[vsnet-campaign-nova 344] V1548 Aql = Nova Aql 2001
> V 1548 Aql = N Aql 2001 is very bright (tonight 13.2 mag - according to
> MEDUZA database). You can find combined vizual+CCD light curve at

See the following portion of IBVS 5100:
Long premaximum halts were also observed
in historical novae, HR Del and possibly in DO Aql. The almost
identical appearance of premaximum halts and sharp maxima suggest
that the common mechanism is responsible for producing such, still
poorly understood, features in slow novae. Both V723 Cas and HR Del
showed oscillations after the main peak (as is also seen in the lower
panel of Figure 1). If similar phenomenon occurs in Nova Aql 2001,
the expected time of the second maximum is around JD 2452080--2452090
(late June, 2001), but the expected dates should be treated as
approximate since the early stage of Nova Aql 2001 was not very well
sampled. The cause of such nova oscillations still being poorly
understood, intensive observations around this period would be
encouraged.
