A Tiny Sunspot! First sunspot in 28 days!


I was alerted this morning by http://spaceweather.com/ that this tiny sunspot had broken the 28 day drought of sunspots. Since I am participating in the Citizen ToM Project (Transit of Mercury) I broke out the necessary equipment and took some short videos (20 sec) while the Sun was still less than 30 degrees above the horizon this morning, November 1, 2019 at 9:28 am PDT here in La Pine, Oregon.

The Citizen ToM Project is being featured on Sky and Telescope's website. Go here for more information: https://www.skyandtelescope.com/astronomy-news/citizen-tom-mercury-transit/

Normally sunspots are numbered but this one is so new and it is so uncertain how long it will last that they had not yet given it a number yet.

Here is a negative view of the same image which makes the sunspot white:


Here is a full Sun image of it. It is in the lower middle left side...
Yes, it is hard to spot!

Here is the Solar Ham website image of the same showing the locality of the sunspot:

And Solar Ham's close up of the sunspot area:

When I processed the initial image with GIMP and the Sobel filter the sunspot really popped out!


My images taken with:
Daystar 480mm scope
