Detailed Information

Solar Activity

Solar activity was observed to be Active over the past 24 hours. A total of 11 solar flares were detected, comprising 10 C-class flares and 1 M-class flare. No X-class flares were observed. The strongest event was an M1.7 class flare originating from NOAA 14566, peaking at 21:21UT. Associated with this activity, no Type II, Type III, or Type IV solar radio bursts were reported. One coronal mass ejection was observed, propagating to the west with a speed of 935 kilometers per second and an angular width of 44 degrees.

On the visible disk, eight active regions were identified by SDO/HMI: NOAA 14565, NOAA 14566, NOAA 14568, NOAA 14569, NOAA 14572, NOAA 14573, NOAA 14574, and NOAA 14575. Additionally, one H-Alpha plage, NOAA 14570, was observed by BBSO. One region is currently on the farside and is expected to return to the visible disk between November 12 and November 14. Looking ahead, solar activity is predicted to remain Active for the next 24 hours, with the Random Forest model forecasting a maximum flare class of M.

Geomagnetic Activity

The geomagnetic activity was on quiet level for the last 24 hours.

The solar wind speed stable around 615 km/s, north-south component of interplanetary magnetic field fluctuate between -3.6 nT and 3.9 nT Corona hole at was not geoeffective. CME on 11 November 2026 23:24 UT was mainly errupted toward north-west with speed of 935 km/s and angular width of 44°. The CME was geoeffective and is likely to have not impact on next 24 hours.

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

Ionospheric Activity

Ionosphere was in Quiet level for the last 24 hours.

There was no depression of foF2 lower than 30% of its median values.There was increment of fmin more than 30% of its median values for 45 minutes. The Spread-F occured for 60 minutes. The Sporadic E layer occured in the night and daytime for 765 minutes with foEs value exceeded the foF2 for 120 minutes. The S4 index values (condition of ionospheric scintillation) was on Quiet (S4 < 0.5) level last 24 hours over Agam. The TEC values was on Quiet (VTEC < 125) level last 24 hours over Agam.

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

Navigation

For the last 24 hours, 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

The MUF(Maximum Usable Frequency) depression was in Quiet condition and the SWF (Short Wave Fadeout) was in Moderate for the last 24 hours.

The MUF depression for the next 24 hours is predicted to be Quiet, 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 on high level for the last 24 hours.

High level of electron flux is expected for the next 24 hours.

The 10 MeV proton flux remained Quiet over the past 24 hours. These quiet conditions are predicted to continue for the next 24 hours.
