An extensive list of CCD magnitudes was published in Henden and Honeycutt, PASP,109,441,1997. This version, a subset of the original list, is newly recalibrated by Arne Henden in 2001 from the original data and extended at the bright and faint ends from the same data set. 2. Two bright Tycho-2 stars in this field, one at 13h 43m 28.6s -08d 10' 11" with a reliable magnitude of 9.78+/-0.03, and another at 13h 43m 28.7s -08d 18' 34" with a reliable magnitude of 10.75/-0.08. 3. There are three stars common with Misselt, PASP,108,146,1996: ID Henden Misselt V B-V V B-V 3 13.526 0.814 13.452 0.775 6 14.797 0.590 14.861 0.597 10 16.044 0.594 16.110 0.606 Bruce Sumner 16 October 2001 Revised 8 February 2002
