A total of 10,317 hours of the KMTNet telescope time were allocated for the predefined science programs, and 7,765 hours have been used for science exposures in Chile, Australia and South Africa last year. The success rate of science observation has increased from 70.7% to 75.3%, and the system operation rate has also increased from 97.6% to 99.6%. There were many improvements in mechanical parts of the dome structure and telescope system, and newly installed filter driers of the CCD camera increased the stability of the system by preventing contamination of oil in the gas line in advance. In order to prepare for the time domain astronomy and multi messenger astronomy era, a pilot program was designed and is now being tested. It targets for fast follow-up observations of optical transient events, however it runs during twilight times only so it does not interrupt any granted science program. A total of 32 SCI papers were published using the system in 2018 and it is a good indication of the high science performance of KMTNet. The selection process of the next observation programs starting from October 2020 and its timeline will be discussed in this meeting.

한국천문연구원에서는 2도${\times}$2도 시야의 1.6m 광시야 망원경과 $18k{\times}18k$ 모자이크 CCD 카메라로 이루어진 관측시스템을 남반구천문대 3곳에 설치하여 24시간 모니터링 관측이 가능한 Korea Microlensing Telescope Network(KMTNet)을 구축하고 있다. 망원경 1,2,3호기는 각각 칠레 CTIO, 남아공 SAAO, 호주 SSO 관측소에 2014년말 까지 성공적으로 설치 완료하였으며, 2015년 2월 현재 칠레와 남아공에는 연구용 18k CCD 카메라, 호주에는 시험관측용 4k CCD 카메라를 부착하여 시험관측을 수행중이다. 시험관측을 통해 KMTNet 시스템에서 가장 중요한 부분인 광시야 광학계가 요구사양을 만족함을 확인하였고, 과학연구 수행에 어려움이 없을 것으로 예상한다. 우리는 시험관측을 통해 얻어진 각각의 시스템 성능을 검토하고, 관측 후 파일전송, 전처리 및 자료 배포와 더불어 안정적인 측광성능 유지를 위한 시스템 운영 및 향후 계획에 대하여 발표한다.

BITSE is a balloon mission, which is a solar coronagraph to measure speed and temperature of the solar wind using 4 different wavelength filters and an pixelated polarization camera. KASI and NASA jointly designed, developed, and tested the solar coronagraph. Mainly KASI developed an imaging system and a control system, and NASA developed an optical system and mechanical structures. We mount the BITSE on Wallops Arc-Second Pointer (WASP) of Wallops Flight Facility, and launch it with a 39 mcf balloon of Columbia Scientific Ballon Facility. We will introduce the overall system of the BITSE.
