Using the Fermi-LAT data taken from UT 2019-09-14 (the nova discovery date) to 2019-09-18 05:52:02, we detected an uncatalogued gamma-ray source at the position of V1707 Sco (aka PNV J17370958-3510211; ATel #13112) with TS = 36 (equivalent to a 6-sigma significance). Assuming a simple power-law spectral model, the best-fit photon index is 2.0 +/- 0.2 with an inferred flux of (2.3 +/- 1.0) x 10^-7 photons/cm^2/s in 0.1-300 GeV. Follow-up observations are strongly encouraged in all bands.
