Tonight is my last night at JCMT. Things have gone well and I’ve got most of the data I wanted for my project. The weather has been very helpful, with only one night that was too good for my project. The forecast for tonight looks as if it was pessimistic at this point, so I should be able to finish off the last bits before I go home.
The last night of an observing run is a bit like the end of term at school. You’re tired, but buoyed up by the knowledge that some relaxation is ahead. And there is the prospect of getting down to sea level and a real atmosphere with intoxicating levels of oxygen. The trip down is almost like a drug, as your chest can relax, as breathing stops being a chore, an finally your oxygen starved body gets what it needs.
It doesn’t last long, but I think coming down from the mountain is a pretty good drug. Maybe observing is addictive?
