Light curves collected in near-IR, optical and UV bands, between 5 March and 2 April 2009 (JD 2454895.5–2454924.5). Blue circles represent the UVOT data in v, b, u, uvw1, uvm2, uvw2 filters. Red diamonds represent GASP data in R, J, H, and K bands. Magenta triangles represent WEBT data in I, V, and B  bands. REM data in V, R, I, J, H, and K bands are represented with black squares. Yellow regions in R-band light curve indicate the peaks of γ-ray activity observed by AGILE.
