In the past week, Earth has been struck by Earth due to several solar storms which were triggered by the Sun. Why, all of a sudden, have the rate and intensity of Solar activity increased?

Another power outage occurred around Asia and Australia after over a week, when a shaky sunspot sparked a “double solar flare” on Monday, April 25, which would make the sun stronger than usual.

A solar cycle or solar magnetic activity cycle, is a five-year cycle at which solar activity is measured by varying the number of sunspots observed on the Sun’s surface.

The eruption was very intense because it generated an “overlapping pair” of M1-class flares capable of emitting electro-magnetic radiation.

The sun peak is when the sun has the highest number of sunspots (active regions of solar flares).

Although there was no CME from the solar flare that was heading towards Earth, both flares were causing a prolonged radio failure in Asia and Australia, particularly targeting lower frequencies of 20 Megahertz (MHz).

We are now in solar cycle 25, which started in December 2019.

Solar cycle

The solar cycle or solar magnetic activity cycle is a nearly periodic 11-year change in the Sun’s activity measured in terms of variations in the number of observed sunspots on the solar surface. (wikipedia)
