              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
We were closed for a few hours first half due to local rain and continued radar
returns in the area.
I took some echelle biases while the telescope was stationary and while it was in
motion to see if that could produce the banding that has been reported recently. See
files in tonight's directory for /echelle/biases.* The banding was not clearly
produced either way.
Clouds and radar returns closed us early at the end of the night. Moths are back
pretty bad.
