Bulletin

NOAA 2567 produced all 7 C-class flares observed during the period, the strongest being a C9.1 peaking at 12:55UT. NOAA 2567 has decreased somewhat in sunspot area and magnetic complexity. NOAA 2565 was quiet. No earth-directed coronal mass ejections (CMEs) were observed. A substantial CME first seen by LASCO/C2 at 02:48UT was related to a backside event.

C-class flaring is expected, with a chance on an M-class flare.

Solar wind speed decreased from 430 to 380 km/s. Bz gradually turned negative, from an initial +8 nT to -5 nT at the end of the reporting period. The interplanetary magnetic field was directed towards the Sun (negative). A positive coronal hole (CH; latitude +20 degrees) will start its central meridian transit later today. Quiet to unsettled geomagnetic conditions were observed.

Mostly quiet to unsettled geomagnetic conditions are expected. Active episodes are possible in response to the high speed stream of the negative northern coronal hole, and from a possible glancing blow of the 21 July CME later today or on 23 July. A minor storming episode is not excluded.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 043, na základě 25 stanic.
