Highlights of Solar and Geomagnetic Activity
27 July - 02 August 2020

Solar activity was very low throughout the period. Three spotted
regions populated the disk at various times during the summary
period. Region 2767 (S21, L=200, class/area Hsx/120 on 26 Jul)
maintained an H-type configuration through the period and was quiet
and stable. Region 2768 (N26, L=111, class/area Hsx/020 on 30 Jul)
formed on the disk on 28 Jul and decayed to plage by 02 Aug. It was
quiet and stable. Region 2769 (N26, L=059, class/area Axx/010 on 02
Aug) quietly rotated onto the disk. 

An eruptive prominence was observed off the SE limb about midday on
31 Jul. A slow-moving CME was subsequently observed, but was
determined to not have an Earth-directed component. No other CMEs or
activity of note was observed during the summary period. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels through the period. 

Geomagnetic field activity was at quiet levels through midday on 02
Aug when unsettled activity was observed due to positive polarity CH
HSS influence. Solar wind observations indicated nominal conditions
through about 02/0600 UTC when a CIR, in advance of a positive
polalarity CH HSS, became evident in the data. Wind speeds increased
from about 310 km/s to near 530 km/s, total field increased to 12 nT
and the Bz component reached -10 nT. The geomagnetic field reacted
with mostly unsettled conditions. 

Forecast of Solar and Geomagnetic Activity
03 August - 29 August 2020

Solar activity is expected to be at very low levels throughout the
outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels throughout the outlook
period. 

Geomagnetic field activity is expected to be at unsettled to active
levels through 03 Aug with a chance for G1 (Minor) geomagnetic storm
levels due to recurrent CH HSS effects. Quiet to unsettled levels
are expected on 04 Aug as HSS effects persist. Unsettled levels are
expected once again on 29 Aug. Quiet levels are expected to prevail
for the remainder of the period, 05-28 Aug.
