We present Keck diffraction limited H-band photometry of a z~1.3 Type Iasupernova (SN) candidate, first identified in a Hubble Space Telescope (HST)search for SNe in massive high redshift galaxy clusters. The adaptive optics(AO) data were obtained with the Laser Guide Star facility during fourobserving runs from September to November 2005. In the analysis of data fromthe observing run nearest to maximum SN brightness, the SN was found to have amagnitude H=23.9 +/- 0.14 (Vega). We present the H-band (approximatelyrest-frame R) light curve and provide a detailed analysis of the AO photometricuncertainties. By constraining the aperture correction with a nearby (4"separation) star we achieve 0.14 magnitude photometric precision, despite thespatially varying AO PSF.Comment: 11 pages, 8 figures, Accepted for Publication in AJ Updated the citations, fixed typo
