I'm betting it's Vanguard...or one of those wacky unguided early Japanese rockets – Anton Hengst Oct 27 '20 at 18:19

It's probably the SS-520 again at 0.52 m diameter – Dragongeek Oct 27 '20 at 19:13

Yeah, I'd put my money on the SS-520, but I'd have to do some research. Some of the rockets under design, but not yet launched may be even smaller. – Carlos N Oct 28 '20 at 12:40
