Weather Report for February 4, 2011

The night was photometric and still quite cold, although 10-20 degrees warmer than the previous night. The seeing was again very poor, usually 2-3 arcsec with periods of even worse seeing at around 4 arcsec. The temperature is still too cold for the SPOL aperture wheel to behave properly, so a single slit was used for all observations. No photometry was obtained owing to the narrow slit used for spectropolarimetry and the exceptionally bad seeing.
