RS Oph in 1945. Like the 1907 eruption, the peak of the 1945 eruption was missed inside the solar gap when RS Oph was behind the Sun. Like in 1907, the post-eruption dip is easily seen and diagnostic of the missing eruption. Unlike the 1907 eruption, the AAVSO V-band light curve (circles) displays a fading tail of the nova eruption. Indeed, at V = 9.6 mag just after the solar gap, RS Oph is brighter than at any other time in its observed history outside of eruption. The small circles are for individual magnitude estimates and the large circles are for 3-day averages (for days 202–333) with typically 4.4 mag for each point.
