Sorry, but should have added that the computer clock and calendar are correct and the Stellarium location is set to the SE coast of the UK.
I downloaded from MPC the asteroid 2012 DA14 using the above procedure. It all went smoothly but I noticed that on the 15th February Stellarium shows it rising at 17:53 ~ about 2 hours before expectation ~ and some 40 degrees further north of east than expected. I cannot see what I have done wrong. Can anyone help?
