V373 Scuti was a nova which appeared in 1975 in the southern constellation of Scutum.[3] It was announced on June 15, 1975 by Paul Wild at the Zimmerwald Observatory, Switzerland.[7] At the time the magnitude was about 7.9.[8] The peak magnitude of 7.1 occurred a month earlier on May 11.[2]
The light curve of this nova declined as a typical power law following the peak, but showed significant jittery behavior.[10] After about 40–50 days emission lines began to appear in the spectrum, which allowed measurement of the mean expansion velocity as Script error: No such module "val"..[8] The large amplitude flickering as well as other indicators suggest a magnetic influence, making this a candidate intermediate polar system. A luminosity modulation of 258.3 seconds is most likely due to rotation of the white dwarf.[5] The system has an orbital period of Script error: No such module "convert".,[3] and the light curve suggests a high orbital inclination.[5]
