We present preliminary results of a memership study conducted in the region LDN 1588 located in the λ Ori Star Forming Region (LOSFR). LDN 1588 is particularly important due to it is located on a dust ring formed by material associated to a possible supernova event occurred 1 Myr ago. The study is based on VRI photometry obtained with the instrument OSMOS coupled to the 2.4 m telescope of the MDM Observatory. Based on photometric criteria, we identified 999 photometric members and 1585 possible photometric members of
