This blog will possibly contain interesting information on new developments in astronomy and astrophysics, on the other hand it might just contain my ramblings. You'll have to keep visiting to find out which wins out.

SciMon Diary: Day 8 (week 2)
When I arrived at the detector we'd been in science mode for about 5 hours and that continued for another 7 hours of my shift - a nice 12 hours at a range of ~17 Mpc. I'd been hopeful that we'd stay in lock for the whole of my shift, which would have made things nice and easy, but unfortunately something happened. It did allow me to actually do something in trying to track down the source of the lock loss - it wasn't an obvious seismic event, and various accelerometers on on a variety of optical benches were inconclusive (I had a lot of help to show me what channels I should be looking to perform the diagnostics). By the end of my shift we had some clues, but still didn't know what the ultimate cause was, or whether the same thing had caused loss lock on other occasions. I had learned a fair bit more about the diagnostics software though, and the locations of a variety of optical benches.
