In 1992 trial observations began with a prototype telescope designed at NTHU, and after modifications it was shipped to Tenerife in Spain's Canary Islands in June 1993, to be installed and begin operation. Six months later, a second telescope arrived at the Huairou Solar Observing Station in Beijing, and six months after that a third was successfully set up at the Big Bear Solar Observatory in California.
