WDS HJ 3213 – Double Star in Aquarius

300 seconds on T13 – Siding Spring – July 21, 2017

WDS lists separation as 29.0 arc seconds, and position angle as 70 degrees.

I calculate, using Astrometrica, the position of the left star as [23 47 07.15, -16 44 14.2 ], and the position of the right star as [23 47 05.29, -16 44 23.6], which gives a separation of 28.32 arc seconds and a position angle of 70.6 degrees.

WDS HJ 3215 – Double Star in Aquarius

300 seconds on T13 – Siding Spring – July 21, 2017

WDS lists separation as 18.5 arc seconds, and position angle as 264 degrees.

I calculate, using Astrometrica, the position of the left star as [23 47 09.65, -16 47 58.0], and the position of the right star as [23 47 08.33, -16 48 00.3], which gives a separation of 19.1 arc seconds and a position angle of 263 degrees.
