Aurora-sparking sunspot comes back for yet another trip across Sun, are more cosmic surprises expected?

A hyperactive sunspot that has come in different forms previously, has now again come back with a colossal solar flare a few days back. This is reportedly not the first time the sunspot has shown intense activity. The last time this sunspot was responsible for a colossal geomagnetic storm spread out across the world, creating some gigantic and epic auroras in far ends of the world.

Sunspot's return can trigger solar activity, feel researchers

The AR3723, which is the third-version of this returning sunspot, is expected to trigger some intense solar activity in the coming days, much like the last time its previous subtype AR3697 caused 28 M-class flares and 6 X-class flares, says Yahoo News. This will be a rare third trip for the sunspot region across the Earthside of the sun, and as it faces the Earth, there may be some colossal solar activity.

What can the sunspot's return for the third time mean?

The sun's rotational period happens more or less after 27 days, which means the Sun's active region can be viewed by the Earth for roughly fortnight. Interestingly, as the sun's magnetic field is about to flip, the sunspot region, which is just a fraction of the size its previous versions were, will trigger some magnetic phenomenon, in order to produce powerful solar flares towards the Earth. On June 23, an M9.3-class solar flare was released at 9.01 am ET, and was a little below the levels of the most powerful class of solar flares known about. According to physicists working around the solar angles in the cosmic universe, the M9.7 solar flare was just 3% short of being classified as an X flare.

Aurora chasers excited due to solar activity chances

Space boffins will be keeping a close eye on this particular region as some more unworldly experience is expected in a short while, says Yahoo news. Since there were auroras caused due to the sunspot's hyperactivity in the previous instances, aurora chasers on Earth are all eagerly expecting some solar activity that may lead to more auroras within these days.

FAQs:

What is the coined term for third-time returning sunspot?
AR3723 is the coined term for the sunspot that returned to face the Earth on June 23, for the third time. In previous instances of it's Earthly approach, it had different names.

Can AR3723 cause solar flares?
Yes, AR3723 has a chance of causing epic auroras and solar flares as the last time similar sunspots approached the Earth, similar phenomenon happened.
