FOURTH UPDATE ON ORFEUS MISSION
Special Notice #54: Fading of 1544+28A R CrB
August 6, 2007
R CrB: 15:48:34.41 +28:09:24.3 (2000.0)
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.
Alert Notice 205: Outburst of 0749+22 U Geminorum AND 1900-01 Nova Aquilae 1995 AND Request to monitor 1544+28a R Coronae Borealis AND Monitoring of 0900-31 T Pyxidis AND Monitoring of the old nova 0324+43 GK Persei [V1425 Aql]
