The Geostationary Operational Environmental Satellite-16 (GOES-16), operated by the National Oceanic and Atmospheric Administration (NOAA) has picked up some really concerning data. According to its X-Ray Flux readings, two sunspots on the eastern limb of the Sun have been exploding without a pause and erupting M-class solar flares in the process. These solar flares are still not entirely Earth-facing but even then, the Earth has been facing a rolling series of blackouts across all its longitudes. These two sunspots also include AR3310 which produced the nearly X-class solar flare on May 16. There is a significant concern that high solar activity can lead to a major solar storm event.
As per a report by SpaceWeather.com, “ Earth-orbiting satellites are detecting an almost non-stop fusillade of M-class flares so closely spaced they overlap in time. Pulses of UV radiation are ionizing the top of Earth's atmosphere, creating a rolling series of shortwave radio blackouts around all longitudes of our planet. Ham radio operators may notice a fluctuating loss of signal at frequencies below 20 MHz”.
According to the satellite data, there are two sunspots that are causing these hyperactive solar flare eruptions. First is AR3310, which has been already mentioned and is the larger and more powerful of the two. The other sunspot is AR3311 which is far more unstable and has produced the majority of the M-class solar flare eruptions on the Sun.
The two sunspots are expected to face the Earth over the weekend and will become fully geoeffective. It is also believed that an X-class solar flare eruption is possible in the duration when they remain geoeffective. This can generate an extremely powerful solar storm.
