High Speed Camera at High Altitude Observatory

We conducted a high-speed camera campaign for TLEs (transient luminous events) in Taiwan from 2018 to 2019. We have successfully recorded sprites at the NCU Lulin observatory with the high-speed camera at 5000 fps (frame per second). We have also tried to find better observation sites. Due to the high sensitivity and high time resolution of a high-speed camera, the observation sites require a nearly transparent atmosphere and less light pollution. Recent results of the high-speed camera have shown that the recording of sprite streamer interactions and collisions at 100,000 fps was achieved in U.S. and gigantic jets in 2017-2018 near the north coast of Colombia were recorded at 5,000 fps. In this project, we will use our developed techniques on high-speed camera and analyze the data from the ISUAL payload onboard FORMOSAT-2 satellite. Besides, we will apply for an upcoming campaign at Taiwan high altitude mountain to record the TLEs and contribute our new observations to the sprite community.
