Detailed Information

Solar Activity

Solar activity over the past 24 hours was quiet.

No C-class, M-class, or X-class flares were observed, and consequently, no solar radio bursts were reported. Furthermore, no coronal mass ejections were detected during this period. On the visible disk, SDO/HMI observations revealed three active regions: NOAA 14564, NOAA 14565, and NOAA 14566. Additionally, one H-Alpha plage, NOAA 14562, was observed by BBSO. Two farside regions are expected to return to the visible disk between November 03 and November 05.

Solar activity for the next 24 hours is predicted to be eruptive, with the Random Forest model forecasting a maximum flare class of C.

Geomagnetic Activity

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

The solar wind speed decreased from 815 km/s to 423 km/s; the north-south component of the interplanetary magnetic field fluctuated between -5.5 nT and 3.6 nT. The coronal hole was not geoeffective.

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 depression of foF2 lower than 30% of its median values for 15 minutes.There was increment of fmin more than 30% of its median values for 135 minutes. The Spread-F occured for 105 minutes. The Sporadic E layer occured in the night and daytime for 705 minutes with foEs value exceeded the foF2 for 150 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 Strong 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 a high level for the last 24 hours.
A 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 conditions are expected to continue, with the proton flux predicted to remain quiet for the next 24 hours.
