must admit Mrk they moving faster than ive seen before, but they do do "strange" things. Winds are quiet high at the moment though, surface winds are slight but a few 100 ft up they in the 30s i believe so i recon they are fight lanterns
the 10 or so i saw over a period of a few days changed alt and speed a lot, but im guessin as they warmed up they gained alt, but lost speed. Once up high, they gained speed which musta taken the heat out of them so they fell. Sometimes they fell so low they disapeared behind trees/houses before "shooting" back up. Very wierd actions by a paper baloon with a candle init lol.
