I was looking the sky in my house this evening when i noticed a pink/red oval shaped object crossing the sky. I believed it was an Airplane at first bit soon i realized that it looked like a spiralic star even if it was very small. The object moved North with a straight path but the speed was irregular. It looked like it was pulsating. It is simply vanished in a cloud reducing his visibility after every red pulse. I couldn't take photo unfortunately.
