Following the detection of GRB 050717 by Swift/BAT, we obtained six, 5 minute unfiltered images on 2005 July 18.46 UT (24.5 hours after the burst), using one of Tenagra observatory's 0.35-m telescopes with AP6 CCD at Perth, Western Australia. No new source was detected within the XRT error circle (GCN 3636) of GRB 050717 (Hurkett et al., GCN 3633) down to the DSS-2R limiting magnitude...Full Text

Following the detection of GRB 050701 by Swift/BAT (Boyd et al, GCN 3356), we obtained unfiltered images starting 14.7 hours after the trigger, using one of Tenagra observatory's 0.35-m telescopes at Perth, Western Australia. No new source was detected within the 6" radius XRT error circle (Hurkett et al., GCN 3560) down to the DSS-2 limiting magnitude....Full Text

We observed the afterglow location (Fox & Moon, GCN 2734) of the short/soft GRB 040924 (Fenimore et al., GCN 2735) in VRcIcH beginning 16.2 hours after the burst. Using the field calibrations of Henden (GCN 2811) and 2MASS, we report the following magnitudes: ...Full Text

We observed the afterglow location (Da Costa et al., GCN 2765) of GRB 041006 (Galassi et al., GCN 2770) in Bg'VRc beginning 14.9 hours after the burst. Using the field calibration of Henden (GCN 2801), we report the following magnitudes: ...Full Text

We twice observed the error circle of GRB 031026 (Bulter et al., GCN 2429) with the 32-inch Tenagra II telescope beginning 3.9 hours (Nysewander et al., GCN 2428) and 25.7 hours after the burst. We covered 99% of the error circle in four pointings with a total integration time per pointing of 1350 sec for the first epoch and 1500 sec for the second epoch....Full Text

We began observations in Ic of the error box of HETE 2882 (GRB 031026) at 09:30:10 UT (3.9 hrs after the burst) with the 32-inch Tenagra II telescope. 99% of the error box was covered in four pointings, with a total integration time of 1350s per pointing....Full Text

We have noticed a minor numerical error near the end of GCN 2254. Here is a corrected (and slightly expanded) version....Full Text

We observed the afterglow (Peterson & Price, GCN 1985) of GRB 030329 (Vanderspek et al., GCN 1997) with the 32-inch Tenagra II telescope in IcRcVIc on April 2nd and 3rd, in IcIc on April 4th and 5th, and in Ic on April 6th, 7th, 8th, 9th, and 10th. Between April 2nd and 10th , we find that the afterglow faded from Ic = 16.9 mag to Ic = 18.9 mag. Our 1-sigma error bars are typically less...Full Text

We observed the the optical afterglow (Fox et al., GCN 1879) of GRB 030226 (Suzuki et al., GCN 1888) with the 32-inch Tenagra II telescope at a mean time of Feb 27.357 UT. In a stacked series of 14 x 300 second images we find the source magnitude to be Ic = 20.52 +- 0.10 based on 5 stars from the calibration of Henden (GCN 1916)....Full Text

We observed the entire ~73 square arcminute error box of GRB 030204 (GCN 1854) beginning 11.5 hours after the burst (GCN 1856, 1858) in BVRcIc and beginning 38.2 hours after the burst in Rc. Using the field calibration of Henden (GCN 1860), we report the following 3-sigma limiting magnitudes: ...Full Text

We have observed the field of GRB 021211 (Crewe et al., GCN 1734) using the ARC 3.5-meter telescope at APO under excellent seeing conditions but occasional high cirrus. Pointing problems prevented us from calibrating our images using standard stars. In two 2000 second i' images of the GRB 021211 field beginning at Dec 12, 09:19 UT, we detect an object which we estimate has i* > 23 at...Full Text

We imaged 100% of the error box of GRB 021204 with the 32-inch Tenagra II telescope beginning at Dec 5 07:58:37 UT and Dec 6 08:07:35 UT , 0.7 days and 1.7 days after the burst. For both epochs we integrated in the Ic band for 600s in eight pointings . We note that the Galactic extinction along this line of sight is approximately A_Ic = 0.9 mag (Schlegel et al. 1998)....Full Text

We observed fields containing the candidate afterglow of GRB 021112 (GCN 1696) 4 days after the burst in BVRcIc, 6 days after the burst in Rc, and 7 days after the burst in H. Using the field calibration of Henden (GCN 1697) and 2MASS, we report preliminary photometry: ...Full Text

We observed 100% of the 23 arcmin x 13 arcmin error box, but only 90% of the revised 26 arcmin x 9 arcmin error box, of GRB 021113 (GCN 1686) with the 32-inch Tenagra II telescope beginning 2.6 hours (GCN 1687) and 22.3 hours after the burst. For each epoch, we integrated without filter for 1800 seconds per pointing x two pointings under photometric conditions. Due to more favorable airmasses...Full Text
