From 27th to 28th March 2015the Acceptance Conference of Optical and Near-infrared Solar Eruption Tracer (Onset) developed by NIAOT was held in Kunming city of Yunnan provinceThe Acceptance Conference was organized by Nanjing UniversityThe Committee of acceptance confirmed that all the design requirements were achieved and first-class solar image at four wavelength band was obtained in the worldOnset was propose by Nanjing Universitydeveloped by NIAOT and installed near Fuxian Lake in Yunnan Province

Solar observation with high space and time resolution can be achieved at four wavelength band (6562.81Å10830 Å3600 Å and 4250 Åthrough OnsetOnset can simultaneously obtain full disk and partial disk10')solar image at four wavelength band with resolution better than 1'。

According to different observation modedata can be obtained (at 6562.81Å line centerblue and red wings10830Å line center, blue and red wings)First filter at 10830Å is developed in China meanwhile full disk and partial disk image at 10830Å can be obtained

In additionOnset has unique ability for solar image at 3600Å in the worldONSET is expected to obtain valuable data and contribute significantly to the development of solar physics and space weather.
