V1178 Sco : Nova Sco 2001
K. Haseda discovered and reported a possible nova of 10th mag
on June 20. The object has already been bright at least since
May 13 according to his previous observations
(vsnet-campaign-nova 350).
K. Takamizawa's observations revealed the eruption began between
April 26 and May 12
(vsnet-campaign-nova 351).
W. Liller reported short-term oscillations in June 22, 24, 26, and 27
observations
(vsnet-campaign-nova 360,
368,
371).
On June 24, M. Fujii took a spectrum which provided a firm evidence
that V1178 Cyg is a genuine nova
(vsnet-campaign-nova 366).
The spectrum taken on July 2 showed the weak presence of P Cyg-type
profile both in H-alpha and beta. The Fe II emission series are
characteristic to a Fe II-type nova
(vsnet-campaign-nova 387).
The object faded after its peak. H. Itoh's observation on July 1
indicated a brightening from about 12.0 to 11.3mag
(vsnet-campaign-nova 385).
The object keep the gradual brightening with oscillations during the
early July
(vsnet-campaign-nova 393),
and returned to the fading stage in the mid-July
(vsnet-campaign-nova 402).
