Sun Spot Animation From Austria
We have just received the following animation from Hold Siegfried of St. Marein in Austria.
It was captured with The Imaging Source DMK 31AF03.AS astronomy camera and Schiefspiegler 300/6000 telescope with an Astronomik green filter. 12 films were captured, each one with 1500 frames. The resulting data was processed with Registax.
The images were captured on August 27, 2007 between 08.23 and 09:03 UT.
You thanks go to Hold Siegfried for this impressive little animation.

This is great, thanks for sharing. Do you have a website?

Excellent animation. You clearly see a double movement: the granulation near the spot moving outwards, the cooler gas in the penumbra falling back inwards. – Dankeschön nach St. Marein! – Der Alamak

I’m trying to reach Hold Siegfried to ask him about some of his lunar images? I can’s seem to find a viable email address for him. can you please send me his email address — or at least send him mine?
clear skies,

Jonathan…
I am still trying to reach Hold Siegfried. the need is urgent, because we want to reproduce his image of the lunar feature Sulpicius Gallus in the next issue of Sky & Telescope. the image appears here:

we will pay for such use — but I need to hear from him soon!
thanks,

On June 11, 2008, I sent Hold Siegfried an e-mail, asking him to contact you. It is now his responsibility to take up contact, if he wishes.
