Data: mag 4.1 + 7.0 size
Position: RA 16:12 DEC -19:28
Description:
In Scorpius, at ~ 1½° E of Graffias (Beta Sco). I had not observed this double
star for a while, my last observation dates back to May 20, 2001. The brightness
of the primary surpassed, by far, that of the secondary, which complicates the
identification of the latter. I estimate the position angle near of 360°, which
is pretty close to the real value (337° in 1955). The 2 components are white.
