    Observed these in close proximity this morning our time moving almost in parallel.
    
    
    Calsky predicted shadow exit of both of these objects at just after 1618 UTC.  Unfortunately I was using my cellphone for timing and it does not measure seconds, not at my best at 4 o'clock in the morning and found my GPS which times in seconds later on!  I have checked that my phone's accuracy is OK within less then a minute and I timed the exit at 1616 UTC. 
    
    As predicted the module faded rapidly with Tiangong reducing much more slowly.
    Sorry that this won't be much use for predictions but I thought some information was better than no report at all.
    Hoping to do better tomorrow morning when there will be about 15 minutes separation but cloud may be an issue.   Observations unlikely the next morning owing to a forecast deluge!
