The massive star formation region RCW 106 is visible in the direction of the R103 OB association and is embedded in a 100 thousand solar mass 28 pc x 94 pc giant molecular cloud. It is ionised in part by the two obscured infrared star clusters slightly separated from the visible luminosity: IRAS 16132-5039
and IRAS 16177-5018
. IRAS 16177-5018 contains the ultrahot star [RAL2003] IRS 1
, which is probably an O3 I supergiant. IRAS 16132-5039 contains the O9.5 V / B0 V star [RA2004a] IRS 3
Avedisova places RCW 106 in the star formation region SFR 332.87-0.64
with 97 components, including 25 masers.

Analysis of infrared clusters.[1
RCW 106 is a massive star formation region.[2
RCW 106 is embedded in a larger 100 thousand solar mass 28 pc x 94 pc giant molecular cloud.[3
The RCW catalog designates the two brightest regions of this nebula as RCW 106a and RCW 106b but these do not appear to be distinct objects.
