Giant sunspot doubled in size in 24 hours, and it’s pointing right at Earth | Live Science

A gigantic sunspot has swelled to twice Earth’s size, doubling its diameter in 24 hours, and it’s pointed right at us.

The sunspot, called AR3038, grew to 2.5 times Earth’s size — making the sunspot roughly 19,800 miles, or 31,900 kilometers, in diameter — from Sunday (June 19) to Monday night (June 20), according to Spaceweather.com, a website that tracks news about solar flares, geomagnetic storms and other cosmic weather events.

Sunspots are dark patches on the sun’s surface where powerful magnetic fields, created by the flow of electric charges from the sun’s plasma, knot before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares and generates explosive jets of solar material called coronal mass ejections (CMEs).

A Graceful Solar Eruption from NASA! | greenpacks.org

The phenomenon of solar flares is nothing new. We are already well aware of the 11 year solar cycle that sees this fiery cosmic show ebb and flow and this has been going on for millions of years now.

Currently, we are heading towards another solar maximum; a period that sees a spike up in the solar flare and sunspot activity. And NASA’s Solar Dynamics Observatory has just captured what it dubs as a graceful solar eruption.
