Weekly Propagation Summary – 2018 Aug 06 16:10 UTC

Weekly Propagation Summary (2018 Aug 06 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Aug 06 0236 UTC.

Highlights of Solar and Geomagnetic Activity 30 July – 05 August 2018

Solar activity was very low throughout the period. Region 2717 (S08, L=027, class/area=Axx/10 on 02 Aug) was briefly the sole active region with sunspots, but was largely unproductive. No Earth-directed CMEs were observed this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 30 Jul, moderate levels on 31 Jul, and 01, 03-04 Aug. Normal levels were observed throughout the rest of the period.

Geomagnetic field activity was quiet to unsettled on 31 Jul, and 01-03 Aug, with quiet conditions observed throughout the remainder of the period, under a nominal solar wind environment.

Forecast of Solar and Geomagnetic Activity 06 August – 01 September 2018

Solar activity is expected to be very low 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 21-26 Aug. Moderate levels are expected on 06-11, 18-20, 27-31 Aug and 01 Sep. Normal levels are expected throughout the remainder of the outlook period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 20 Aug due to the influence of a negative polarity, coronal hole high-speed stream. Active conditions are expected on 07-08, 17, and 20-21 Aug due to multiple, recurrent coronal hole high-speed streams. Quiet to unsettled conditions are expected throughout the remainder of the outlook period.

Weekly Propagation Summary – 2018 Jul 16 16:10 UTC

Weekly Propagation Summary (2018 Jul 16 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Jul 16 0150 UTC.

Highlights of Solar and Geomagnetic Activity 09 – 15 July 2018

Solar activity was very low throughout the reporting period. The visible disk produced several plage regions but no visible spots were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels. Moderate levels were reached on 09-11 Jul and 13-17 Jul.

Geomagnetic field activity was mostly quiet with several periods of unsettled observed on 11-12 Jul. A slow-moving transient signature was observed in the solar wind midday on 10 Jul from a CME first observed in STEREO AHEAD COR 2 imagery early on 05 Jul. A decrease in solar wind speeds was observed, after the onset, which lowered winds from near 385 km/s to 309 km/s at its slowest point on 11 Jul. Total magnetic field strength peaked at arrival with 13 nT. Bz was mostly oriented either near neutral or northward which produced a quiet to unsettled geomagnetic response throughout the duration of the transient.

Forecast of Solar and Geomagnetic Activity 16 July – 11 August 2018

Solar activity is expected to remain very low 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 range from moderate to high levels. Moderate to high level are expected over 21-31 Jul and normal to moderate levels are expected through the remainder of the outlook period. All enhancements in the greater than 2 MeV electron flux are due to the anticipated influence of multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G1 (Minor) geomagnetic storm levels. Unsettled levels are expected on 16 Jul, 21 Jul and 24 Jul; active levels are expected on 20 Jul and 22 Jul; G1 (Minor) geomagnetic storm levels are expected on 23 Jul. All increases in geomagnetic activity are in anticipation of multiple, recurrent CH HSSs.

Weekly Propagation Summary – 2018 Jul 09 16:10 UTC

Weekly Propagation Summary (2018 Jul 09 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Jul 09 0254 UTC.

Highlights of Solar and Geomagnetic Activity 02 – 08 July 2018

Solar activity was very low levels through most of the reporting period. However, on 06 Jul, A C1 flare was observed at 06/2007 UTC from an area of enhanced flux, as observed in STEREO AHEAD 195 imagery, from around the E. limb. The area later rotated onto the visible disk as spotless plage. Several DSFs were observed on 05 Jul from the NE quadrant, though none were thought to have produced Earth-directed CMEs.

A coronal dimming in the SW quadrant was observed in SDO/AIA 193, around 04/2325 UTC, which was followed by an observation of a slow-moving CME first observed in STEREO AHEAD COR2 imagery beginning around 04/0324 UTC. No clear signature was observed in SOHO LASCO C2 or C3 imagery. Modeling of the event suggested the possibility of an Earth-directed component becoming geoeffective sometime after 09 Jul.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate to high levels on 02-04 Jul and decreased to normal to moderate levels on 05-08 Jul.

Geomagnetic field activity ranged from quiet to G1 (Minor) geomagnetic storm levels. Quiet conditions were observed from 02-04 Jul. A SSBC on 05 Jul increased total magnetic field strength to 12 nT and solar wind speeds to around 450 km/s. The field response increased from quiet to an isolated period of G1 (Minor) storm levels. Wind speeds continued between 400-525 km/s for the remainder of the reporting period; however, only quiet conditions were observed after 06/0300 UTC.

