Bülletään

Solar activity has been low, only one C-class flare in past 24 h: a C1.2 flare that peaked at 10:47 UT from NOAA AR 2539 (Catania 66 and 67). 6 active regions are visible on the disk, 4 of them with beta magnetic field configuration, C-class flaring is likely.

Geomagnetic conditions have been quiet. Solar wind speed is currently at 350 km/s with interplanetary magnetic field magnitude of 7 nT. A sector boundary crossing from positive to negative polarity was observed at ACE around 03:00 UT, marking the upcoming arrival of an expected fast speed stream from a coronal hole. Currently two coronal holes are in Earth- affecting position, one in the northern hemisphere and one at the equator, both have negative polarity. Up to minor storm conditions are expected for today and tomorrow.
