A strange spherical object with purple haze and trail/ tail was weaving in and out of the clouds and disappeared.It was an overcast day, I was watching my friend’s baseball game when I looked up and saw an object weaving in and out of the clouds. The object was a spherical shape with a purple haze around it with a purple trail/ tail. The sphere looked like it was emitting electricity to the haze or the other way around. Then it returned into the cover of the clouds and I never saw it again. This occurred at Lajes Air Base on the island of Terceira in the Azores.((NUFORC Note: Witness indicates that date is approximate. PD))
