The DIMM seeing monitor was not functioning all night. Normally this would not be a problem, but because the first-half observer was observing crowded fields in the Galactic plane, we were unable to get seeing estimates until we took a few images from our second-half program. Because we use the seeing as part of our decision tree for which targets to observe, that cost us a few minutes (maybe 10 minutes?) in which we could have been observing higher priority targets.
