I just put my solar filter onto my telescope to take a look - and there's a HUGE sunspot right now.

NOTE: DON'T ATTEMPT THIS IF YOU DON'T HAVE A PROPER SOLAR FILTER!!!!!

The attached quick photo was taken hand-held with my phone held at the eyepiece.

Checked on http://www.spaceweather.com/ and - Yep! It's big alright!

BIG SUNSPOT FACES EARTH:
The rapid growth of sunspot AR2396 is continuing. Yesterday it was huge. Today it is 50% larger.
...
The growing sunspot group stretches more than 150,000 km from end to end. All by itself, the primary dark core is more than three times the size of Earth.

Julian, That is the sunspot I captured a couple of days earlier when photographing an ISS transit, (see pic this forum)
Very interesting to see its growth. Well done!

Thanks for that, Julian! I hadn't heard about it yet so I just had a look and was even able to capture it with the Neximage. I haven't really processed the images yet (I just selected a couple for this thread), but it was fun! At least it was not too cold with the sun in front of me. :) I haven't got time now to look at all the images and process them, but if some turn out nice I will post them later this week...
I think this spot looks like a snake...

I wonder if it will grow even more?

Nice catch with the ISS!

Apparently AR2396 is a naked-eye sunspot (with the right viewing conditions / eye protection, of course!) Check out:

I had a look at lunch time through some solar filter and yes I was just able to see it naked eye. Pretty cool. :thumbsup:

Cheers