Forecast of Solar and Geomagnetic Activity 09 July – 04 August 2018

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 range from normal to high levels. Normal to moderate levels are expected from 09-20 Jul and 01-04 Aug; moderate to high levels are expected from 21-31 Jul. All enhancements in electron flux are anticipated in response to recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to G1 (Minor) geomagnetic storm levels. A slow-moving CME, first observed early on 05 Jul, is forecast to cause active levels on 09 Jul and unsettled levels on 10 Jul. Influences from multiple, recurrent, CH HSSs are expected to increase geomagnetic activity to unsettled levels on 16 Jul, 21 Jul and 24 Jul; active levels are likely on 15 Jul, 20 Jul, 22 Jul; G1 (Minor) storm levels are likely on 23 Jul. The remainder of the forecast period is expected to produce quiet levels under nominal solar wind conditions.

Weekly Propagation Summary – 2018 Jul 02 16:10 UTC

Weekly Propagation Summary (2018 Jul 02 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Jul 02 0504 UTC.

Highlights of Solar and Geomagnetic Activity 25 June – 01 July 2018

Solar activity was at very low levels. Region 2715 (N08, L=231, class/area Dao/070 on 23 Jun) was the only spotted region on the disk and was quiet throughout the summary period. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period. A maximum flux of 5,570 pfu was observed at 28/1935 UTC.

Geomagnetic field activity was at quiet to isolated G1 (Minor) storm periods from late on 25 Jun through 26 Jun in response to an SSBC from a positive to a negative sector observed midday on 25 Jun. A CIR signature was evident early on 26 Jun in advance of an equatorial, negative polarity CH HSS. Total field (Bt) peaked at 14 nT, the Bz component reached a maximum negative extent of -9 nT and wind speeds increased from about 400 km/s to about 670 km/s; all during 26 Jun. For the remainder of the summary period, field conditions were at quiet levels with an isolated unsettled interval late on 27 Jun. By the end of the summary period, Bt and Bz were at nominal levels while wind speeds decreased to near 350 km/s.

Forecast of Solar and Geomagnetic Activity 02 July – 28 July 2018

Solar activity is expected to be at very low levels through 10 Jul. With the return of old Region 2715 (N08, L=231) from 11-24 Jul, activity levels are expected to remain at very low levels, with a slight chance for C-class activity. A return to very low levels is expected from 25-28 Jul.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 02-10 Jul and again on 21-28 Jul due to CH HSS influence. Normal to moderate levels are expected from 11-20 Jul.

Geomagnetic field activity is expected to be at unsettled to active levels on 15 Jul and 20-24 Jul with isolated G1 (Minor) geomagnetic storms likely on 23 Jul, all due to recurrent CH HSS activity. Mostly quiet levels are expected for the remainder of the outlook period.

Weekly Propagation Summary – 2018 Jun 25 16:10 UTC

Weekly Propagation Summary (2018 Jun 25 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Jun 25 0343 UTC.

Highlights of Solar and Geomagnetic Activity 18 – 24 June 2018

Solar activity was at predominately very low levels with an isolated C2/Sf flare observed at 21/0115 UTC from Region 2715 (N08, L=231, class/area Dac/120 on 23 Jun). This region, as well as Region 2713 (N05, L=289, class/area Dao/070 on 23 Jun), also produced numerous B-class flares during the period. No Earth-directed CMEs were observed during the period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 18 and 23 Jun and moderate levels on 19-22 Jun. High levels were reached on 24 Jun in response to an enhanced solar wind environment.

Geomagnetic field activity generally ranged from quiet to active levels with an isolated G1 (Minor) storm period observed early on 18 Jun. The period began under the influence of a waning, positive polarity CH HSS. Wind speeds peaked at 525-540 km/s early to midday on 18 Jun with the Bz component variable between +16 nT to -9 nT. On 18 Jun through midday on 19 Jun, field conditions ranged from quiet to isolated G1 geomagnetic storm conditions. From midday 19 Jun through early on 23 Jun, solar wind parameters were at mostly nominal levels with a quiet geomagnetic field.

Early on 23 Jun, solar wind parameters indicated a weak CIR signature in advance of another positve polarity CH HSS. Wind speeds gradually increased from about 325 km/s to a peak of near 515 km/s by the end of 23 Jun. Total field strength peaked at 15 nT midday on 23 Jun while the Bz component varied between +12 nT to -15 nT through midday on the 23rd before relaxing to a variable +/-9 nT through the summary end. Field conditions responded with quiet to active conditions on 23 Jun and quiet to isolated unsettled conditions on 24 Jun.

Forecast of Solar and Geomagnetic Activity 25 June – 21 July 2018

Solar activity is expected to be at predominately very low levels with a chance for C-class flare activity on 25-28 Jun until Region 2715 rotates off the visible disk. Very low levels are expected from 29 Jun – 10 Jul. With the return of old Region 2715 on 11 Jul, very low levels, with a chance for C-class flare activity, is expected through the remainder of 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 be at high levels on 25-26 Jun and 28 Jun – 10 Jul due to CH HSS influence. Normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to be at unsettled to active levels on 25-30 Jun, 15 Jul and 20-21 Jul with G1 (Minor) storm levels expected on 27-28 Jun, all due to recurrent CH HSS activity.
