Guziy  \n(IAA-CSIC),\nB.A. Allen (Vintage Lane Obs.) and P. Yock (Auckland Univ.) report:\n\nWe have observed the afterglow of GRB 091018 (Stamatikos et al. CGN\n10034) with the 0.6m Yock-Allen telescope (BOOTES-3) located in\nBlenheim (New Zealand). A combination of 21x30s unfiltered images with\nmean epoch Oct. 19.625 UT (18.2 hours after the burst) shows the  \nafterglow\nat a magnitude of R=20.0+/-0.3. The photometry has been obtained using\nas comparison 5 USNO-B1.0 stars. This magnitude implies a rough\ndecay slope of alpha = 0.7 +/- 0.2 (with F ~ t^(-alpha)) as compared to\nthe values of Filgas et al. (GCN 10039). Further analysis is ongoing.",
