Some of us still remember the years 2020 and 2021, when we had the opportunity to observe several bright novae in the northern sky one after another. In order of their discovery dates: V1361 Cyg, V1112 Per, V1405 Cas, V1674 Her, V606 Vul, with the recurrent nova RS Oph bringing this remarkable sequence to a climax.
In the summer of 2026, four readily observable novae appeared within a single season of the year. Their basic properties are summarised in Table 1. Figure 1 illustrates the diversity of their light curves. The traditional way of classifying novae according to the MMRD (Maximum Magnitude Rate of Decline) is illustrated by marking the T2 times — that is, the time required for the nova to fade by 2 magnitudes from maximum brightness. The limitations of this approach are evident in V1452 Tau, which reached maximum brightness three, or perhaps even four, times.
