Abstract
Urgency. The ionosphere remains the main channel used by radar, radio astronomy, radio navigation, communication links, and remote radio sounding. The parameters of this channel significantly depend on the influence of high-energy sources that take place in the Earth–atmosphere–ionosphere–magnetosphere (EAIM) system. One of these sources is a solar eclipse (SE). An urgent issue is to study the features of the ionospheric response to the SE action, which takes place near the moments of sunset.
The aim of this paper is to describe the results of studying the temporal variations in the total electron content (TEC) in the ionosphere caused by the SE near the evening terminator.
Methods and Methodology. The results of measuring the parameters of the radio signals from GPS Global Navigation Satellite System (GNSS) at the Novosibirsk station (NVSK) for six satellites (G04, G07, G09, G16, G26, and G27) were used as the initial data. The TEC estimation error did not exceed 1%.
Results. For the first time, the TEC response to a solar eclipse that occurred prior to and during the passage of the evening terminator was studied using GNSS technologies. It has been established that an SE triggers physical and chemical, and dynamic processes in the EAIM system, which ensure the continuation of the ionospheric response after the end of an eclipse and after sunset on the Earthʼs surface. The duration of the response reached 120–180 min. At the maximum magnitude of the SE, the TEC deficit did not exceed 5 TECU or 33–36%. The magnitude of the deficit most of the time tracked the decrease in the magnitude of the SE and the solar disk coverage area. There are grounds to believe that there was a synergistic interaction between the following two sources, the solar eclipse and the terminator.
Conclusions. The main features of ionospheric effects from the solar eclipse during the period of the evening terminator have been established.
