Guys, this is not a normal UFO. Its like a drone, but its soul purpose is to create cloud cover for UFOs. I saw 4 such things create 4 cloud tunnels above Rapid City, SD back in 189-1990, then glowing bus size UFOs shot through them. I believe this is a cloud maker drone, either learning or testing its new tech...much like a new printer printing out a test page or two before it starts normal work.
The cloud maker itself can only be seen partially with the help of infrared filters, for example I saw one in Taiwan when using an old sony cam with an ir filter on it. I caught it only for 1-2 seconds, but what I saw was a three arm star that turned on its end like a wheel, churning the clouds as it moved through it. I believe that is what made these clouds in Russia...a alien drone whose soul purpose it to create cloud cover for UFO activity. SCW

"Unusual" clouds over Vladivostok attracted the attention of users of social networks. The most popular version of the appearance of clouds - UFO (MULTIMEDIA) Photos from the event from other sources. Unusual clouds over Vladivostok. Photo by: Screenshot Instagram user @primdesign
Vladivostok, February 19, PrimaMedia. Users of popular social networks Twitter and Instagram got a surprise today, February 19, with the appearance of unusual shaped clouds in the sky over Vladivostok. In the photos, which appeared on the Internet more than a dozen tweets, and videos can be seen depicted quite remarkable "white circles", which immediately began to ascribe extraterrestrial origin, RIA PrimaMedia.
Unusual cloud appeared over Vladivostok at lunchtime and instantly became an eye camera lens and gadgets of many citizens. Some expressed concern, if not a UFO has left its mark. Others argue that these bands could leave the plane.
Unfortunately, the editors failed today to receive comments from meteorologists and physicists to discuss what could cause such an unusual form of clouds. Sure that all the laws of physics could explain it all, for example, thereby "effect of the Prandtl-Gloerta", which is most often remembered today internet users. We are talking about the origin of the clouds after the plane. All the same plane?
The emergence of the cloud due to the effect of the Prandtl-Gloerta depends not only on the speed of the aircraft, but also on the temperature and humidity. In normal or slightly elevated humidity cloud formed only at speeds close to the speed of sound. In extreme humidity effect can be observed at lower (transonic, "transonic") speeds.
