Bülletään

Solar activity was at very low levels. A B1 flare peaking at 21:48UT on 29 July had its source in the spotless faculae field near S08E65. No coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar activity is expected to remain at very low levels.

Solar wind speed gradually declined from about 330 to 275 km/s by 10:30UT, then increased to values around 330 km/s (DSCOVR). Bz varied mostly between -4 and +5 nT, being predominately negative during the first half of the period. The interplanetary magnetic field was mostly directed towards the Sun. Mostly quiet geomagnetic conditions were observed, with unsettled conditions recorded by Dourbes during the 18-21UT and 06-09UT intervals.

Mostly quiet geomagnetic conditions are expected, with a chance on an isolated unsettled episode.
