A magnetic storm may start on Earth during the day.

Weak magnetic storms are possible on Earth during the day due to the impact of the coronal hole on the Sun. This was reported by the Laboratory of Solar Astronomy of the IKI RAS and the ISSF SB RAS in their Telegram channel.

According to scientists, the probability of disturbances is estimated as moderate, but noticeable.

"In terms of geomagnetic activity, a small coronal hole is approaching the area of action on Earth, which is now visible in the center of the solar disk (slightly to the right). Against this background, the models have calculated today even a 50% probability of weak G1-level storms, which, in fact, means whether there will be or not. In any case, the geomagnetic indexes should at least increase," the report says.

At the same time, new spots were recorded on the surface of the Sun, which had little effect on the observation charts. However, astronomers do not expect a serious surge in activity yet.

"As a result, the graph of flare activity transformed from a straight line into a small comb — several weak, barely discernible flashes occurred. It seems that this will end there — the spots do not show signs of further growth," the scientists emphasize.

Despite possible storms of the G1 level (the weakest class), they usually do not cause serious electronic malfunctions, but they can slightly affect the well-being of weather-dependent people.

Have the vagaries of space weather become record-breaking and what consequences can we expect from them?

Head of the Laboratory of Solar Astronomy, Space Research Institute (IRI) On March 5, RAS Sergey Bogachev predicted the complete absence of magnetic storms on the Sun in 2028. According to him, it is coronal holes that cause magnetic storms on Earth during declines in solar activity.
