more spectroscopy

Back at work in the usual place today. Last week's file move worked out OK, at least nobody is complaining. I ended up on the roof of the Royal Observatory to inspect another spectrometer similar to the one in Poland. The views from the roof are excellent and a visit of the observatory is always great.

We got carried away and bought some lottery tickets. We each got to pick a set of numbers. Ah well, we will still have to go to work on Monday...
