Huge solar prominence on the sun today. Shot through some high altitude wispy clouds so it is not as detailed as I would like. Also wanted to put a barlow magnified lens on to zoom into the prominence but before I got a chance the clouds became much thicker.
I have included a scaled Earth to give you an idea just how big that prominence was.

Thank you very much No all the photos are this size. What I mean by 60 images in the description is that they are all virtually identical taken one after the other. When you stack these images together in an astronomy image editing program you are able to pull more detail of of the images as it improves the signal to noise ratio.

Really cool Greg!
They said the other day we had one of these solar flares pointing right at us. Not sure if that's a danger but it didn't really sound like good news

Thanks again mate If I remember right I think they were talking about the large sunspot group that was pointing straight at us. The active regions around sunspots are generally where most of the ejections/eruptions come from, so there was a chance that we could get an eruption coming stright at us. The auroras would have been awesome if that had happened.

So amazing! Is that the best one yet for the series Greg?
Nice to see the Prominences as lines on the surface too. Your processing is spot on sir

Thanks for the great feedback Shaun It's the biggest one I have clapped eyes on yet. It's actually still there today.

Wow that is huge. I wonder what effect these have on us. They have to effect us surely.

Thanks 'Tis a big one. If it was pointing straight at us instead of off to the side and there was a eruption or coronal mass ejection then we would get increased aurora activity. A really big ejection straight at us could knock out satellites and power supplies. Thankfully they are really rare and we have a magnetic field that deflects most of it.

So because it's to the side it won't increase aurora activity?

CapturingTheNight In reply to irrationalrationale [2011-11-14 19:04:06 +0000 UTC]
Probably not. As I understand it, these prominences are usually fairly benign. If the surface suddenly erupts and ejects material away from the sun and if it's pointing at the earth at the time, then we can expect increased aurora activity.

thanks. I have big hopes that I will catch it sometime. I am pretty far south, but there is an astronomy field near me which brags the ability to view such things when they are highly active.
so i'm constantly trying to figure out when that is haha

I'm pretty sure there are websites that you can get a text message sent to you if an aurora is predicted for your area. Might be worth looking into.....
