Was stargazing on the balcony, when a weird white light caught my eye. The light, spherical in nature, was moving across the sky eastwards, at about the height of a regular aircraft. It was probably traveling at a speed of regular airplane, but at the same time it did not move like one and there was no noise emitting from it (at the rate of its speed there should have been an audible noise). What was strange was that unlike a regular airplane the craft wasn't flickering. At some point the light was starting to dim, it disappeared from the sky for a short while until reappearing again. The light again resumed its previous action and dimmed out once more,this time however it did not reappear. Unfortunately, I did not have my phone on me to capture and take pictures. I have seen this type of light in the sky previously while in Greece, and while looking up from the same place a couple weeks earlier. I did not make anything of it the first time but it has gotten me interested now.
