Description of 2MASS-GC01

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.
