The eruptions on the Sun were due to the superactive sunspot AR2975.Flashes with
Sunspots are dark areas on the Sun that are about 1,500 K cooler than the surrounding photosphere.They are visible on the disk of the Sun in the form of dark spots.Sunspots are areas where strong magnetic fields enter the photosphere.
Sometimes these outbreaks are associated with emissionscoronal mass events (CME), or streams of charged particles that are ejected into space. A NASA observatory recorded what the eruptions look like. Images from March 28-29, 2022 show the glow of one of 17 flares from the active sunspot AR 2975.
Modeling suggests that the particles can generate moderate geomagnetic storms - G2 or G3 - although the auroras (Northern Lights and Aurora Borealis) are still difficult to predict.
It is expected that in 2022 the activity of the Sunwill be relatively low, since the 11-year solar activity cycle is just beginning now. It usually starts with fewer sunspots and fewer eruptions. Activity should increase as it nears a peak, which is projected to occur in mid-2025.
