Solar activities was in the quiet level. Neither flare, CME nor solar radio burst was occurred in the last 24 hours. Today's observation from SDO/HMI Intensitygram shows that the Sun is spotless. Only two H-alpha plages exist on the solar disk. Based on STEREO EUVI/AIA195 observation, no new active region is predicted to appear from the east limb in the next 24 hours .
Based on today's condition, the solar activity is predicted to remain quiet, valid for the next 24 hours.
In the last 24 hours, geomagnetic activity was on quiet level.
Today's geomagnetic activity was on quiet level. Solar wind speed decreased from 600 km/s to 480 km/s. IMF was varied between -6 to 5 nT. Today's geoeffective coronal hole was on southern elongated to equator. The latest substorm occured on March 20th 2018 around 2 UT with intensity less than 500 nT and is still in progress.
Quiet level is expected for the next 24 hours.
Ionosphere was in quiet condition.
There was no depression of foF2 lower than 30% of its median values. There was no increment of fmin more than 30% of its median values. There was no Spread-F event. The Sporadic-E occurred in day to nighttime with foEs value less than foF2 values. The W-index mean value was -1. S4 index value (condition of ionospheric scintillation) over Bandung was less than 0.25.
The ionosphere activity is predicted to be quiet for the next 24 hours.
The Error positioning was normal based on w-index value.
The probability of error positioning for next the 24 hours is normal during daytime and nighttime based on W-index value that going to be 1.
MUF depression was in quiet condition and Short Wave Fadeout (SWF) was in quiet condition.
The probability of MUF depression for next the 24 hours is quiet due to previous and prediction of geomagnetic activity.
The probability of SWF for next the 24 hours is quiet due to the prediction of solar flare activities.
Today's Electron flux was around 10,000 [/cm2/sec/sr] or in Very high level.
Very High electron flux is expected for the next 24 hours.
The flux of high-energy proton was in the quiet level due to low solar activity.
The flux of high-energy proton is predicted to remain in the quiet level, valid for the next 24 hours.
