We present CCD photometric observations of the slow irregular type variable
KU Her. We have also used observations from the ASAS Database and the AAVSO
International Database. The V-band observations span eight years from August of
2002 to September of 2010. The length and density of the data enable us to look
for variations on time scales ranging from days to years. The V-band
observations of KU Her are analysed to derive periodicity. This analysis was an
approach to find the fundamental periods of the variability of KU Her. Analysis
of the KU Her light variation indicates a complex combination of different
periods. Five main and three harmonic periods are identified. In addition to
the period analysis, we present the colour variations of the star.Comment: 14 pages, 4 figure
