Uncertain identification. Photometry (V= 19.7; V-J= 7.8) is for the red star IPHAS J190740.03+102945.5 (g-r= 2.9; J-K= 2.45; BP-RP= 7.02). The GCVS (version Nov. 2020) and the Downes catalogue identify the nova as the bluer star IPHAS J190739.84+102943.2 (g= 20.2; g-r= 1.0), which is 4" to the SW. This object is also classified as variable in 2021A&A...648A..44M and was also detected as a transient by ZTF (ZTF19abciwnk). The finding chart in 1987SSRv...45....1D does not have enough resolution to solve the two candidates.
The bluer star is likely the true nova.

The ZTF data showed a dwarf nova-like phase in 2019 June-Aug. Time-resolved data on 2018 Aug. 4 showed some degree of flickering. This is most likely the CV.
