We present CCD photometric observations of the slow irregular type variableKU Her. We have also used observations from the ASAS Database and the AAVSOInternational Database. The V-band observations span eight years from August of2002 to September of 2010. The length and density of the data enable us to lookfor variations on time scales ranging from days to years. The V-bandobservations of KU Her are analysed to derive periodicity. This analysis was anapproach to find the fundamental periods of the variability of KU Her. Analysisof the KU Her light variation indicates a complex combination of differentperiods. Five main and three harmonic periods are identified. In addition tothe period analysis, we present the colour variations of the star.
