METHODS. We used our own visual spectroscopic and UBV photometric data of a 30' x 30' region centered at R.A. = 8h44m47.2s, Decl = - 45d58m55.5s. This information enabled us to estimate the spectral classification and distance of all stars present in the region. The proper motion was analyzed with data of the UCAC5 catalog and was used to identify the members of this association. We added JHK data from 2MASS an","authors_text":"Guillermo L. Bosch, Mariela A.
