UT: 0025 FollowUp SN2012fr BG + JHK (1h + 1h)

30s acquisition image in J band - SN not visible. Repeated acquistion with 45s exposure. Possible detection but very marginal. Began OB and checked first spectrum for trace. No sign, so cancelled OB and moved to photometry, increasing the number of exposures in the hope of getting something useful.
