Detailed Information

Solar Activity

Solar activity over the past 24 hours was eruptive. A single C-class flare, specifically a C1.1 event, was observed, peaking at 22:39UT from an unknown location. No M-class or X-class flares were observed. No solar radio bursts were reported during the past 24 hours. Associated with this activity, one coronal mass ejection was detected, originating from the east limb with a speed of 194 km/s and an angular width of 66 degrees.

On the visible disk, three active regions were observed by SDO/HMI: NOAA 14564, NOAA 14565, and NOAA 14566. Additionally, one H-Alpha plage was identified by BBSO as NOAA 14562. One farside region is expected to return to the visible disk between November 04 and November 06. Looking ahead, solar activity is predicted to remain eruptive for the next 24 hours, with the Random Forest model predicting a maximum C-class flare.

Geomagnetic Activity

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

The solar wind speed stable around 414 km/s, north-south component of interplanetary magnetic field fluctuate between -4.5 nT and 4.5 nT Corona hole at was not geoeffective.

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

 

Ionospheric Activity

Ionosphere was in Quiet conditions for the last 24 hours.There was no depression of foF2 lower than 30% of its median value for last 24 hours. There was increment of fmin more than 30% of its median value for 45 minutes for the last 24 hours. There was The Spread-F occurred For 195 minutes for the last 24 hours. There was The Sporadic-E occurred in the night and daytime for 465 minutes with foEs value exceeded the foF2 for last 24 hours. S4 index values (condition of ionospheric scintillation ) was less than 0.5 over Kototabang Agam. The ionosphere activity for next 24 hours is predicted to be Quiet.

Navigation

Based on TEC variation 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 on the next 24 hours is predicted on 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 for next 24 hours is predicted on Quiet level, due to previous of geomagnetic activity

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

 

Satellites

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

High level of elektron flux is expected for the next 24 hours.

The 10 MeV proton flux remained quiet over the past 24 hours. These quiet conditions are predicted to continue for the next 24 hours.
