Solar activity continues to decline
Solar activity continues to decline. The solar background X-ray emission (flare graph) has been below level "C" for about a week. This means that the solar corona, as a whole, is becoming increasingly quiet. The solar cycle trough, when this graph will look like this, is still a long way off, but the trends are quite clear. At least, even the most inveterate dreamers have stopped talking about the possibility of a second cycle maximum and a reflection off the trough.
A slight increase in geomagnetic activity associated with the coronal hole ended on Saturday and was weaker than predicted. Geomagnetic indices did not enter the red zone once over the weekend, although minor disturbances were observed. There were no noticeable auroras, though none were predicted.
The sunspot count is low. Radio emission levels are low.
No disturbing factors are visible on the horizon for four days. Unless something extraordinary happens, we won't even be writing comments during this period—we'll just be providing graphs. A slight increase in disturbances is possible starting Friday due to another medium-sized hole. The likelihood of strong events (storms and flares) in the coming week is considered close to zero.
