It is shown that the shape of histograms of independent measurements d
epends on the time. The similar histograms are observed for 2-3 hours
and further they appear in 24, 48, 72 and 96 hours. The possible artif
acts were analysed and excluded. The obtained dependence of the simila
rity of histogram shape on the time evidences that shape of histograms
: 1) is not occasional, 2) is induced by cosmophysical factors, 3) is
changed with <<the time life>> about an hour and 4) depends on the Ear
th rotation.
