Highlights of Solar and Geomagnetic Activity 17 - 23 June 2019

Solar activity was at very low levels. No sunspots were observed on the visible disk. No Earth-directed CMEs were observed in available imagery.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 17 Jun with a peak flux of 109 pfu observed at 17/2025 UTC. Normal levels were observed on 18-23 Jun.

Geomagnetic field activity was at quiet levels with an isolated unsettled period observed for 0600-0900 UTC period on 20 June. Solar wind parameters were at mostly nominal levels through the period. A peak wind speed of near 425 km/s was observed early on 22 Jun. Bt and Bz parameters were at mostly nominal levels.

Forecast of Solar and Geomagnetic Activity 24 June - 20 July 2019

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 moderate to high levels on 25 Jun - 03 Jul in response to the elevated wind speeds associated with recurrent CH HSS  activity. Normal levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach unsettled to isolated active levels on 24-26 Jun, 06 Jul and 10-11 Jul due to negative polarity CH HSS influence. Quiet conditions are expected for the remainder of the outlook period.
