Smith (Liverpool JMU)\nreport on behalf of a large collaboration:\n\nOn 2009 August 14 at 02:57:31 UT the 2-m Liverpool Telescope\nautomatically began observing the INTEGRAL GRB 090814B (Beckmann et al.,\nGCN Circ. 9795) using the g',r' and i' filters.\n\nWe do not detect any uncatalogued source inside the Swift-XRT error\ncircle (Evans et al. GCN Circ 9803) down to the following values:\n\nMid Time   Delay from GRB   Total Exp  Filter   Upper limit\n(UT)       (hours)          (s)                 Magnitude\n-----------------------------------------------------------\n03:26:17    2.08            600         R         > 21.3\n03:27:52    2.11            540         I         > 21.0\n---------------------------------------------------------\n\nMagnitudes have been calibrated from the nearby USNOB-1 star\n04:19:01.476, +60:35:18.11 using R2=18.34 and I=17.14.\n\nWe note the considerable Galactic reddening along the GRB\ndirection: E(B-V)=1.14 (Schlegel et al. 1998).",
