The source is located near the east tail of the CrA molecular cloud.
Wang  has estimated the total gas column density in the cloud at this
position to be about 5 X 1020 cm-2. This strongly suggests that
the source cannot be background to the cloud.
The R CrA molecular cloud is located at 130 pc ; we take this as the upper
limit to the distance.
