Giant Sunspot AR2192, Easy Viewing Target, Unleashes X class Flare

Giant Sunspot AR 2192 is big enough to be seen without magnification, just using eclipse viewing glasses. I could easily see it this afternoon with just eclipse glasses over the past few days. I did get the scope out today as well, as you can see above (EldestOne’s High School graduation activities took priority over solar imaging I’m afraid).

Sunspot AR 2192  is readily visible in  other safe solar projection systems. The following link will show you several methods to make pinhole projection systems.

You can also use binocular and telescopic projection systems. This link will show you how to make safe solar viewing and telescope projection systems. Here is my step by step guide to making a binocular projection system, and a guide to aiming your binoculars or telescope when you can’t actually look at the Sun. And this is the projection system I use with my refractor telescope.

Sunspot AR 2192 unleashed an X3.1 flare this morning, but sadly there was no coronal mass-ejection with it, so auroral displays are unlikely. As big as Jupiter, this is the biggest sunspot of this current solar cycle, and the largest since sunspot 486 11 years ago. 

The is still a chance that this massive sunspot will produce an auroral-effective flare before it rotates away, but don’t get your hopes up.
