LBT OSU/RC Partner Observing Notes
Date: 2015 January 26 UTC (Night 9 of 9)
Observers: Paul Martini, Suk Sien Tie (OSU)
Support Astronomer: Barry Rothberg (remote) 
Telescope Operator: Steve Allanson

SUMMARY:

Start of night: partly cloudy, coming in from the South, seeing about 1.3. Imaging
with LBC for a while before forced to close due to humidity. Humidity continued to
stay high (and increased) throughout second half of the night. Ended run early.
