RCW 14 appears to be a visible part of the [JKK96] B
giant molecular cloud and is part of the GS234-02 supershell. The main ionising star is the O8 V star HD 57236
Avedisova lists 3 additional B-class ionising stars and places RCW 14 in the star formation region SFR 235.54-4.06
along with the star cluster NGC 2367
. The RCW catalog also associates RCW 14 with NGC 2367.
Kharchenko gives a distance of 2004 parsecs and an age of 10.2 million years for NGC 2367.
The exciting star is the O8 V star HD 57236. [1

Bica, et.al. find a 55 solar mass star cluster in this direction ([BBD2004] Cluster 3
) at a distance of 3930 +/- 350 pc. They conclude that it is a background object lying behind the nebula. The same paper adds that RCW 14 appears to be the nucleus of the larger nebula Brand 16. [3
