Detailed Information

Solar Activity

Solar activity over the past 24 hours was active. 

A total of 8 solar flares were observed, consisting of six C-class flares and two M-class flare. The strongest event was an M1.8 flare from NOAA 14549, which peaked at 08:05 UT. There were 5 solar radio bursts reported; specifically, 5 Type-III and 1 Type II radio burst. Five coronal mass ejections were detected. One CME propagated to the west at a speed of 393 kilometers per second with an angular width of 134 degrees, while another CME was observed propagating to the east at 251 kilometers per second with an angular width of 16 degrees. On the visible disk, SDO/HMI imagery revealed four active regions: NOAA 14545, NOAA 14547, NOAA 14548, and NOAA 14549. No  H-alpha plage was observed by BBSO.No new region is due to return from the farside within the next 24 hours.

Solar activity for the next 24 hours is predicted to be eruptive.

Geomagnetic Activity

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

The solar wind speed decrease from 616 km/s to 504 km/s, north-south component of interplanetary magnetic field stable around -0.7 nT Corona hole at was not geoeffective. CME on 06 October 2026 14:12 UT was mainly errupted toward north-west with speed of 555 km/s and angular width of 10°. The CME was geoeffective and is likely to have not impact on next 24 hours.

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

Ionospheric Activity

Ionosphere was in disturbed on Minor level for the last 24 hours.

There was depression of foF2 lower than 30% of its median values for 45 minutes.There was increment of fmin more than 30% of its median values for 75 minutes. The Spread-F occured for 30 minutes. The Sporadic E layer occured in the night and daytime for 285 minutes with foEs value exceeded the foF2 for 15 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 Moderate 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 Quiet, based on prediction of Solar activity.

Satellites

The electron flux was on very high level for the last 24 hours.

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

The 10 MeV proton flux was quiet over the past 24 hours. 
Based on these conditions, the proton flux is predicted to remain quiet for the next 24 hours.
