Detailed Information

Solar Activity

Solar activity was eruptive over the past 24 hours.

There was 1 C-class flare observed, C1.2 at 06:29 UT from NOAA 4534. No solar radio bursts reported and no coronal mass ejections were detected. On the visible disk, six active regions were identified by SDO/HMI: NOAA 4533, 4534, 4535, 4536, 4537, and 4538. Additionally, one H-Alpha plage were observed: NOAA 4532.

Based on today's condition, 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 419 km/s to 338 km/s, north-south component of interplanetary magnetic field fluctuate between -3.8 nT and 3.3 nT. Corona hole at south pole elongated to equator was 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 no increment of fmin more than 30% of its median value for the last 24 hours. There was The Spread-F occurred For 435 minutes for the last 24 hours. There was The Sporadic-E occurred in the night and daytime for 585 minutes with foEs value exceeded the foF2 for last 24 hours.

S4 index values (condition of ionospheric scintillation ) was less than 0.8 over Kototabang Agam 

The ionosphere activity for next 24 hours is predicted to be Quiet.

 

Navigation

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

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

HF Radio Communication

MUF depression was in Quiet condition and Short Wave Fadeout (SWF) was in Quiet 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 low level for the last 24 hours.

Low 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 current conditions, the proton flux is expected to be quiet for the next 24 hours.
