Yesterday's powerful solar flare could trigger northern lights in mid-latitudes.

Yesterday there was a fairly powerful flash in the sun. Flash power, according to the official classification - X1.6. According to experts, such flashes occur very rarely, and if we consider that the emission of plasma was directed towards the Earth, the event becomes a piece, if you can put it that way.

According to official data, the plasma ejection velocity is 3,750 km / s, and if the plasma were not decelerated due to the interaction with the magnetic and gravitational fields of the Sun, then the “shock” wave would have reached the Earth already today. However, the actual period is 2 days, the plasma should reach the planet on September 12th. More specifically, September 12, at 17-22 hours Moscow time.

On this page you can see the model of the arrival of the shock wave from yesterday's flash. Apparently, the Earth is just at the center of the blow, although, of course, there is a possibility that there are inaccuracies in the model and the plasma will pass by.



If the geomagnetic disturbance index exceeds 7, then the northern lights can be observed up to 50 s. latitude. You can follow the index here .
