Map showing all the likely members of the new cluster Alicante 6 and the surrounding association that fits the ZAMS at DM = 12.4 (circles). The two objects marked with squares have dereddened magnitudes incompatible with their spectral types. C81 (O7 V) is more than one magnitude brighter than expected. Its spectrum suggests that we are seeing at least two unresolved stars. C129 (B7 III), on the other hand, cannot be associated with Alicante 6 and is likely to be on the Sagittarius arm.
