WDS 20100-2802 BRG 30 : NOTES

discov_num	notes	refcode
BRG 30	Given the relatively small separation (~0.62") and the similar
	brightnesses of the two components in the 2MASS J20100002-2801410
	system, it is likely that they form a physical pair. However, only one
	epoch of imaging exists at this point.	Jnn2012
