V905 Sco, classified as either SDOR or ACYG:, appears to be undergoing a
gradual decline in brightness over recent months.  Monthly visual means are
listed below with the number of observations in each mean shown in brackets.

V905 Sco is currently at its faintest since regular observations commenced
in 1997 March.  A seasonal gap in the data is evident as this field passes
through conjunction with the sun.
