Bülletään

The solar activity has been quiet over the past 24 hours. The sun is currently spotless and the X-ray flux remained below B-level. Solar activity is expected to remain at low levels for the next 24 hours.

No Earth-directed coronal mass ejections (CME) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux remained at background levels over the past 24 hours and is expected to remain at low levels.

The wind speed first reached about 430 km/s and then slowly decreased to about 380 km/s, the total interplanetary magnetic field remained below 5 nT, and the Bz component varied between -4 nT and +4 nT (as recorded by ACE). The solar wind parameters may show some minor enhancement for next period due to the possible effect of a southern coronal hole of negative polarity that was facing Earth on August 18.

Quiet geomagnetic conditions were observed. Quiet conditions are expected for the next period, with small chances of short periods of unsettled conditions.
