Problems: 

There was an interlock broken related with the GCS. Reset did not solve it but Configure did.

When changing to project 2015A-0322 I got an error about invalid Prop-ID. I was surprised since I used that Prop-ID successfully at the very beginning of the night. I soon realized that the semester A was officially over at midnight. I contacted Chris Smith on the phone. He confirmed that was the case and extended the expiration date of the project. Thanks Chris!

Following instructions from Klaus Honscheid, we tried the new sytem of GUIs based on firefox. We used it for observing during about 4.5h. All GUIs displayed correctly and had full functionality. However, after a couple of hours they started to get slower and slower. Observer console and Alarm History crashed once each. Around 12:30 I decided to get back to the Chrome GUIs. Details were sent to Klaus by e-mail.

Dome closed at 1am due to clouds.

Comments: 

I started the Star Flats requested for engineering. However, sky conditions degraded quickly and I decided to stop the script. Only u,r and half g were done. I will repeat the star flats tomorrow if the conditions allow it.
