CCD Astrometric Measurements of WDS 00023-7238 HJ5439
Abstract
We obtained astrometric measurements of the double star system 00023-7238 (HJ 5439) using the iTelescope network and MaximDL v6 software. We measured a mean position angle of 79.2 deg ± 0.2 deg and an average separation distance of 9.53" ± 0.04"; these measurements show a decrease of 0.4 deg and 0.23" from the last measurement in epoch 1998.50. Historical and current data show no obvious signs of orbital motion, which suggests that HJ 5439 may be a visual double.
