Solar activity was at very low levels. The LASCO/C2 coronagraphic images now clearly indicate that the coronal mass ejection (CME) associated with yesterday's (20 February) filament eruption had no earth-directed component. A new eruption/restructuring of the filament, located near N10W12, started around 08:00 UT and was still in progress. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Around 14UT, the solar wind speed started a gradual increase from 300 km/s to its current values near 450 km/s (DSCOVR) in response to the arrival of the co-rotating interaction region (CIR) and wind stream associated with the positive polarity coronal hole (CH). Bz oscillated between -8 and +10 nT. The interplanetary magnetic field was directed away from the Sun (positive sector) for the second half of the period. Geomagnetic activity was at quiet to unsettled levels, with Kp recording an isolated active period during the 06-09UT interval.

Mostly quiet to unsettled geomagnetic conditions are expected in response to the wind stream from the positive polarity CH, with an isolated active episode remaining possible.
