Well, at least it's probably not going to be a Carrington event...

I am curious, though. I read about this today on other sites and even though it was hazy out , I thought to take a look myself. Yesterday I took some shots of the Sun through my new-ish 60mm, and did the same today through the haze.

The first shot is yesterday, the 21st; and the second is from today...

My question is this: Is this spot getting bigger in a way I can't see in white light? I realise the Sun emits all wavelengths of light, and being on that narrow band makes me wonder if I need more filters

Thanks for the post nFA, and all the best to you and yours,

Thanks for the white light snaps! It looks to me like the main spot has doubled in extent in the second shot. Remember that only a ~40% increase in radius will ~ double the area. So I think you’re confirming the article. I suggest that you take another look and allow for the poorer conditions of the later photo.

Thank you nFA; forest for the trees... I did take another look (at 2X image size) and I see what you mean. I was looking for everything but the surface area they cover it seems

Much appreciated!
