Details:

As the hot and dry summertime peaks in the center of Europe, this season finally brought some strong MCS storms visible far from the Seč reservoir. And then came my opportunity to capture some Red Sprites just by the DSLR camera. I was waiting almost 3 hours until I finally succeeded - even if it was in strong moonlight. This one at 0:17:01 UTC (June 6th) was visible even by naked eyes! Used Canon 6D IR Baader Mod, Samyang 24 mm, f2.0, ISO 3200, 3 seconds exposure, tripod.

Hi! Wonderful capture. Do you happen to know how far away were the thunder clouds? Hoping to catch these myself some day..

Hi. Not only that - I had actual datas from Eumesat MSG, which told me the direction I should try to capture. The MCS storm was above Germany and was moving to me on the border of the Czech Republic. Red Sprites occur about 50-90 km and the center of the storm was 400-200 km from me. I estimate 300 km. But there is also another observation from Martin Popek from Nydek, su I presume it can be calculated very precisely. Here is the satellite image: http://www.astronom.cz/horalek/wp-content/uploads/2015/07/MCS_MSG_6July_0015UT.png and the flashing detection: http://www.astronom.cz/horalek/wp-content/uploads/2015/07/JSCELDNiew_MSG_6July_0015UT.png

OK, so very bad estimate - it even much closer - about 170 km from me, Martin Popek had it 424 km from him (his site is about 200 km from me to the east). He measured it precisely from his site.

Thanks for posting such a great sprite picture with time and location detail! I try to correlate well documented sprite pictures like yours with riometer and magnetometer data for further research.
Thank you!
