聯合觀測是一種符合經濟效益且能快速蒐集觀測資料的方法。我們提出一套用來進行天文聯合觀測的系統，這個系統包含一個線上平台：Spacelink，與一個實體社群：臺灣天文聯合觀測網(TOP)。透過Spacelink，任何人都可以提出有趣的觀測計畫，吸引志同道合的成員一起參與觀測。這些計畫主題不限於學術科學研究，純粹的天文攝影也都是有趣的題目。透過聯合觀測，成員可以共享觀測資源與觀測成果，並在參與計畫的過程中學習到天文觀測的知識與資料處理的方法。臺灣天文聯合觀測網是屬於台灣在地的天文社群，期望透過互動與交流，促進成員之間的合作，並共享有限的教育資源。天文學術機構、中小學校與天文同好都是我們的合作對象。我們也期許能藉由公民科學參與，啟發並培養台灣民眾對於天文科學的興趣，進而達到教育推廣的目的。

We introduce an online platform Spacelink, and a community TOP for open collaborations in astronomical observation. Spacelink allows members to propose observation ideas in either scientific or astrophotography fields to attract and collaborate with people who have similar interests. Collaborative observations allow members to share observation resources as well as the produced results within the projects. On the other hand, Taiwan astronomical Observation collaboration Platform (TOP) is a community for Taiwanese people, particularly educational organizations, to further exchange and share educational resources with one another while participating in astronomy observations. We aim to promote citizen science to inspire and cultivate the interest of Taiwanese people in the fields of science and technology.
