Because of the report about ea27 it would be useful ot have a focus check
if another gap turns up in the next few days.

focuscheck requires about 40 minutes.  PLease run it in a gap if:
there are no competing requests,
it is not near sunrise or sunset,
it is not too windy,  (5m/s is OK; 10 m/s is not)
and not snowing.
Phase stability is not critical.

Thanks,
