The GALEX (Galaxy Evolution Explorer) Mission has obtained NUV and FUV light curves of the Robotic Optical Transient Search Experiment (ROTSE-I) Catalog RR Lyrae type ab variable star J143753.84+345924.8. A series of GALEX Deep Imaging Survey observations well distributed in phase within the star's 0.564 day period shows an AB 4.5 magnitude variation in FUV (1350-1800Å) and an AB 2.0 magnitude variation in NUV (1800-2800Å), compared with 0.75 magnitude in the ROTSE-I visible band. The large FUV brightness variation makes RR Lyrae stars easy to detect in FUV imagery and the GALEX single-orbit ( 1500s) limiting AB 23 magnitude in both NUV and FUV make the detection of more RR Lyrae stars likely.
GALEX (Galaxy Evolution Explorer) is a NASA Small Explorer, launched in April 2003. We gratefully acknowledge NASA's support for construction, operation, and science analysis for the GALEX mission.
