Changes of HR (beat/min), RR (resp.cycles/min) and DSM (sec) at synchronization of two rhythms - physiological (RR) and psychophysical (DSM) before, during and after stay in Antarctica. The further study of DSM was performed in 2002-2008 to estimate the influence of such astronomic phenomena as new moon (NM), full moon ( FM), solar and lunar eclipses (SE, LE) onto DSM variations. Over 20 sets of registering DSM during 6 to 12 hours were done, covering the astronomic phenomena named above and intervening intervals. In each case (except intervening intervals) the variations of DSM were similar: within 2-2.5 hours it increased to the maximum, exceeding 1.5-1.8 times the level at intervening intervals (at the moment of the Sun, the Earth and the Moon’s collinear positioning), and then decreased within appr. 2-2,5 hours. Fig. 5 illustrates the averaged density of distribution of DSM fluctuations (19 sets), describing NM, FM, SE and LE, with the peak values co-located in one point. Fig. 6 describes it for nadirs of the Sun (12 sets), with the values registered at 1 a.m. co-located in one point. The average values of DSM peaks are: 86,3 sec at FM, 99,5 sec at LE, 85 sec for NM, 90,3 sec for SE and 65 sec for intervening intervals. The distribution pattern for DSM peaks describing NM, FM, SE and LE during the day was defined. According to it, DSM extreme values are located within the interval of 4-6 hours, which clearly agrees with its daily distribution. 169
