Coverage map\nof all nine channels is shown at\nhttp://mmt.favor2.info/scheduler/761/lvc\n\nEvery channel acquired 10 x 60s exposure images in white light\nbetween 2015-10-22 22:33:24 UT and 2015-10-22 22:42:31 UT,\nfurther observations interrupted due to heavy clouds. The\nfootprints of acquired images are uploaded to GraceDB.\n\nQuick-look analysis did not reveal any transient brighter than\nV~13.5 magnitude in the data.",
