Detailed Information

Solar Activity

Solar activity was active over the past 24 hours.

A total of five solar flares were observed, comprising four C-class flares and one M-class flare, with no X-class flares detected. The most significant event was an M6.7 flare originating from NOAA 14549, which peaked at 15:48UT. No solar radio bursts were observed; specifically, no Type II, Type III, or Type IV radio bursts were detected. One coronal mass ejection was observed, propagating from the western limb with a speed of 428 km/s and an angular width of 124 degrees.

On the visible disk, three active regions were identified by SDO/HMI: NOAA 14545, NOAA 14548, and NOAA 14549. Additionally, two H-Alpha plages were detected by BBSO, corresponding to NOAA 14547 and NOAA 14550. Five active regions are due to return from the farside between 09 Oct and 11 Oct.

Based on today's conditions, solar activity for:

October 9th, 2026 04:00 UT - October 10th, 2026 03:59 UT is predicted to be active.
October 10th, 2026 04:00 UT - October 11th, 2026 03:59 UT is predicted to be eruptive.
October 11th, 2026 04:00 UT - October 12th, 2026 03:59 UT 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 396 km/s to 344 km/s, north-south component of interplanetary magnetic field fluctuate between -4.5 nT and 2.6 nT. Corona hole at was not geoeffective. CME on 08 October 2026 16:12 UT was Halo II with speed of 428 km/s and angular width of 124°. The CME was geoeffective and is likely to have not impact until next 3 days.

Quiet level geomagnetic activity is expected for 9 October 2026 04:00UT - 10 October 2026 03:59UT.
Quiet level geomagnetic activity is expected for 10 October 2026 04:00UT - 11 October 2026 03:59UT.

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  30 minutes. There was increment of fmin more than 30% of its median values for  30 minutes. The Spread-F occured  for  390 minutes. The Sporadic E layer occured in the night and daytime  for  570 minutes with foEs value exceeded the foF2  for  105 minutes. The S4 index values (condition of ionospheric scintillation) was on Moderate (S4 < 0.8) level last 24 hours over Agam. The TEC values was on Quiet (VTEC < 125) level last 24 hours over Agam. 

The ionosphere activity on October 9th, 04:00 UT - October 10th, 03:59 UT is predicted to be Quiet.
The ionosphere activity on October 10th, 04:00 UT - October 11th, 03:59 UT is predicted to be Quiet.

Navigation

For the last 24 hours, the error of the single frequency GPS positioning was on Slight level. 

The probability of error positioning on October 9th, 04:00 UT - October 10th, 03:59 UT is predicted to be Slight, based on scintillation and TEC variations.
