Bülletään

The Sun is currently spotless and did not produce any B class flares or higher over the past 24 hours. The chance for a C flare in the next 24 hours is estimated low. However, former region 2731 (currently N15W45) produced a small dimming yesterday. But, no associated Earth- directed CMEs were detected in available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours, and is expected to stay at nominal levels for the next 24 hours.

The solar wind speed near Earth as registered by DSCOVR gradually decreased from about 525 to 500 km/s over the past 24 hours, following the influence of a solar wind stream associated with an isolated negative polarity coronal hole. The Interplanetary Magnetic Field (IMF) was around 5 nT. Bz varied between 4 and -4 nT.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels are expected over the next 24 hours.
