Hi Thanks to Tony for spoiling me by sending me predictions for ETS-6 and after I modified my PIP program for giving me fractional seconds on my old laptop I did some observing of ETS-6 on Thursday evening. The output below is direct from my PIP program with comments and measurements edited in afterwards. Sometimes flash measurements are missing (eg. equating to 32.8 secs rather than 16.2 secs between measurements) - this is where I missed a flash for various reasons eg. setting tel. focus, not concentrating, etc. Towards the end I had trouble with the satellite going behind tree-tops. I started observing late after getting back from a meeting. When the satelite was first aquired, it was already flashing.
