Sat, 04 Jul 2015 - R Scuti is fading

Recent observations indicate that the star R Scuti is fading into a minimum.

R Scuti spends most of its time within a few tenths of a magnitude of mag 5.4. However, it will often fade into minima. Some are deep and can take it below mag 8.0 ; others only see it drop by a magnitude or less. The general pattern is for R Scuti to have one deep minimum and one shallow minimum in each of its 140 day cycles. However, R Scuti doesn't always obey the "rules" and will sometimes produce consective minima of similar depth.

The latest observations place R Scuti at about mag 6.5, making it borderline between being a deep minimum and a shallow minimum. It may now continue to fade into a deep minimum ... or might brighten again. The only way to find out is to go out and observe it.

You can locate R Scuti and follow its brightness changes using this finder chart. A number of stars are labelled with which you can compare the brightness of R Scuti.
