I just read the message from Neil Clifford's obs of ERS 2 and the second
object which followed ERS 2.
Just as I wanted to stop observing yesterday evening I saw by coincidence 2
bright mag +2 objects moving from omega UMA in the direction of h&X Per.
Taking a closer look I remarked that the second object (which followed the
first object in 9.4s) wasn't steady at all. It remained quite bright for a
while but suddenly decreased in brightness untill it was invisible. Later
it became as bright again as the first object. Although I didn't have
elements yet I was thinking already on the ERS 2 satellite and its rocket.
The second object must have been the Ariane third stage. It had a flash
period of 44s but it was quite impressive !
