Problems:
(1) During the telescope focus sequence, the focus script executed twice. I think this is a bug because I remember this occurring in January. This was using the focus wide script.
(2) Blanco ECS telemetry ¨Telescope Sensors Diagram with Last Values"is not updating on the diagram.
(3) WCS coordinates on the FITS headers were wrong at the beginning of the night. The CRVAL1 and CRVAL2 values were both set to 0. Marco updated the software to read the correct keyword.
(4) First half of night (20:00-01:00) was given over to guider work. The guider team has made progress and will need to send separate report.

During the afternoon, we tested the new calibration lamp system. Two changes were made to the lamp system since January. The first was replacing the lamps with lower intensity bulbs. The second was purchasing KG1 filters that block transmission from 1-2.5 microns to 1% (J) and 5-10% (H,Ks). We used the lamps at 100% intensity for 20s (J), 4s (H) , and 1s (Ks) and obtained peak counts around 4000. Frank Valdes downloaded the flats and made master flats for the night. The flats are fairly level.
Because we were using the lamps at 100% intensity, I would like to have the old, higher intensity lamps installed tomorrow.
