Detailed Information

Solar Activity

Solar activity over the past 24 hours was eruptive.

A total of fifteen C-class solar flares were observed, with no M-class or X-class flares. The most significant event was a C5.7 flare, peaking at 4:10 UT, originating from NOAA 14566. No solar radio bursts of Type II, Type III, or Type IV were reported. Meanwhile, two coronal mass ejections were observed; one originating from the western hemisphere exhibited an estimated speed of 675 km/s and an angular width of 8 degrees, while another from the eastern hemisphere showed an estimated speed of 511 km/s and an angular width of 12 degrees. On the visible disk, SDO/HMI imagery revealed five active regions, identified as NOAA 14565, NOAA 14566, NOAA 14568, NOAA 14571, and NOAA 14572. Concurrently, BBSO H-alpha observations showed three plages, designated as NOAA 14564, NOAA 14569, and NOAA 14570. A farside active region is expected to return to the visible disk between November 10 and November 12.

The solar activity for the next 24 hours is predicted a major flare, with the Random Forest model forecasting a maximum flare class of X.

Geomagnetic Activity

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

The solar wind speed decrease from 814 km/s to 690 km/s, north-south component of interplanetary magnetic field fluctuate between -4.8 nT and 6.1 nT. Corona hole at western equator elongated to south pole was not geoeffective. CME on 09 November 2026 16:48 UT was mainly errupted toward west with speed of 675 km/s and angular width of 8°. 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  30 minutes. The Spread-F occured  for  90 minutes. The Sporadic E layer occured in the night and daytime  for  510 minutes with foEs value exceeded the foF2  for  105 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 Minor 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 Strong, 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 at quiet levels over the past 24 hours.

Based on these conditions, the proton flux is predicted to remain quiet for the next 24 hours.
