摘要：

During the nights of 18-22 March 1998, the Palomar 200 " adaptive optics (AO) breathed its first breathe of life, closing lock on a natural guide star for the first time. We present telescope results obtained during the initial closed-loop tip/tilt tests of the AO system at the 5m Hale Telescope on Palomar Mountain. Furthermore, we report on the first light results of the Palomar High Angular Resolution Observer (PHARO). Early tip/tilt correction results demonstrate a factor of similar to 1.3 improvement in peak infrared irradiance for several second exposures. The facility AO and PHARO systems are scheduled for a series of engineering runs throughout 1998. Initial closure of the 241 actuator high order natural guide star (NGS) adaptive loop is expected this summer.
