Abstract

We provide a detailed description of the installation and operation of a remote spectroscopic meteor observation system at Unjangsan optical astronomy observatory. Three light-sensitive charge-coupled device cameras were installed, and two cameras had a diffraction grating attached to the front of the lens. Station employ sensitive "Watec-902H2" cameras in combination with f/1.2 lenses were installed in November 2019. Diffraction gratings for spectral observations were used at 500 l/mm. Observations were conducted from November 2019 to June 2020. We employed the SonotaCo UFO software suite for meteor detection. Subsequently, meteor spectra were analyzed using field-tested RSpec software. To analyze the observation images, astronomical calibration and photometric calibration were performed, and the chemical elements of the meteor were determined. The study results are presented along with the system setup installation and operation experience. Brief information regarding the origin of the meteor was also provided based on the results.

운장산 천문대에 있는 원격 유성 분광 관측 시스템의 설치 및 운영에 대해 자세히 설명한다. 총 3대의 고감도 CCD 카메라가 설치되었으며 2대의 CCD 카메라에는 렌즈 전면에 회절 격자를 부착하였다. 시스템은 2019년 11월에 설치되었고, f/1.2 렌즈와 결합된 고감도의 "Watec-902H2" 카메라가 사용되었다. 스펙트럼 관찰을 위한 회절 격자는 500 l/mm이 사용되었다. 관측은 2019년 11월부터 2020년 6월까지 진행되었다. 유성 탐지 및 후속 분석을 위해 SonotaCo UFO 소프트웨어 제품군을 사용했으며, 유성 스펙트럼을 분석하기 위해서는 RSpec 소프트웨어를 사용하였다. 관측영상을 활용하기 위해 Astronomical Calibration과 Photometric Calibration을 수행하였고, 최종적으로 유성의 화학 성분을 분석하였다. 우리는 유성 분광 관측 시스템의 설치와 설정/운영 경험을 설명하고 첫 번째 관측 결과를 제시한다. 또한 결과를 통해 유성의 기원에 대한 간략한 정보를 제공하고자 한다.
