We present CCD UBVI observations obtained in the field of the two previously unstudied dissolving open cluster candidates NGC 7036 and NGC 7772. Our analysis suggests that both the objects are Open Cluster Remnants (OCR). NGC 7036 is an open cluster remnant with a core radius of about 3–4 arcmin. We derive for the first time estimates of its fundamental parameters. We identify 17 likely members that define a group of stars at 1 kpc from the Sun, with a low reddening , and with an age of about 3–4 Gyr. As for NGC 7772, we identify 14 likely members, that define a group of stars with a very low reddening (), are 1.5 Gyr old and are located about 1.5 kpc from the Sun.
Key words: open clusters and associations: individual: NGC 7036, NGC 7772 - open clusters and associations: general
