 A refined period of 0.3488463(18) and Fourier decomposition components are provided for the RR Lyrae variable USNO-A2.0 1200-07442272, which lies in the field of TY Boo. The star is found to an RRc variable with a hump on the rising branch, and also has very low metallicity, [Fe/H] ZW = -1.5 and [Fe/H] CG = -1.2, typical of the halo population. It is an extreme halo object and probably lies at nearly 6 kpc from the galactic plane.

Simbad object(s): 2MASS J15004755+3509514,
