Highlights of Solar and Geomagnetic Activity
14 - 20 June 2021
Solar activity was at very low levels. The two regions on the disk,
Region 2833 (N24, L=210, class/area Cso/120 on 19 Jun) and Region
2834 (N20, L=281, class/area Bxo/010 on 18 Jun) were both quiet and
stable. No Earth-directed CMEs were observed in available
coronagraph imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate levels on 14-16 Jun and high levels on 17-20 Jun. A maximum
flux of 4,860 pfu was observed at 17/1435 UTC.
Geomagnetic field activity was at quiet levels on 14 Jun through
midday on 15 Jun. Unsettled to Gi (Minor) storm levels were observed
midday on 15 Jun due to influences from the arrival of a recurrent,
negative polarity CH HSS. Unsettled to active levels continued
through 16 Jun into early on 17 Jun. Solar wind speeds reached near
625 km/s, with total field readings of 15 nT and Bz readings of -10
nT, all on 16 Jun.
Forecast of Solar and Geomagnetic Activity
21 June - 17 July 2021
Solar activity is expected to be very low through 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 high levels on 21-23 Jun and on 14-17 Jul due to
recurrent CH HSS influences.
Geomagnetic field activity is expected to be at unsettled to active
levels on 24 Jun, 04 Jul, 09-10 Jul and 12-13 Jul due to recurrent
CH HSS influences. Mostly quiet conditions are expected for the
remainder of the outlook period.
