Synchronous Changes in Dark Current Fluctuations in Two Separate Photomultipliers in Relation to Earth Rotation

We recorded the fluctuations of the dark current in two photomultipliers located 2000 km from each other in different time zones (in International Institute of Biophysics (Neuss, Germany) and in Moscow State University (Moscow, Russia)). We studied the fluctuations by distribution of their amplitude...

Description
Summary:We recorded the fluctuations of the dark current in two photomultipliers located 2000 km from each other in different time zones (in International Institute of Biophysics (Neuss, Germany) and in Moscow State University (Moscow, Russia)). We studied the fluctuations by distribution of their amplitudes (histograms of data). Comparison of the histograms obtained in both locations revealed the higher probability of the similarity of the histogram shape for the measurements done at the same local time. This observation is in a good agreement with similar correlations we have previously found in different spatially separated processes. These data suggest that some cosmophysical factors affect many fluctuations processes observed on the Earth.
