Middle of the day with clear blue skies. I was driving south on I-69 and looked up and saw a small, tic-tac or cigar shaped light in the distance that looked at first like the sun or something was reflecting off of something. I caught it for a few seconds thinking the reflection would stop and I’d see a plane, but instead, it dimmed and shrunk and disappeared quickly. Absolutely nothing in the sky where it was. Then 2 min later it showed up once more, bright, then shrink again and disappeared. It definitely was NOT a plane or drone or anything familiar. Almost like it was something that was able to cloak itself to be invisible.
