J. 106 154 1993 1993AJ....106..154F Clusters, globular Photometry, ultraviolet Stars, variable A set of high resolution images of the core of the Galactic Globular Cluster M15 (NGC 7078) were obtained for the first time with the Faint Object Camera on Hubble Space Telescope through the f/48-F140W, f/48-F220W and f/96-F342W ultraviolet filters. Out of these, 19 are variables discovered from the rms frame-to-frame scatter of the F220W images, 14 of which are probably RR Lyrae.
