Kubanek (ASU AV CR ndrejov & ISDC Versoix) on behalf of a larger collaboration report: "The 0.6m BOOTES-IR telescope, located at IAA-CSIC Observatorio de Sierra Nevada in Granada (Spain), observed the SWIFT error box for GRB 060926 (Holland et al. GCN 5612) starting at 18:48 UT (2.0 h after the burst) in R-band. We do not detect the optical counterpart during the first hour of observations down to a limiting 3-sigma magnitude of R ~ 20.3. Further analysis is ongoing. This message is quotable."
