Scary Solar storm to strike the Earth tomorrow, says NOAA

tech.hindustantimes.com:

Yesterday, the National Oceanic and Atmospheric Administration (NOAA) revealed that despite the active sunspot AR3315 beginning to decay, it could trigger a solar storm on Earth. And just a day later, satellites pick up solar winds that were possibly released from the activity on the sunspot and are likely going to spark a solar storm on Earth tomorrow, June 2. The solar storm is not expected to be a major one, but it can still disrupt wireless communications and cause a radio blackout. Check the details.

As per a report by SpaceWeather.com, “NOAA forecasters say that minor G1-class geomagnetic storms are possible on June 2nd when a stream of solar wind is expected to hit Earth's magnetic field”. There is a suspicion that the gaseous material is likely flowing out from a pair of holes in the Sun's atmosphere. It is not known whether the sunspot is directly involved in this.

Solar winds are not very unlike a CME cloud, which is majorly responsible for solar storms on Earth. The main difference between the two is the intensity of charged particles. Since solar winds are a stream of charged particles released from the upper atmosphere of the Sun,2 they contain relatively less amount of charged particles than coronal mass ejections, which are taken from the surface of the Sun.

However, they are still capable of triggering minor to moderate storms. Such solar storms may not be strong enough to affect mobile networks or damage satellites, they can still cause radio blackouts and disrupt GPS signals. And things can be worsened if these solar winds pick up a CME on their way and combine with it to spark terrifying solar storms.

The NASA Solar Dynamics Observatory (SDO) carries a full suite of instruments to observe the Sun and has
