Аnnotation: The influence of heliogeophysical activity on the COVID-19 epidemic, caused by coronavirus SARS-CoV-2, in Moscow is considered. The analysis of official data of the pandemic in Moscow showed that heliogeophysical activity has an impact on the occurrence and course of an infectious disease. The pandemic occurred in winter, when the solar activity was minimal and the level of ultraviolet radiation was the lowest. The study showed a significant relationship between the infectious process and geomagnetic activity: periods of outbreaks of infections and deaths correlated with periods of decreasing geomagnetic activity lasting several months. The impact of magneto-spheric storms and substorms on people during the pandemic is also considered. It is shown that during the minimum of solar activity, periods of geomagnetic disturbances lasting from one to several days additionally and statistically significantly increase both the number of infections and the number of deaths. The presented evidence indicating that solar activity has a direct or indirect effect on the occurrence of outbreaks of infectious diseases is important to understanding the processes of the occurrence and development of epidemics.
