GSC 154:777 (J2000)
RA: 06h 30m 46s
Dec: 5 degrees 18' 11"

This is a two frame movie comparing my recent image of the Rosette Nebula with that of the POSS1 sky survey from the mid 1950's (a useful article describing the POSS may be found here).  The above motion of GSC 154:777 is easily appreciated after 50 years, although it is still quite small by Barnard's star standards.  Between the two frames, the star has moved 2.49", which means a rate of 0.05 arcseconds per year (compared to Barnard's star which moves at 10.3 arcseconds per year).  After I posted this animation, I noticed at least two other stars that have moved significantly in this FOV.  One is GSC 154:211 (RA, 06 31 30; Dec, 05 17 09; J2000), and the other is UCAC 2.0 Star (RA, 06 31 02; Dec, 05 21 45; J2000).
