The long-duration C2.1 flare related to the complex filament eruption in the southwest quadrant peaked on 19 July at 10:40UT and ended at 13:02UT. The bulk of the related coronal mass ejection (CME), first seen in LASCO/C2 imagery by CACTus on 09:48UT, is directed away from Earth. However, a glancing blow from this CME cannot be ruled out and may impact Earth on 22 or early 23 July. At most active geomagnetic conditions are expected. The two currently visible sunspot regions were quiet. No C-class flares or other earth-directed CMEs were observed.

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

Solar wind speed further declined from 300 km/s to 270 km/s around 03:00UT, then increased to its current values between 290-300 km/s. Bz was initially very low, but has been persistently negative from about 03:00UT till 11:00UT, with maximum values near -6 nT. Bz then quickly returned to very low values. The interplanetary magnetic field (IMF) was mostly directed away from the Sun. Quiet to unsettled geomagnetic conditions have been observed.

Mostly quiet to unsettled geomagnetic conditions are expected, but with a chance on an active geomagnetic episode in response to the anticipated arrival of the high speed stream of the positive transequatorial coronal hole.
