		| Abstract: | 
		We present results of photometric observations of the young eclipsing binary KH15D obtained during three observing seasons of 2002–2005. A comparison of our data with data from the literature reveals the existence of the long-term photometrical brightness trend: during 4.5 years a system brightness in the Ic-band decreased by about one stellar magnitude. |
