Description:
In Scorpius, ~ 2° W of Antares (Alpha Sco). After several minutes of careful
observation, the secondary star remains invisible to my binoculars. It shines
less than 100x than the primary star. I had a feeling to catch the secondary
star at right position angle, but this observation is too uncertain to consider that
this component was seen individually. The primary is white.
