Comet Holmes was discovered by Edwin Holmes on Nov. 6, 1892 during a large outburst. On Jan. 16, 1893 a second outburst occurred. During the following appearances in 1899 and 1906 the comet was faint (only 13m and 15m, respectively). The comet was last observed on Dec. 7, 1906. After the 1906 apparition the comet was lost. B. G. Marsden found that a close Jupiter passage on Dec. 9, 1908 changed the comet's orbit considerably. He predicted the next comet's appearance in 1964. The comet was recovered on July 16, 1964 using Marsden's prediction. The comet has been observed at every return since 1964. During the appearance in 2007 the comet had shown a unique outburst of amplitude about 15m on Oct. 24, 2007. Authors constructed and studied the light curve of integrated visual brightness of comet 17P/Holmes during appearance in 2007. The values of photometrical parameters H0, n, and H10 were computed for all observed comet's appearances. The secular variation of cometary brightness was studied. The quasi-periodicity of the cometary activity is discussed. The total light curve and light curve of outbursts were compared with variation of solar activity indexes. The results of our CCD observations of comet Holmes are discussed also. The results obtained by authors are important for development of outburst mechanism of this comet.
