ISS, Tiangong, Satellites Over Puna

Mermaid - the flare will only last a few seconds so you'll need to be looking at Jupiter at the precise time! Incidentally, the flare should be about 12 times brighter than Jupiter from Kaloli Pt., so if you can find Jupiter, spotting the flare should be easy.

For those in Hilo, Keaau, Kurtistown and Hawaiian Acres, it will be even brighter.
