Weather Report for March 17, 2010

Very light and very scattered cirrus that doesn't show up on the IR weather map pushed over Arizona throughout the night. This made photometry a hit-or-miss affair. Spectropolarimetry was never seriously affected by these pesky little clouds. The night was windy as was the previous night. The seeing was more stable than during the previous night, but it still wasn't very good (about 2 arcsec).
