Solar activity was quiet without flare, CME nor solar radio burst detected. Today's observation shows the spotless Sun. According to 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, solar activity is predicted to be quiet for the next 24 hours.
The geomagnetic activitiy was on quiet level in the last 24 hours.
Today's geomagnetic activity was on quiet level. The solar wind speed was decreased from 475 to 375 km/s, proton densitiy tend to decreased from 8 to 1 part/cm³ and Bz component was varying around -5 to +5 nT. There is no geoeffective coronal holes for today. In the last 24 hours there was no substorm occurence
Quiet level is expected for next 24 hours.
Ionosphere was in minor conditions for the last 24 hours.
There was depression of foF2 lower than 30% of its median value. There was increment of fmin more than 30% of its median values. There was spread-F event for 30 minutes. The Sporadic-E occurred in day and night time. The W-index mean value was 3. The S4 index values (condition of ionospheric scintillation ) was less than 0.25 over Bandung.
The ionosphere activity for the next 24 hours is predicted to be quiet.
The error positioning was medium for the last 24 hours based on W index value.
The probability of error positioning for the next 24 hours is slight during daytime and nighttime based on the W-index value that going to be 2.
MUF depression were in moderate condition and Short Wave Fadeout (SWF) were in quiet condition for the last 24 hours.
The electron flux in the last 24 hours was around 1000 particles/cm2.sec.sr or in the high level. High electron flux is expected for the next 24 hours.
The flux of high-energy proton was quiet due to the extremely low solar activity. Based on today's solar prediction, the flux of high-energy proton is predicted to be quiet for the next 24 hours.
