 15 nano tesla at theend of the period. Two sustained periods of Bz negative were observed:between 11 to 0350 to 0955 utc and between 11 to 1835 to 2100 utc. The later event, associated with the increased speeds and densities from the CIR, resulted in a minor geomagnetic storm. The phi angle becamepredominantly oriented in the negative sector after 11 to 1600 utc. Solar wind enhanced disturbances are expected to persist on 12 June, asthe high speed stream associated to a negative coronal hole brings faster solar wind speeds to the Geospace. Elevated solar windconditions are expected to persist through 13June, around which time additional disturbances are likely, due tocombining coronal mass ejection influences from the eruptions that departed the Sunday on 09June and 11 June.

In the last 24 hours The geomagnetic field was at quiet to minor storm levels as a result ofa sustained southward Bz upon the arrival of the anticipated CIRnear-Earth. Geomagnetic field conditions are expected to reach G1 geomagnetic storming on 12 June under anticipated -coronal hole high speed stream effects. G2 geomagnetic storming levels are likely on 13 June due to thepersistence of the high-speed stream and the arrival of the disturbancescaused by the coronal mass ejections that left the Sunday on 09 and 11 June. G1 levels are likely on 14 June, as the coronal mass ejections effects wane.
