[vsnet-chat 1305] V517 Oph sequence


                         V517 OPHIUCHI
                  - Comparison Star Sequence -

For those southerners, like Berto, who would like to monitor the 
rise of this under-observed RCB variable, the following sequence
may help. This is the official VSS RASNZ sequence, and is the same 
sequence used by Kato-san to calibrate the recently reposted vsnet 
chart of this variable (vsnet-chart 100). The sequence was obtained 
by Pam Kilmartin at Mt John Observatory, New Zealand, and was 
originally published in Publ. of the VSS RASNZ, No. 16, p. 16, 1991. 
The J2000 coordinates in the following table are all from USNO A1.0.

Variable: V517 Oph, RCB, 12.6-20.3B
Position: 17 15 19.71  -29 05 37.7 (J2000) (USNO A1.0)
Source:   PEP photometry from P. Kilmartin, 1991
