We report the spectroscopic observation of the transient ZTF22aazdzyj/AT2022qpg in M31 from the SALVATION project (ATel #13952). This transient is the recurrence of the nova M31N 2005-10a (Atel #15545). It was flagged from the ZTF public alert stream by the ANTARES alert-broker. The spectrum was obtained on 2022 August 11 UT with the Kast double spectrograph on the Shane 3-m telescope at Lick Observatory.
