Discovered in 2000 by R.J. Hurt et.al. in 2MASS IR records.

Globular cluster 2MASS-GC01 was noted by visual inspection of arbitrary images from the 2MASS Atlas data, together with the apparently neighbored globular 2MASS-GC02 at less than 1 degree separation. Effectively obscured in the visible light by an estimated 21.5 +/- 1.0 magnitudes, it could only be discovered in the infrared. It was Milky Way Globular Cluster No. 148 to be discovered.

This high obscuration occurs because of the cluster's low galactic latitude of about 0 deg, and its proximity to the Galactic Center of about 10 deg. The globular cluster is primarily seen only in the H and Ks bands; hence, the rather reddish color for the cluster stars in our false-color IR image.

The image in this page is an infrared photo. It was obtained within the Two Micron All Sky Survey (2MASS) and taken from the 2MASS atlas. Colors represent different IR bands: J band (1.2 micron) is represented blue, H (1.6 micron) green, and Ks light (2.2 micron) red.
