Weekly Propagation Summary – 2016 Jul 04 16:10 UTC

Weekly Propagation Summary (2016 Jul 04 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2016 Jul 04 0322 UTC.

Highlights of Solar and Geomagnetic Activity 27 June – 03 July 2016

Solar activity was very low. The disk was spotless for the entire period with no measurable flare activity.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels from 27-30 Jun and dropped to normal to moderate levels for the remainder of the period.

Geomagnetic field activity was quiet to unsettled on 27-28 Jun due to diminishing negative polarity CH HSS effects. Mostly quiet conditions were observed on 29 Jun. Quiet to unsettled conditions were observed for the remainder of the week with an isolated active period on 02/2100-2400 UTC due to effects from a series of coronal holes.

Forecast of Solar and Geomagnetic Activity 04 July – 30 July 2016

Solar activity is expected to be very low throughout the forecast period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 04-07, 16-19, and 22-26 Jul following recurrent CH HSS events.

Geomagnetic field activity is expected to be at quiet to unsettled levels early on 04 Jul followed by quiet conditions through 07 Jul. Quiet to unsettled conditions are expected to return from 08-15 Jul with active periods likely on 11-12 Jul due to effects from a series of recurrent coronal holes. Quiet conditions are expected to return from 16-18 Jul. Another recurrent CH HSS is expected to cause quiet to unsettled conditions from 19-23 Jul with isolated active periods likely on 19 Jul. Mostly quiet levels are expected for the remainder of the period with unsettled periods possible on 28 and 30 Jul due to recurrent coronal holes.
