Discoveries using the telescopes on Mauna Kea

[TomK]

I posted something about this event in the hurricane season 2017 thread, but it seems appropriate to post about it here. One of the Gemini North Cloud Cam cameras, used to monitor weather conditions, also captured a phenomenon which some are calling "gigantic jets", although I prefer the term "super sprite". These are electrical emissions that occur above a thunderstorm rather than the usual lightning that occurs within the cloud or goes between the cloud and the ground. This article includes a beautiful enhance image of the event from last week. These things are rare, so it's very unusual for an observatory on MK to capture such an image.
