Note:

In addition to the observing log and the individual instrument data logs, we provide two supplementary plots:

AGw plots guide star image quality (FWHM and ellipticity) and instrumental magnitude [28-2.5*log10(cts/sec)] when observing with MODS, LUCI, and PEPSI. The LBC guiders do not produce comparable data.
Env plots LBT weather information during the night: temperature, relative humidity, wind speed (actual and 5-min running mean), and pressure. Humidity and wind closure limits are indicated with the red lines. [LBT Weather Guidelines]

These may be absent if telemetry is offline or no observing was done.

All dates and times are UTC unless otherwise noted.
