Hurricane Hilda is churning in the Pacific and heading towards Hawaii where we live. Earlier in the day on August 10th, I was checking the National Weather Service discussion about what was happening/projected and the report said there had been an outburst of intense lightning in the storm this afternoon. Putting two and two together I wondered if the storm was close enough to be captured by the CFHT (Canada France Hawaii Telescope) CloudCam atop Maunakea. But more than that, I have also been on a never ending mission to see some sprites (https://en.wikipedia.org/wiki/Sprite_(lightning)). I wondered if there was any chance of capturing them? So last night, after the Sun had set and some time had passed, I logged on to the CloudCam site to check the most recent two-hour timelapse loop, and sure enough, WE HAD SPRITES!!! The attached image is a compilation of all of the frames in the video (also attached) where sprites are visible. I did some image processing to enhance the contrast and pull out some more detail.

Looks like the cloudcam captured something much rarer than sprites because these look more like Gigantic Jet Lightning. Ill check with some experts and let you know.

I just got confirmation by Oscar van der Velde that these are indeed Gigantic Jets. According to Oscar, Tropical Cyclones are a good place to look for these types of events.

Either sprites or Gigantic Jets also were visible the following evening on the CFHT CloudCam.
