Yup, tonight was a non event, jupiter probably, like I said, seen it before. Having said that, the reason I didn’t get too excited was becuase I have witnessed a lot stranger beyond explanation events. I don’t spend near as much time outside at night as I did in my younger years.about 30 years ago me, my exwife,sister and brotherinlaw witnessed a craft not much higher than treetop level, at dusk but not dark.All 4 of us stared at it for several minutes before it sped off, none of us reported it either, and it wasn’t a plane or helicopter or some kind of balloon.But since that day, I don’t discount anything as to what somebody says they saw.
Instead of guessing at Jupiter, download & install Stellarium. It’s free, and surprisingly good, planitarium program. You can set it for your own exact location.
Loads fast, easy to use (even I can do it!) customizable, and goes to the current time/location on startup.
You can use it prior to going out, so you’ll know where to find what you want to look at; or after the fact, to see if there is a is a star or planet where you saw something like this light of yours.
