Posted by Steinn Sigurðsson on February 19, 2010 NASA’s SDO destroys a Sundog on launch.
Cool video.
The Solar Dynamics Observatory was launched, successfully, Feb 11th.
On the way up, the rocket crossed a high altitude layer of ice crystals – a wispy cloud – which was showing a Sundog – the rocket visibly rippled the cloud as it passed through – looks very cool.
Full launch video – ripples at ~ 1:50+
Wait, where was the sundog?
Glint to the right of the rocket trajectory as it crosses the cloud – “SDO video link” short video shows it slightly better.
And some say there’s no evidence that human activity has atmospheric effects!
Seriously, that’s so rare, what are the odds of it happening on a solar mission? Hmmm. Sounds portentous.
