4. Conclusions
(a) The light curve of comet 9P/Tempel 1 was constructed and studied for
all observed comet's returns. The values of photometrical parameters
H
0
,
n
,and
H

were determined.
(b) The value of secular fading of comet was calculated.
(c) The comparison of our results with results of studying of comet's pho-
tometrical peculiarities after impact will be able to give information on
the change of cometary activity as a result of artificial impact to comet
nucleus.
