CCD B & V Photometry of the Young, Active, Late-type Star PZ Telescopii
We present new CCD B and V photometry, obtained at the BrightwaterObservatory in June and July 2006, of PZ Telescopii (HD 174429), ayoung, rapidly rotating late-type star with an active chromosphere. TheCCD data were collected with a short focal-length telescope, giving afield of view near 0.80 x 0.55 deg, so target and comparison stars couldbe observed simultaneously. A periodogram analysis of the PZ Tel datareturned a value of 0.94 d, consistent with earlier photometry. We foundthe amplitude of variation was ~0.06 mag in B and V, with evidence fora small colour variation of between 0.01 and 0.02 mag, the star beingredder when fainter. From a comparison with previously publishedphotometry we find that the amplitude of V-light variation is amongstthe smallest ever observed. There is an indication that there was amaximum in the long-term brightness level near V=8.28 around the year2000, with the current data being several hundredths of a magnitudefainter.
