There are two additional independent photoelectric sequences available for this variable; an extensive 18 star sequence from Karen Meech (PASP, 95, 662, 1983) and an 11 star sequence by Brian Warner (Publ. VSS RASNZ, No. 4, 1976). The AAVSO preliminary chart dated 04/1984 shows all 18 stars from Meech and the VSS RASNZ chart 1104, dated 09/1992, shows all 11 stars from Warner. Note that 97 is mislabeled on RASNZ chart 1104, it is actually 3.0' SW of the marked position. 2. The current sequence contains seven stars that are common to both the Meech and the Warner sequences. The following list shows all stars in all three sequences: ID RA (2000) DEC X Y Meech/ Warner/ Henden AAVSO RASNZ V B-V V B-V V B-V 12 51 06.4 -29 10 39 -1012 258 8.01 0.24 12 52 39.9 -29 01 01 206 835 9.62 0.47 9.64 0.43 12 51 55.8 -29 04 09 -372 647 9.65 1.06 9.68 1.06 12 51 48.6 -29 16 27 -466 -91 10.45 1.04 10.47 1.07 12 53 14.0 -29 09 37 652 319 10.70 0.57 10.72 0.54 12 53 19.8 -29 19 07 727 -251 10.96 0.48 12 52 07.8 -29 02 27 -215 749 11.01 0.47 10.98 0.45 12 51 10.5 -29 06 01 -966 535 11.23 0.48 12 53 04.0 -29 04 45 521 611 11.29 0.48 1 12 52 35.3 -29 12 59 146 117 11.35 0.87 11.41 0.90 11.399 0.899 12 52 49.3 -29 02 54 329 722 11.74 0.53 2 12 52 50.1 -29 15 39 339 -43 12.02 0.94 12.07 0.93 12.095 0.950 3 12 52 40.9 -29 11 41 218 195 12.17 0.60 12.21 0.61 12.223 0.629 12 51 32.1 -29 12 24 -683 152 12.65 0.71 4 12 52 39.4 -29 14 58 199 -2 12.70 1.18 12.74 1.16 12.747 1.185 5 12 52 47.6 -29 10 43 306 253 12.89 1.29 15.04 0.95 12.920 1.331 6 12 52 31.4 -29 14 02 94 54 13.48 0.64 13.52 0.63 13.512 0.664 10 12 52 26.4 -29 16 44 29 -108 15.13 0.96 15.666 0.669 3. Note Warner's discordant value for star #5 (15.04V). It is not obvious what star he actually measured, but it does not appear to be star #5. Meech states that 'this red star could be varying' but this seems unlikely, a misidentification by Warner is more probable. Also note that Meech's value for star #10 (15.13V) appears to be discordant and should not be used. Bruce Sumner Revised 11 June 1999
