LBT OSU/ND/UM/UVa Member Observing

LBT at Night by Marco Pedani

These pages support queue observing with the Large Binocular Telescope for the quarter-share block run by observers from OSU, Notre Dame, Minnesota, and Virginia. We began OSURC member observing in March 2008.

Instruments currently available for routine OSURC observing:

LBC Red and Blue
MODS1 and MODS2
LUCI1 and LUCI2
PEPSI in non-polarimetric mode
LBTI and PEPSI-POL remain available only during specially-scheduled cross-member campaigns.

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.
