Solar activity has been at low levels over the past 24 hours, with three numbered sunspot regions currently on the disk, according to the joint USAF/NOAA Solar Geophysical Activity Report and Forecast issued at 2200Z on 2 October 2026.
Solar activity is expected to remain very low, with a chance for C-class flares on 3, 4 and 5 October, the report said. Event probabilities for M-class flares are 5 percent on each of the three days, while X-class and proton event probabilities are 1 percent.
The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 320 km/s at 0007Z on 2 October, total IMF reached 6 nT at 2335Z on 1 October, and the maximum southward component of Bz reached -4 nT at 0014Z on 2 October. Electrons greater than 2 MeV at geosynchronous orbit peaked at 933 pfu.
The geomagnetic field is forecast to be at quiet to active levels on 3 and 5 October, and at unsettled to minor storm levels on 4 October. The Penticton 10.7 cm flux was observed at 92 on 2 October and is predicted at 92, 90 and 90 for 3 to 5 October, against a 90-day mean of 115.
