Greenland high-speed auroral video operations

October 20, 2015

Thanks to more great support from the SRI Sondrestrom team and of course NSF, we are once again observing with the amazing Marshall 140mm lens and the Andor Neo sCMOS camera. This gives up to 8 degree field of view with up to hundreds of frames per second. We are starting off with white-light (unfiltered) operations, but will soon transition to a “prompt emissions” BG3 filter to avoid the smearing that happens in high-speed auroral video from long-lifetime metastable emissions.
