Solar activity was mostly at very low levels during June. The solar disk was spotless from 06-10 Jun. No Earth-directed coronal mass ejections (CMEs) were observed during June.
The Solar flux reached high levels on 11-13 Jun and decreased to moderate levels on 14- 22 June, and high levels were reached on 24 June in response to an enhanced solar wind environment.
Geomagnetic field activity generally ranged from quiet to active with a G1 minor storm period observed on 18-19 Jun followed by quiet to unsettled conditions for the remainder of June
Propagation forecast until 21 July
Solar activity is expected to be at very low levels from 29 Jun - 10 Jul. Very low levels are also expected from 11 July with a chance of C-class flare activity, through the remainder of the outlook period.
The solar flux is expected to be at high levels on 28 Jun - 10 July, due to Coronal Hole High Speed Streams (CH HSS), for the remainder of the outlook period.
Geomagnetic field activity is expected to be at unsettled levels on 15 Jul and 20-21 Jul following minor storms 27-28 Jun, all due to recurrent CH HSS activity. https://bit.ly/2KsGj3l
