Spatial distribution of likely members of the stellar association surrounding UBC 103 out to 40′ from its nominal centre. High-probability members in the space of proper motions found by Clusterix 2.0 have been pruned by the parallax and position in the CMD (only stars with 10 ≤ G ≤ 16 are included). The red crosses mark the nominal position of UBC 103 (in the centre of the search area) and the position of NGC 6883 found in Appendix A. We note the lack of members to the west, most likely due to intervening dark clouds causing heavy extinction.
