Twilights

LRS2 and VIRUS twilights should be taken at the center of track position. Please take them back to back as quickly as possible. For LRS2 try lsky.sh command found in the /home/mcs/astronomer/bin/ directory when GC2 counts reach 62k when viewing the raw GC2 images if there are no clouds and 35k if there are clouds. For VIRUS use the vsky.sh command found in the /home/mcs/astronomer/bin directory when GC2 counts reach 6.6k when viewing the raw GC2 images. Report any saturation issues.

Priorities

• Open dome engineering tests
• Closed dome engineering tests
• Science targets
• Long cals

Open dome engineering tests

• Check the position on the ACAM for LRS2-B, LRS2-R, BIB and HPF ACQ.
• check the offset from LRS2-B to LRS2-R

Closed dome engineering tests

• Linearity test of GC1 and GC2 with a lamp. Check with constant lamp source to get "cleaned" images with GC1 and GC2 at different exposure times from 1 second to 20 seconds.

• Check what the command is to change the filter for GC1, GC2 and ACQ and if making that command if the g filter is already set.
