V1494 Aql: In decline phase
In the early January, V1494 Aql = Nova Aql 1999 No. 2, which had continued
fading trend, was reported to be brightening to 7.6mag
And then, it returned to fading phase
After the magnitude reached to 9.2-9.4mag, the object again showed
temporal re-brightening to 8.0mag on February 8
After that, the fading trend became more rapid
P. Schmeer and the other observers reported a sudden brightening
to 8.3mag on March 2.215
followed by the normal decline. On March 14, another brightening (8.8mag)
was reported by B. H. Granslo and P. Schmeer et al.
On March 31, it again became bright (8.4mag) as reported by M. Verdenet
L. Cook also detected
the periodic variation (P=91min) and the amplitude of about 0.04mag
A. Retter reported the main results through 14 nights observations by
R. Novak and L. Cook: there is a very strong signal at 14.86 c/d=1.62 h.
It is near a 1-d alias of the periodicity previously reported to the IAUC.
The full amplitude was slightly increased and was nearly 0.10 mag.
There might be other periodicities, however, to establish their presence,
more data is needed
