Castro-Tirado (IAA-CSIC Granada), on behalf of a larger\ncollaboration, report:\n\n\"Following the detection by Swift of GRB 090404 (Ziaeepour et al. GCNC\n9086), the 0.6-m Yock-Allen robotic telescope at the BOOTES-3 astronomical\nstation in Blenheim (New Zealand) responded automatically, under\nnon-favourable conditions (very high airmass). The first i'-band images\ntaken 185s after the trigger time (15:59:35 UT) set a limiting magnitude\nof i' = 15 at this time. Follow-up observations at the 1.5-m telescope at\nObservatorio de Sierra Nevada in Granada have been obtained starting at\n21:46 UT. No optical afterglow in the I-band is detected at the Swift/XRT\nenhanced position (Beardmore et al. GCNC 9088) down to the DSS2-infrared\nlimit.  A more detailed analysis is in progress.\"\n\nThis message can be quoted.",
