Bad Astronomy: what is Oumuamua?

Best bet is Oumuamua is Manganese (III) which is a supernova product, though where it got the methane-ish ice from is anyone's guess.

I sampled five times and got these results:
1. 4/5 pixel samples ret. as Manganese (III).
2. 1/5 pixel samples returned as dichromate.

What supernova that might have come from is anyone's guess. What the dichromate return means? Anyone's guess.

Update: a slightly more useful image showing the difference between the bright (Methane Ice impacted on the surface) and the dark (Oumuamua).
