Category: Multiple star.
Class:
Constellation: Hya
Data: mag 6.73-9.20 size 61.0”
Position: RA 08:38 DEC -06:48
Description:
Very wide spaced, about mag 2.5 difference, easily split at low power. The primary was yellow and the secondary blue. In a change of 8 stars (counting this pair as 2) running N-S. At the S end, 3 of the stars are in a narrow triangle, a sort of Sagitta effect. I measured the separation at 178.4”, PA 178.4d. I obtained some information from WDS: it gives 221d in 1880, and 202d in 1918, so this seems reasonable.
