Here is this week’s space weather and geophysical report, issued 2019 Oct 28 0109 UTC.

Highlights of Solar and Geomagnetic Activity 21 – 27 October 2019

Solar activity was very low. The solar disk was spotless throughout the period. A faint, slow-moving, possibly Earth-directed CME was observed in satellite imagery at 25/0654 UTC, with a potential arrival late on 29 Oct or early on 30 Oct.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 25-27 Oct with a peak flux of 36,223 pfu observed at 27/1900 UTC. Electron flux was at normal levels throughout the remainder of the reporting period.

Geomagnetic field activity reached G2 (Moderate) storm levels on 25 Oct, G1 (Minor) storm levels on 26 Oct, and active levels on 24 Oct in response to a recurrent, positive-polarity CH HSS. Quiet to unsettled conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 28 October – 23 November 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 reach high levels on 28-31 Oct, and 21-23 Nov, with moderate levels on 01-15, and 20 Nov, in response to coronal hole high speed stream (CH HSS) influence.

Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 21-22 Nov, with active levels on 28-30 Oct, and 20, 23 Nov, due to recurrent CH HSS activity. Quiet to unsettled conditions are anticipated throughout the remainder of the outlook period.

Here is this week’s space weather and geophysical report, issued 2019 Oct 14 0407 UTC.

Highlights of Solar and Geomagnetic Activity 07 – 13 October 2019

Solar activity was very low. The solar disk was spotless. No Earth-directed coronal mass ejections (CMEs) were observed.

Here is this week’s space weather and geophysical report, issued 2019 Sep 23 0156 UTC.

Highlights of Solar and Geomagnetic Activity 16 – 22 September 2019

Solar activity was at very low levels. No sunspots were observed on the visible disk. An approximately 20 degree filament erupted near S35W02 around 19/2200 UTC which produced a narrow, slow-moving CME signature near the Sun-Earth line. Modeling of the event suggested most of the ejecta was oriented south and eastward of Earth's orbit; however, Earth may still observe weak influence from the periphery of the CME.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels from 16-21 Sep and dropped to just normal levels through 22 Sep.

Geomagnetic field activity was quiet to active conditions. Elevated wind speeds from a waning positive polarity CH HSS produced isolated active conditions on 16 Sep. Variable phi angle on 17 Sep suggested influence from a SSBC, cause a period of isolated active conditions. Quiet to unsettled levels on 18 Sep decreased to just quiet levels on 19-20 Sep. A brief period of southward Bz produced a single period of unsettled on 21 Sep. The remainder of the summary period was quiet.

Forecast of Solar and Geomagnetic Activity 23 September – 19 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 range from normal to high levels. High levels are expected on 28 Sep – 12 Oct and 14 Oct; moderate levels are expected on 24-27 Sep, 13 Oct, and 15-18 Oct. The remainder of the outlook period is expected to be at normal levels. All enhancements in electron flux are in anticipation of multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to be at quiet to G2 (Moderate) geomagnetic storm levels. G2 levels are expected on 28 Sep followed by G1 (Minor) geomagnetic levels on 29 Sep. Active conditions are expected on 23-25 Sep, 30 Sep and 06 Oct. Unsettled conditions are expected on 26-27 Sep, 01-03 Oct, 10 Oct and 12-15 Oct. The remainder of the outlook period is expected to be at quiet levels. All enhancements in geomagnetic activity are in anticipation of multiple, recurrent CH HSSs.

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.
