The Korea Astronomy and Space Science Institute announced on the 9th that it had successfully completed ground-based observations of the total solar eclipse phenomenon that took place across North America.
The Astronomical Research Institute dispatched two teams of observers to observe the total solar eclipse, which lasted 2 hours and 40 minutes from 12:18 to 2:58 p.m. on the 8th (local time) in Lampasas, Texas, USA. It was announced that ground observations were conducted for core research on the Coronagraph for the International Space Station (CODEX), which was jointly developed with the National Space Agency (NASA). The total eclipse period during which the sun was completely obscured was 4 minutes and 26 seconds.
Cho Kyeong-seok, a senior researcher at the Astronomy Research Institute, said, “Despite the cloudy weather, the Astronomy Research Institute-NASA team secured both polarized and non-polarized images through four filters that can determine the temperature and speed of the corona.” He added, “Through future data analysis, we can determine the low corona rate.” “We plan to analyze in detail the polarization characteristics and the effects of polarization in the Earth’s atmosphere,” he said. The observation results will be used as corona research data along with the observation results of CODEX, which will be installed on the International Space Station in September.

The horizontal axis direction is the slit (a small gap that allows only part of the wave or light to pass), and the vertical axis direction is the spectral direction. The four bright lines, inclined about 60 degrees, are the chromospheric spectral spectrum visible at the Sun’s edge during a total solar eclipse. The two bright small dots within the line at the upper left are chromospheric lines emanating from the prominence. The two bright lines running horizontally are the emission lines of corona ions.
