Bulletin

The Sun did not produce any flares in the past 24 hours. A Bxo (beta) sunspot region emerged around 15h UT on June 30 near S25E0, but had all but decayed again on July 1, meaning the visible side of the Sun is spotless again. The chance for a C flare in the next 24 hours is estimated at only 1%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by ACE varied between about 300 and 390 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 2 and 9 nT (with values unknown during a data gap from about 3:20 till 10:20 UT on July 1), with current values around 7 nT. Bz had some short intervals below -5 nT between about 23h UT on June 30 and the start of the data gap around 3:20 UT on July 1.

Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 0 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on July 1, 2 and 3, with a chance for active geomagnetic levels (K Dourbes = 4) on July 1 and 2.
