GCN 2107, 2120;\nGarnavich et al. IAUC 8108, 8114; Stanek et al. astro-ph/0304173)\nassociated with the GRB 030329 with the FLWO 1.2-m telescope between\nMay 26 UT 05:00 and May 29 UT 05:00 (57.7 and 60.7 days after the\nburst) using standard R_c filter. The increase in brightness by >0.3\nmag observed by Stanek et al. (GCN 2244) between May 21 and May 23 UT\nwas followed by a decay of ~0.3 mag and then by an increased scatter\nin the light curve:\n\n         UT          R       dR    Filter    Texp\n----------------------------------------------------\n2003-05-26 05:00   21.612   0.06     R     5x900 sec\n2003-05-28 04:50   21.456   0.07     R     4x900 sec\n2003-05-29 05:00   21.617   0.09     R     4x900 sec\n\nThe figure showing the light curve since May 20 UT can be accessed at:\nhttp://cfa-www.harvard.edu/~kstanek/jitter.jpg\n\nWe should stress that we have a very extensive data set for this\nobject obtained with exactly the same instrumentation and this \"jitter\nepisode\" is very unusual when compared to the whole data set and we\nstrongly believe that it is real and it might continue.  Therefore,\nobservations using larger telescopes, also in other bands, are\nstrongly encouraged.\n\nAny use of these data should include proper reference to this GCN.",
