NASA captures Terrifying solar flare eruption that caused blackouts on Earth
It is not every day that a nuclear blast on the Sun can cause the Earth to shake! But on Monday, October 3, that is exactly what happened. A gigantic filament of magnetism (also known as a solar flare) erupted on the southern hemisphere of the Sun. The solar flare was spotted by NASA Solar Dynamics Observatory (SDO) which recorded it to be an X1-class solar flare eruption. X-class eruptions are the strongest category. And its impact was felt on Earth where GPS disruptions and radio blackouts impacted critical communications in the affected region. But the danger is not over yet. More solar storms are expected to hit the Earth this week which may multiply the damage. But luckily for us, the SDO is monitoring the Sun to record any incoming danger.
The solar flare caused radio blackouts in the USA, which is also dealing with the aftermath of Hurricane Ian. Due to the mobile network towers being knocked out, the rescue operations and disaster response missions were being conducted via radio channels of 25MHz. This frequency was entirely blocked by the radiation and as a result the operations were delayed by hours which could have resulted in loss of life and property.
The Solar Dynamics Observatory is a NASA mission which has been observing the Sun since 2010. The goal of the SDO is to understand how the Sun influences the Earth and near-Earth space by studying the solar atmosphere. It has also been investigating how the Sun's magnetic field is generated and structured, how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in the solar irradiance.
To do this, the SDO uses Helioseismic and Magnetic Imager (HMI) which takes
