On June 17h at 22h23 I was out on the patio observing the moon and planets.Suddenly a huge orange light appeared from East toward North-West. I had neverseen anything alike. The object looked round and was really huge. On top was a hallo like form. It is difficult to determine the height because the sky wasclear with no reference to the clouds although an airplane passed a whileafter and appeared higher that what I had seen. The object was moving fast,no sound nor no trace were detected. I searched for the ISS orbit and determined it wassituated over Sumatra very far away from my city. For me this constitutesa very mysterious phenomena since I have been an astronomer for years.I never had time to grab my camera hence no pictures.
