Was walking home after work when i saw a very bright light above TB observatory. Took up my cellphone to take a picture.Took the picture, looked down at my phone and when i looked back up the object was gone.Spoke the next day to the people that work at the observatory and they where not on location that morning. Spoke to police and the didnt have helicopters or airplane in the area. I also called the electrical Company and they didnt have any issues in the area that morning. With some help from the people at the observatory we calculated that i was located 1km from the object, the Tower is 30m wide and the objekt above the Tower seemse to be 1/3 of the length of the Tower witch makes the objekt 10m wide.
