Observing Specialist: R.McMillan
Another rainy and humid night, although not quite as much rain as the previous night.  We also had a problem with the tertiary mirror which we hope can be fixed tomorrow.  Despite being closed, it was a pretty busy night working with the visiting instrument in preparation for a chance to go on sky.
