Abstract: | I present the search for V, R, I rapid optical variability of three gamma-ray loud blazars, 3C 454.3, 1ES 1959+650, 1ES 2344+514, performed at the Loiano telescope. The source 3C 454.3 was observed during the decline of the May 2005 outburst. 3C 454.3 and 1ES 2344$+$514 showed rapid variability in one band at least. The data in this work and archival data support the correlation between the occurrence of rapid variability and the flux variation suggested by Howard et~al., AJ 127, 17 (2004).
