2MASS-GC02 was discovered by 2MASS telescope operator Joselino Vasquez in his observing logs as a suspected globular cluster, and confirmed by visual inspection of arbitrary 2MASS Atlas images, together with its apparent neighbor, 2MASS-GC01. It is heavily obscured in the visible part of the spectrum by about 18.0 +/- 1.0 magnitudes, and therefore only discovered in the infrared. 2MASS-GC02 was Milky Way Globular Cluster No. 149 to be discovered.
The extinction of light for this cluster is stronger at the shorter wavelength, so that the light of the stars appears reddened even in this false-color IR image; they are seen chiefly in the Ks and H band.
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.
