The computer at the Kuiper Telescope that handles the network had a major hardware failure about 1 hour before sunset. Because of this, guiding or viewing the SPOL aperture plate was impossible. About 2 hours were spent trying to get around this major network component, but to no avail. Thanks go to J.D. Berryman for trying to recover from this major problem.
SPOL was configured for V-band imaging polarimetry and the rest of the
night was spent obtaining polarization measurements and differential
photometry of more than a dozen blazars in seeing of around 2 arcsec.
The superb pointing of the Kuiper
Telescope put targets within the 50 arcsec square aperture used for
imaging polarimetry. Hopefully, we'll be back to doing spectropolarimetry
