Astronomical outreach activities for the general public who are unfamiliar to astronomy is a challenging task. It requires creative thinking to solve the problem. The amateur astronomical clubs in a number of cities in Indonesia routinely schedule observations at public parks. The interaction between these clubs and formal education institutions is established by face to face interaction and assisted by social media. The physics teachers who took astronomy courses in university are potential resources to enlarge the outreach scope by creating astronomical clubs as an extracurricular activity. Recent progressive trends in astronomy dissemination for the disabled are also a great opportunity to assist the disabled in experiencing hands-on activities based on formal and informal education.

In the solar atmosphere, below the region of temperature minimum, temperature decreases with height and above it, temperature increases with height. Therefore the inference of temperature minimum is a basis of the study about the solar atmosphere and heating problem. The temperature of the temperature minimum region can be inferred from acoustic cutoff frequency. According to a recent study the acoustic cutoff frequency is related to the peak frequency of the power spectrum the chromospheric three-minute velocity oscillations. Using this relationship, we infer the temperature of temperature minimum. The three minute velocity oscillation and its power spectrum are obtained for a pore observed with the Fast Imaging Solar Spectrograph (FISS) $H{\alpha}$ band. We present the inferred temperature and compare it with the temperature of Maltby model. We also investigate the effect of the inclination of magnetic field on the temperature minimum.

In this article I review the past and current status of solar astronomy in Korea and present some future prospects. Along with a brief historical account on the introduction of modern astronomy to Korea, I describe in detail how solar astronomy in Korea has developed since its birth about 20 years ago. With education of solar astronomers at domestic universities and collaboration with foreign scientists in China, Japan and the U. S., there has been a rapid growth of solar physics in Korea in the past decade. For further advance of solar astronomy in Korea, Korean solar astronomers have to build their own observing facilities and develop instrumentation programs. Also it is very important to bring up manpower competent for these projects.

인터넷상에서 관측할 수 있는 36 츠 자동화 망원경이 개발되었다. 이 시스템의 추적 오차는 약 1"/분이고, 지향 정밀도는 적경 방향에서 약 ${\pm}10"$, 적위 방향에서 약 ${\pm}20"$였다. 이것은 계속 개선되어나갈 것이다. 예비관측을 통해 얻은 영상자료를 IRAF를 통해 분석해본 결과 비교적 안정적인 결과를 보여주었다. 이러한 결과는 원격천체관측 교육에 활용할 수 있음을 의미한다.
