According to the monitoring of the Institute of Applied Geophysics. Fedorov Roshydromet integrated solar activity on March 13 was moderate.
On the Sun observed five groups of spots. Again after a two-day lull before hiding behind the western limb of the Sun, more active group of sunspots 1429. At 21.41 MSK there was an outbreak of class M7.9 (almost on the threshold of the highest class X), which was accompanied by a coronal mass ejection, streams of protons over a wide energy range.
Therefore, the geomagnetic field is from the unstable to slightly perturbed, and radiation environment from slightly perturbed to unperturbed. During the day it is better to refrain from airline flights in parts of the North and South poles, where radiation levels may be elevated. Possible disruption in navigation and radio during the day. Expected effects in the polar cap absorption (PCA), again will be highly likely auroras.
