Awaiting the sunset

We’re sitting in the control room of WHT awaiting the sunset. Before sunset we should take some calibration data and finalise the list of candidates. New candidates are sent to us by e-mail all the time. Tonight we’ll have a go at some candidates we didn’t observe yestereday or need to get an additional spectrum of. There are som very faint challenging targets we still haven’t decided whether to include or not. The wheather is much better to night. Almost no clouds at all. This is going to be an exciting night!
