ON CORRELATION BETWEEN SUPERWEAK RADIATION READINGS AND COSMOPHYSICAL FACTORS E.S. Gorshkov, V.V.

In order to obtain direct evidence of the influence, we used a supersensitive sensor for superweak radiation ( SSR) in the longitudinal study during the 46th Russian Antarctic Expedition at the Antarctic station Vostok Apr 20 - Dec 21, 2001. The output variable, which is a function of internal resistance of SSR forming elements, was registered [1,2]. The reason to choose the sensor was its successful application for the intervals including instants of the Moon and Sun meridian and horizon transits. These astronomic phenomena, in certain cases, provoked substantial changes in its conductivity. In our study, the meridian-oriented sensor was placed inside a customized metal screen covered with a heating cable and foam enclosure for temperature stabilization. The thermometer was positioned so that its head was 2-3 cm away from the sensor. The SSR output signal was being recorded to PC (using DIGISCOP software) via multi-meter with a sampling period of 5 minutes. Temperature and sensor’s readings correlated at -0.7. To completely eliminate the influence of temperature on the analyzed data, we used new information-bearing characteristics of SSR, which were conventionally named density (absolute deviation of current multi-meter readings from the model curve - dDB) and reliability (number of intersections with the curve during the day - f). Here the model curve was defined on the basis of the most appropriate description of the linear relationship between two parameters within each current 5-day interval: Dbmod = A - B*T, where T is current temperature, Dbmod - prototype curve values, A and В - coefficients. Estimate values of dDB and / averaged over 9 spots were used for studying the correlations of their fluctuations with CPF variations. The obtained results bring the following facts to our attention: The oscillatory nature of dDB and / fluctuations manifested itself clearly with the period of appr. 18-21 days (see Fig. 1). For both indices, the amplitude of oscillation is ±30-40% from the average values. The relative changes of dDB and/ are opposing (r = -0.69). Changes of f are retarded in phase for 2 days from changes of dDB (r = -0.71 at the inversed juxtaposition of curves). *P h y sics o f A uroral P h en om en a ”, Proc.
