V975 Oph: likely bright SU UMa star

Using ATLAS forced photometry (Tonry et al. 2018; Shingles et al. 2021), I found that this object is most likely an SU UMa star. The most recent superoutburst occurred in 2022 Sep. (14.4 mag). Superhumps were likely present in the spread of ATLAS measurements. The supercycle was likely around 270 d (measurement hindered by solar conjunctions).
