[vsnet-obs 26938] V1494 Aql and Nova Sct 2000 - Mar 15-21 UT



Norwegian Astronomical Society - Variable Star Section

1918+04  V1494 AQUILAE (Nova Aql 1999 No. 2)

Further observations by NAS.VSS observers:

Object    YYMMDD(UT)   Mag  Obs  Instrum.    Observation
AQLV1494  000315.177   8.6  GRL  C203;100x   5-3;6+2;7+3 [1]
AQLV1494  000321.142   9.4  GRL  C203;100x   6-6;7-4;9+4 [1]

Sequence: NAS.VSS, with V magnitudes from the Tycho-1 catalogue
  (http://vsnet.astro.uio.no/~bgranslo/catalogs/V1494_Aql_B.gif).

1828-14  NOVA SCUTI 2000 (HadV46)

This object was discovered by Katsumi Haseda (Aichi, Japan) on
exposures from 2000 Mar. 5.81 UT (mag. 10.6). It was visible on an
earlier image from Feb 6.84 UT (mag. 12.0), but was not detected
on images until 1999 Nov 10.38 UT (mag. limit 13.0-13.5). A
spectrogram by M. Fujii from Mar 16, showed that the object was
a nova, due to a strong H-alpha emission (FWHM = 940 km/s). The
nova is located at R.A. = 18h34m03s.2, Decl. = -14o45'12" (2000.0).
The discovery was formally announced in IAU Circular No. 7382.

I attempted to observe the nova on March 21 but was not able to see
it. The following negative observation was recorded:

Object       YYMMDD(UT)    Mag  Obs  Instrum.    Note
SCTnova2000  000321.161  <11.2  GRL  C203;287x   Seq. Tycho-2

The limiting magnitude is based on the visiblity of the star
TYC-2 5703-0718 (V=11.24, B-V=+0.75). This observation was
affected by light pollution (morning twilight + outdoor lights)
and poor seeing due to low altitude. It was, however, easy to
locate the field.

Observer:
GRL = B. H. Granslo (Fjellhamar, Norway). Instrument: 20.3-cm SCT
  (C203). Nearly clear, both on Mar 14-15 and Mar 20-21.

                                Yours sincerely,
                                Bjorn H. Granslo
