The prototype of its class and characterized by random fadings from maximum light, 1544+28A R Coronae Borealis continues to fade in brightness. Observations reported to the AAVSO indicate that the present fading from its maximum visual magnitude of 6.0 began in early July 2007. Fading slowly to about magnitude 7.0 by July 17, it remained at that magnitude before continuing to fade again on July 22, since when it has declined more steeply, reaching magnitude 10.8 on August 6.
