Detailed Information

Solar Activity

Solar activity for November 6th, 2026 04:00 UT - November 7th, 2026 03:59 UT was eruptive,
Solar activity for November 7th, 2026 04:00 UT - November 8th, 2026 03:59 UT was active,
Solar activity for November 8th, 2026 04:00 UT - November 9th, 2026 03:59 UT was active.

Solar activity was active over the past 24 hours. A total of 25 solar flares were observed, comprising 22 C-class flares and 3 M-class flares. No X-class flares were observed. The strongest event was an M1.7 flare originating from NOAA 14566, peaking at 7:46UT. There were no solar radio bursts of Type II, Type III, or Type IV reported. One coronal mass ejection was detected, propagating westward with a speed of 255 kilometers per second and an angular width of 16 degrees. No eastward coronal mass ejection activity was observed. On the visible disk, four active regions were identified by SDO/HMI: NOAA 14565, NOAA 14566, NOAA 14568, and NOAA 14571. Additionally, two H-Alpha plages were observed by BBSO, identified as NOAA 14564 and NOAA 14570. One farside region is anticipated to return, with its emergence expected between 09 November and 11 November.

Basen on today's activity, solar activity is predicted to be at a active level for the next 24 hours with the maximum M flare.

Geomagnetic Activity

The geomagnetic activity was at quiet level on 6 November 2026 04:00UT - 7 November 2026 03:59UT.

The geomagnetic activity was at active level on 7 November 2026 04:00UT - 8 November 2026 03:59UT.

The geomagnetic activity was on quiet level on 8 November 2026 04:00UT - 9 November 2026 03:59UT.

The solar wind speed increase from 662 km/s to 717 km/s, north-south component of interplanetary magnetic field fluctuated between -3.8 nT and 4.2 nT. There was geoeffective corona hole at western equator.

Active level geomagnetic activity is expected for the next 24 hours.

Ionospheric Activity

Ionosphere was in Quiet level on November 6th, 04:00 UT - November 7th, 03:59 UT.
Ionosphere was in disturbed on Minor level on November 7th, 04:00 UT - November 8th, 03:59 UT.
Ionosphere was in Quiet level on November 8th, 04:00 UT - November 9th, 03:59 UT.

There was depression of foF2 lower than 30% of its median values for  15 minutes and 120 minutes on  November 6th-7th and November 7th-8th.There was increment of fmin more than 30% of its median values for  60 minutes, 75 minutes, and 15 minutes for 3 consecutive days. The Spread-F occured  for  90 minutes, 45 minutes, and 15 minutes for 3 consecutive days. The Sporadic E layer occured in the night and daytime  for  585 minutes, 615 minutes, and 480 minutes on  November 6th-7th, November 7th-8th, and November 8th-9th with foEs value exceeded the foF2  for  150 minutes, 60 minutes, and 105 minutes for 3 consecutive days. The S4 index values (condition of ionospheric scintillation) was on Moderate (S4 < 0.8) level on November 6th-7th,  and on Quiet (S4 < 0.5) level on November 7th-9th  over Agam. The TEC values was on Quiet (VTEC < 125) for 3 consecutive days  over Agam. 

The ionosphere activity for the next 24 hours is predicted to be Minor.

Navigation

On November 6th, 04:00 UT - November 7th, 03:59 UT, the error of the single frequency GPS positioning was on Slight level. 
On November 7th, 04:00 UT - November 8th, 03:59 UT, the error of the single frequency GPS positioning was on Normal level. 
On November 8th, 04:00 UT - November 9th, 03:59 UT, the error of the single frequency GPS positioning was on Normal level. 

The probability of error positioning for the next 24 hours is predicted to be Normal, based on scintillation and TEC variations.

HF Radio Communication

On November 6th, 04:00 UT - November 7th, 03:59 UT, The MUF(Maximum Usable Frequency) depression was in Quiet condition  and the SWF (Short Wave Fadeout) was in Moderate.
On November 7th, 04:00 UT - November 8th, 03:59 UT, The MUF(Maximum Usable Frequency) depression was in Moderate condition  and the SWF (Short Wave Fadeout) was in Moderate.
On November 8th, 04:00 UT - November 9th, 03:59 UT, The MUF(Maximum Usable Frequency) depression was in Quiet condition  and the SWF (Short Wave Fadeout) was in Quiet.

The MUF depression for the next 24 hours is predicted to be Minor, based on prediction of geomagnetic activity.

The SWF for the next 24 hours is predicted to be Minor, based on prediction of Solar activity.

Satellites

The electron flux was at high level on 6 November 2026 04:00UT - 7 November 2026 03:59UT.

The electron flux was at low level on 7 November 2026 04:00UT - 8 November 2026 03:59UT.
