It was a power-cut. I went into the gallery (3rd floor) and looked out to check if the whole area had a power-cut, it didn't. Then I noticed a glowing aspirin-sized orb in the sky, near buildings, but it seemed quite from my place. It was moving really slowly, such that motion could not be orbserved through naked eyes. I figured that it was a UFO and I started taking pictures. I took 2 pictures and went back in my room. After about two minutes, I went back in the gallery and took 2 more pictures and came back in. After about a minute, I went back out and it was nowhere to be seen, maybe I couldn't see it because of the buildings, as it was lowering. When I checked the pictures, I could see that it had followed a straight-line path and was lowering. I also found another unidentified object in one of the pictures, and it doesn't resemble an orb, it seems more like a boomerang. The orb was glowing continuously, but fading once or twice. I don't remember having been affected psychologically by the sighting.
