Solar activity was quiet. Neither significant event of flare, radio burst, nor coronal mass ejection was detected for the last 24 hours. Based on the latest observation by SDO/HMI, two small active regions appear on the disk, one of which has not numbered yet. STEREO EUVI/AIA 195 observation shows indication of a new active region to appear from the east limb of the solar disk in the next 24 hours.
Based on today's condition, the solar activity from 20 March 08.00 UT to 21 March 07.59 UT is predicted to be quiet.
The geomagnetic activity was on quiet level for the last 24 hours
Solar wind speed was increased from 350 km/s to 425 km/s. Bz component of IMF was fluctuating from -6 to 8 nT. None of the coronal hole which on southeastern part of the Sun and south pole were considered geoeffective. Substorm activity for the last last 24 hours occured 19 March 2019 at 20:00 UT with intensity around 500 nT and lasted for 3 hours.
Quiet level is expected for the next 24 hours
Ionosphere was in minor conditions for the last 24 hours.
There were no depression of foF2 lower than 30% of its median value. There were increment of fmin more than 30% of its median values for 60 minutes.
The Sporadic-E occurred in the night and daytime for 720 minutes. The W-index mean value was +2 .
The Error positioning was slight for the last 24 hours, based on W index value.
MUF depression was in quiet condition and Short Wave Fadeout (SWF) was in moderate condition for the last 24 hours.
The electron flux was less than 10000 [particles/cm2.sec.sr], which means it was on high level for the last 24 hours.
High level electron flux is expected for the next 24 hours
The flux of high-energy proton was in quiet level due to extremely low solar activity. Based on solar activity predictions, the flux of high-energy proton from 20 March 08.00 UT to 21 March 07.59 UT is predicted to be quiet.
