Detailed Information

Solar Activity

Solar activity over the past 24 hours was Quiet.

No C-class, M-class, or X-class flares were observed. Associated with this, no Type II, Type III, or Type IV solar radio bursts were reported. Furthermore, no coronal mass ejections were detected. On the visible disk, two active regions were identified by SDO/HMI: NOAA 14527 and NOAA 14528. Additionally, four H-alpha plages were observed by BBSO: NOAA 14524, NOAA 14525, NOAA 14529, and NOAA 14531. No farside regions were observed to be returning to the visible disk.

Looking ahead, the solar activity is predicted to remain Quiet for the next 24 hours, with the Random Forest model forecasting no-flare activity.

Geomagnetic Activity

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

The solar wind speed fluctuate between 308 km/s and 412 km/s, north-south component of interplanetary magnetic field fluctuate between -9.1 nT and 12.5 nT. There was geoeffective coronal hole at western equator, while the others at north pole and north-west were not geoeffective.

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

Ionospheric Activity

The ionosphere was on quiet level for the last 24 hours.

There was depression of foF2 lower than 30% of its median value for 15 minutes. There was increment of fmin more than 30% of its median values for 60 minutes. There was a Spread-F layer for 30 minutes.  The Sporadic E layer occured in the night and daytime for 870 minutes with foEs value exceeded the foF2 for 45 minutes.. The S4 index values (condition of ionospheric scintillation) was on quiet level (S4<0.5) on the last 24 hours over Agam. TEC index was on quiet level (VTEC<125) with the maximum value of 63.97 TECU on the last 24 hours over Agam.

The ionosphere activity on on the next 24 hours is predicted to be quiet  level.

Navigation

Based on TEC and scintilation, the error of the single-frequency GPS positioning for the last 24 hours was in normal level.

Based on ionospheric scintilation and TEC variation, the probability of error positioning in the next 24 hours is predicted in normal level.

HF Radio Communication

MUF Depression was in quiet condition and Short Wave Fadeout (SWF) was in moderate for the last 24 hours

The MUF depression on the next 24 hours is predicted in quiet level based on Geomagnetic activity.

The SWF for the next 24 hours is predicted in quiet level due to the prediction of the solar flare.

Satellites

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

Low 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 persist, with the 10 MeV proton flux predicted to remain Quiet for the next 24 hours.
