GMG 2.4m Telescope (Yunnan Observatories)

The GMG 2.4-m telescope is located at the Lijiang station of Yunnan Observatories, Chinese Academy of Sciences (longitude = 100°01’51” E, latitude = 26°42’32” N, altitude = 3193 m). It is similar to the Liverpool and Nordic telescopes.

🔭 The Telescope

The camera Yunnan Faint Object Spectrograph and Camera (YFOSC) is mounted on the telescope, equipped with a back-illuminated 2048×4096 E2V42-90 CCD.
The field of view is approximately 10× 10 arcmin.

The general photometric and low/middle-resolution spectral observations can be performed by this telescope. Using YFOSC, the limiting magnitude varies from 22 to 24 mag depending on the exposure time and the seeing. For low/middle spectral observation, we expect a magnitude limit between 16-17 mag depending on features in the spectrum. Also, YFOSC can also perform high-resolution observations (R=30000-50000), but this requires some time for preparation.

Scientific targets include the characterization of gamma-ray burst and gravitational wave counterparts, X-ray binaries, flaring AGN, and other transients.
