Detailed Information

Solar Activity

Solar activity was quiet for the last 24 hours. Neither flare, solar radio burst nor CME occurred in the last 24 hours. Based on the latest observation by SDO Intensitygram, shows spotted Sun. Stereo EUVI/AIA 195 observation shows no new active region to appear from the east limb of the Solar disk in the next 24 hours.

Based on today's condition, solar activity for the next 24 hours is predicted to be quiet.

Geomagnetic Activity

The geomagnetic activity was on quiet level for the last 24 hours.
The solar wind speed tend to fluctuate from 320 km/s to 350 km/s. North-south component of interplanetary magnetic field fluctuated from -4 to 2 nT. There was no geoeffective coronal hole at both eastern equator and south pole.

Quiet level geomagnetic is expected for the next 24 hours.

Ionospheric Activity

Ionosphere was in minor level conditions for the last 24 hours.

There was depression of foF2 lower than 30% of its median value for 45 minutes. There was no increment of fmin more than 30% of its median values . The Spread-F occurred for 105 minutes . The Sporadic-E occurred in the night and daytime with foEs value exceeded the foF2 for several times during 1005 minutes. The W-index mean value was -1. The S4 index values (condition of ionospheric scintillation ) was less than 0.5 over Bandung.

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

Navigation

Based on W-index, the error of the single frequency GPS positioning for last 24 hours was in Normal level.

 

Based on the prediction of W-index = -1, the probability of error positioning for the next 24 hours is predicted on Normal level.

HF Radio Communication

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

 

The MUF depression for the next 24 hours is predicted on Moderate level, due to based on LAPAN Time Series method.

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

Satellites

The maximum value of electron flux was 10 particles/cm2.sec.sr low level for the last 24 hours.

Low level electron flux is expected on the next 24 hours.

The flux of high-energy proton was in quiet for last 24hours. 

Based on today's condition, the flux of high-energy proton for the next 24 hours is predicted to be quiet.
