The CCD UBV(RI)KC photometry of the poorly studied open clusters Juchert 9 (Juc 9) and Berkeley 97 (Be 97), which are observed with the 0.84 m telescope at the San Pedro Mártir National Observatory, México has been analyzed. For the likely cluster members, we determined the reddenings, E(B‐V) = 0.82 ± 0.04 (Juc 9) and E(B‐V) = 0.87 ± 0.05 (Be 97), from the early type stars. Our distance moduli/distances for only (B − V) color are (V0‐MV, d[kpc]) = (13.40 ± 0.10, 4.8 ± 0.2 kpc) (Juc 9) and (12.40 ± 0.12, 3.0 ± 0.2 kpc) (Be 97), respectively. The Gaia DR2 distances are d = 4.5 ± 1.2 kpc (Juc 9) and d = 3.1 ± 0.7 kpc (Be 97) from the median parallaxes with σϖ/ϖ < 0.20, which are in good agreement with the photometric distances within the uncertainties. The solar abundance PARSEC isochrones give us the intermediate ages, 30 ± 10 Myr for Juc 9 and 100 ± 30 Myr for Be 97.

The open clusters NGC 2323 and NGC 2539 have been analysed using CCD U BV(RI) KC photometric data, observed at the San Pedro Mártir Observatory. Cluster memberships have been determined with the proper motion and parallax measures from the GaiaDR2 astrometric data release. Photometric metal and heavy element abundances have been obtained as ([M/H], Z) = (−0.10, 0.012) (NGC 2323) and (−0.31, 0.007) (NGC 2539), from the δ(U-B) technique in the two colour diagrams, which are used to select the appropriate PARSEC isochrones. The estimated reddening of NGC 2323 is E(B-V)=0.23±0.04 using 11 early type stars. For NGC 2539, we find E(B-V)= 0.02±0.06. For (B-V) colour, distance moduli and distances for NGC 2323 and NGC 2539 are derived as (V 0 -M V , d (pc)) = (10.00±0.10, 1000±50) and (V 0 -M V , d (pc)) = (10.00±0.04, 1000±20), respectively. The median GaiaDR2 distance d=1000±140 pc ( =0.998±0.136 mas) for the likely members of NGC 2323 is in concordance with its four colour photometric distances 910-1000 pc. For NGC 2539, its GaiaDR2 distance d=1330±250 pc ( =0.751±0.139 mas) is close to its four colour photometric distances, 1000 pc. Fitting the PARSEC isochrones to the colour magnitude diagrams (CMDs) gives an old age, 890±110 Myr, for NGC 2539. Whereas NGC 2323 has an intermediate-age, 200±50 Myr. One Red Clump/Red Giant candidate (BD-12 2380) in the CMDs of NGC 2539 has been confirmed as a member in terms of the distances d I =950±50 pc and d V =910±90 pc of V I filters within the uncertainties, as compared to the distance, 1000±20 pc of NGC 2539. This giant's GaiaDR2 distance (d=1200±70 pc) is not close to these photometric distances.
