B, V, R, and I band light-curves of Nova Vul 2024. Red dots are from the AAVSO database, binned to half a day to reduce the noise. Blue dots are ZTF g magnitudes shifted to V band by adding a −1 mag offset, while green dots are ZTF r magnitudes shifted to R band by adding a −0.7 mag offset. The earliest three measurements in the V-band panel, covering the rise to maximum, have been imported from CBET 5423. The observing epochs are counted as days passed since optical maximum on 2024 Jul 30.8 UT (HJD = 2460522.3).
