Scientific paper
Dr. Brian Espey (Trinity College, Dublin, Ireland) has requested photoelectric photometry and bright star CCD photometry of the semiregular variable NSV 99 (= khi Peg = chi Peg) beginning immediately. These observations are in support of ultraviolet spectroscopy to be obtained with the Hubble Space Telescope in late October and late November 2009. Observations are requested to continue through the end of November 2009. Photoelectric observers are asked to obtain nightly V-band photometry of NSV 99; comp and check stars are given. Instructions for CCD observers are also given. Observations should be submitted to the AAVSO International Database as NSV 99 or KHI PEG.
