BVRI photometry was obtained on 2026-06-20.125 UT using a 0.4-m Dall-Kirkham telescope equipped with a Moravian G4 full-frame CCD camera at Novezzina Observatory, Italy. The measured magnitudes are: B = 17.56 ± 0.10 V = 17.20 ± 0.10 R = 17.10 ± 0.20 I = 17.20 ± 0.10 A possible quiescent counterpart was identified in the Gaia DR3 catalogue as Gaia DR3 2071985961279196032, with G = 19.66 mag. The observed outburst amplitude is therefore approximately Δmag ≈ 2.9 mag. The observed colours (B−V ≈ 0.36, V−R ≈ 0.10, R−I ≈ −0.10) and the moderate outburst amplitude are consistent with a cataclysmic variable in outburst. Inspection of the archival ZTF r-band light curve shows the source predominantly near a quiescent level of r ≈ 18.6 mag, with no clear evidence of previous large-amplitude outbursts in the available data. While the present observations are compatible with a dwarf nova interpretation, possibly of the U Gem or SU UMa subtype, additional spectroscopic observations and time-resolved photometry are required to establish a reliable classification.
