The October magnetic storm will begin a day later and will be weaker than expected

Scientists have adjusted the forecast of a multi-day magnetic storm. In particular, the duration of excitation of the magnetosphere after a storm has been reduced in the new forecast from three to one day.

The G1 class magnetic storm will begin on Thursday, October 22, not the 21st. According to experts, there will be no increase in capacity to the G2 level, which was previously forecasted for October 25. Also, the duration of excitation of the magnetosphere after a storm has been reduced in the new forecast from three to one day.

The storm will last until October 25th. Its power will be at the lowest G1 level throughout its length. At the same time, scientists recalled that there are five levels in the classification of magnetic storms – from G1 to G5. Thus, a weak storm can provoke minor disruptions in the operation of power systems, as well as affect the migration routes of birds and animals.

Stronger storms cause disruption to shortwave communications and navigation systems, as well as power outages in industrial networks. In addition, increased solar activity, which usually causes magnetic storms, can cause auroras to be seen at latitudes more southerly than usual.
