Wasn't expecting anything but the BGO robot fired up and grabbed some data. I guess it was somewhat clear in Halifax.
I had programmed a run for the open cluster NGC 1907. It was on my "view again" list. Oops. I didn't realise that I had already captured 1907, back in September. Guess I forgot to update my ST3P list on John Charles... And I forgot to update the "view again" lists...
I'll have to check closely to see if the data quality is any better. First impression is that it looks the same.
Bound to happen, I guess, this type of mistake. Shooting something again when I don't need to is wasteful for all concerned.
