Here is this week’s space weather and geophysical report, issued 2019 Sep 16 0139 UTC.

Highlights of Solar and Geomagnetic Activity 09 – 15 September 2019

Solar activity was at very low levels. No spots were observed on the visible disk. 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 moderate to high levels throughout the summary period due to influence from multiple CH HSSs. A maximum flux of 8,450 pfu was observed at 09/1745 UTC.

Geomagnetic field activity ranged from quiet to active levels. An isolated period of active was observed on 09 Sep in response to a positive polarity CH HSS increasing solar wind speeds to ~525 km/s. Isolated unsettled conditions, associated with further enhancements from multiple positive polarity CH HSSs, were observed on 12-15 Sep. Quiet conditions were observed over the remainder of the summary period.

Forecast of Solar and Geomagnetic Activity 16 September – 12 October 2019

Solar activity is expected to be at very low levels over the outlook 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 16-19 Sep and 27 Sep – 12 Oct. Moderate levels are expected from 20-26 Sep. All enhancements in electron flux are due to elevated wind speeds from multiple, recurrent, CH HSSs.

Geomagnetic field activity is expected to range from quiet to G2 (Moderate) storm levels. G2 conditions are likely on 27-28 Sep; G1 (Minor) conditions are likely on 29 Sep; active conditions are likely on 30 Sep and 02 Oct; unsettled conditions are likely on 16-18 Sep, 23 Sep, 26 Sep, 01 Oct, 03 Oct, 06 Oct, 10 Oct and 12 Oct. All enhancements in geomagnetic active are in response to the anticipated influence of multiple, recurrent CH HSSs. The remainder of the outlook period is expected to be mostly quiet under nominal solar wind conditions.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels from 09-13 Sep, and again from 27 Sep – 06 Oct due to HSS effects. Normal to moderate levels are expected on 14-26 Sep.

Geomagnetic field activity is expected to be at mostly quiet levels on 09-26 Sep. Isolated unsettled periods are possible on 23, 26 and 30 Sep, and 01-03 Oct. G1 (minor) to G2 (moderate) geomagnetic storm levels are likely on 27-29 Sep due to positive polarity CH HSS effects.

Here is this week’s space weather and geophysical report, issued 2019 Aug 05 0339 UTC.

Highlights of Solar and Geomagnetic Activity 29 July – 04 August 2019

Solar activity was very low under a spotless solar disk. Other activity included a filament eruption observed in SDO/AIA 304 imagery beginning at 04/1640 UTC in the NW quadrant. Analysis is on-going for any potential coronal mass ejections (CMEs) as coronagraph imagery becomes available.

No proton events were observed at geosynchronous orbit.

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

Geomagnetic field activity ranged from quiet to unsettled levels. Solar wind parameters indicated the arrival of a co-rotating interaction region (CIR) preceding a negative polarity coronal hole high speed stream (CH HSS) beginning midday on 30 Jul. Total field increased to 11 nT by 30/2024 UTC while solar wind speed increased to a maximum of 596 km/s at 01/0503 UTC. The geomagnetic field responded with quiet to unsettled periods on 30 Jul-01 Aug.

Forecast of Solar and Geomagnetic Activity 05 August – 31 August 2019

Solar activity is expected to continue at very low levels for the forecast period (05-31 Aug).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach moderate levels on 05 Aug and 18 Aug. High levels are expected on 06-17 Aug due to CH HSS influence.

Geomagnetic field activity is expected to be reach unsettled to active levels on 05-08, 10-11, 17-18, 26-28, and 31 Aug with G1 (Minor) geomagnetic storm levels likely on 05-06 Aug due to recurrent CH HSS effects.
