Hi Marco Yes its MERCURY 2 #23855. When I observed it on the 10 June -- observations still to be processed by Mike - it was about 4 degrees off in azimuth for me. I may be observing tonight - if clear -- been a bit under the weather with chronic sinusitis so supposed to avoid getting cold... 0.1 sec for geosats is not a problem - even 1 second accuracy is more than adequate.
