Abstract:
    We present near-infrared (NIR) J-, H-, and K-band time series
    observations of the Galactic globular cluster (GGC) M92.

Description:
    The NIR data for M92 were collected using the AZT-24 1.1m telescope
    of the Campo Imperatore (L'Aquila, Italy) observatory, located at an
    altitude of 2150m near the Gran Sasso d'Italia mountain.
