ATel #18008; Spectroscopic Observation of PNV J19450648+1822422: Likely a Classical Nova? From ATel; https://www.astronomerstelegram.org/?read=18008 PNV J19450648+1822422 was originally discovered by the NMW-TexasTech survey. Its position coincides with a known eclipsing binary candidate in Gaia, with an orbital period of 9.9011 d. Thus, time-resolved observations may reveal eclipses during its decline as the photosphere recedes. http://www.cbat.eps.harvard.edu/unconf/followups/J19450648+1822422.html https://vsx.aavso.org/index.php?view=detail.top&oid=10762522 See also the case of U Sco and its eclipses during the nova eruption; Muraoka et al 2024 https://arxiv.org/abs/2402.06347 Best regards, Yusuke -- ---------------------------------------------- Yusuke TAMPO / 反保 雄介 Postdoc fellow South African Astronomical Observatory / University of Cape Town EMAIL: tampo@kusastro.kyoto-u.ac.jp ALT.
