TITLE: GCN CIRCULAR NUMBER: 9638 SUBJECT: GRB 090709A: Wyoming Infrared Observatory NIR upper limits DATE: 09/07/09 21:57:07 GMT FROM: Jerry Bonnell at NASA-GSFC/LHEA GRB 090709A: Wyoming Infrared Observatory NIR upper limits Jay Norris (U. Denver), Jerry Bonnell (CRESST/UMCP/GSFC), Tzitlaly Barajas (Los Angeles City College), Amanda McAuley (Cal State U. Los Angeles) report on behalf of the Goddard/Univ. Wyoming NIR camera collaboration. We observed the Swift XRT position reported by Morris et al. (GCN Circ. 9625) for GRB 090709A with the 2.3-meter WIRO telescope and the Goddard IR camera starting 52 minutes after the Swift trigger. Using stacked J- and K- band exposures begining at 08:30 UT, we derive the following 2 sigma upper limits for the afterglow source reported by Morgan et al. (GCN Circ. 9635) from PAIRITEL observations. Tmid (UT) Mag 09:30 J-band > 21.5 09:55 K-band > 18.5 The source is designated source B in the Subaru K-band finder chart from Aoki et al. (GCN Circ. 9634). Our K-band observations were compromised by cirrus. Our upper limits are derived based on a comparison with two field stars with J-band magnitudes 14.5 and 15.7 in the 2MASS catalog. Further analysis of J- and K-band images is ongoing.
