Solar flaring activity was at low levels over the past 24 hours. There are five active regions present on the visible solar disk, with a newly emerged region located on NE. Two returning active region are about to rotate in the visible part of the disk on SE. NOAA AR 3085 has been the most energetic, exhibiting growth and producing the largest flare of the period, a C2.4-class flare, peaking at 21 August 23:47 UTC. Flaring activity is expected remain mainly at low levels over the next 24 hours, with a small chance of M-class flares.

No Earth directed Coronal Mass Ejections (CMEs) were detected in the available coronagraphic imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours. The proton flux is expected to remain at nominal levels for the next 24 hours. The greater than 2MeV electron flux was about the 1000 pfu threshold over the past 24 hours. It is expected remain about about threshold over the next 24 hours. The 24h electron fluence was at moderate levels over the past 24 hours. It is expected be at nominal to moderate levels over the next 24 hours.

The solar wind parameters reflect high speed streams (HSS) and ICME influences over the past days. Over the past 24 hours, the solar wind magnetic field values were quite stable, fluctuating between 5 and 8 nT, while Bz had values between -7 and 6nT. The solar wind speed was fairly stable at around 570 km/s, with variations. The interplanetary magnetic field phi angle was on the negative sector (towards the Sun). Over the next 24 hours, we are expecting the impact of those effects to persist.

Active conditions were recorded at 21 August 15:00-19:00 UTC (NOAA Kp and/or K Dourbes 4) over the past 24 hours. Unsettled to active conditions can be expected over the past 24 hours.
