Abstract

The RR Lyrae variable TT Scuti was studied using photographic photometry. The O-C data show a possible downwards curve, which would indicate a decreasing period, but the results are not conclusive. New linear elements are: JD(max) = 2439384.915 + 0.45293855 E. A limit for the maximum rate of change of the period is -0.03 +/- 0.04 cycles per million years.
