V3903 Sagittarii is an Algol variable star system in the constellation Sagittiarus. Its apparent magnitude is 7.31. Located around distant, the system consists of two hot O-type main-sequence stars of spectral types O7V and O9V.〔 Due to the eclipses, the system varies by 0.16 magnitudes in the V-band with a period of approximately 1.74 days. John Flamsteed gave this star the Flamsteed designation ''11 Sagittarii'', although for some reason this designation is now more often used to refer to the star he designated 1 Sagittarii. ==References==
