Significant solar flare likely to hit earth on Saturday, could disrupt GPS signals: NASA

A geomagnetic storm is set to hit Earth after NASA warned of a "significant" flare eruption from the Sun.

New Delhi: The Sun shot off a “significant” solar flare which was captured by NASA’s Solar Dynamics Observatory (SDO). The flare came from a sunspot called AR2887 peaking at 11:35 AM EDT on October 28, 2021. 

The importance of the a sunspot is that it determines if the massive solar flare could cause anyharm to earth, and based on its location the flare was positioned in the center of the sun and facing the Earth, Spaceweather.com reported.

"POW! The sun just served up a powerful flare," Nasa tweeted.
