INFO FROM SIDC - RWC BELGIUM 2020 Oct 30 12:30UTC

The two active regions (ARs) visible on the disk NOAA AR 2778 and 2779 have
decayed in complexity and size. Four C-class flares were observed from AR
2779, the largest was a C4.3 peaking at 11:50 UT on 29 October (partially
reported yesterday). More C-class flares can be expected, and M-class
flares remain possible but less likely.

No Earth directed CME was observed in the past 24 hours.

The greater than 10 MeV proton flux was at background levels over the past
24 hours. It is expected to stay at background levels for the next 24
hours. The greater than 2 MeV electrons are above the 10^3 pfu threshold.
The electrons are expected to descend below the threshold in the next 24
hours.

The speed of the solar wind decreased from 465 to 435 km/s in the past 24
hours. Bz was never below -5 nT and B reached 6 nT. The solar wind speed is
expected to remain at low speeds over the next 24 hours.

The geomagnetic conditions reached active levels both locally and globally
(KDourbes = 4, Kp = 4). Mostly quiet to unsettled conditions can be
expected in the next 24 hours.
