Bulletin

The two currently visible sunspot groups are gradually declining. A small active region is just behind the southeast limb. No C-class flares or earth-directed coronal mass ejections (CMEs) were observed.

Quiet flaring conditions are expected, with a small chance on an isolated C-class flare.

Solar wind speed gradually declined to its current values between 340 and 360 km/s, as Earth exited the moderate-speed stream from the trans- equatorial coronal hole (CH). Bz has been oscillating mostly between -7 and +7 nT. Quiet to unsettled geomagnetic conditions have been recorded. A positive CH between latitude 25 to 40 degrees north is transiting the central meridian and may affect the geomagnetic field starting 25 July.

Quiet to unsettled geomagnetic conditions are expected, with a chance on an active geomagnetic episode in response to the possible glancing blow from the 19 July CME.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 039, basierend auf 18 Stationen.
