0105 Nova Cassiopeiae 1995 - Photometry Update No. 8 (1995/12/06)
0110 ============================================================

0120 Type: NB? Magnitude: 8.4 [mv] - 18 [R] Spectrum: Pec(N)

0130 This nova was discovered by Minoru Yamamoto (Okazaki, Aichi, Japan)
0135 on exposures from Aug. 24, 1995 [IAUC 6213]. Robert Argyle, Royal
0140 Greenwich Observatory, England, has reported the following accurate
0145 position (equinox J2000.0, FK5 reference frame, epoch 1995.69):
0150
0155 R.A. = 01h 05m 05s.353 Decl. = +54d 00' 40".12 [IAUC 6233]
0160 +/- 0s.004 +/- 0".07
0165
0170 This position is based on 10 observations with the Carlsberg
0175 Automatic Meridian Circle on La Palma by C. Fabricius and M. Vallejo.
0180 The corresponding position for equinox B1950.0 is RA = 01h 02m 07s,
0185 Decl. = +53d 44'.6.
0195
0200 Spectrograms by O. Ohshima et al. (Bisei Astronomical Observatory,
0205 Okayama, Japan), T. Iijima and L. Rosino (Asiago Astrophysical Obser-
0210 vatory, Italy), and M. Della Valle (University of Padova, Italy) and
0215 W. Marchiotto and G. Lercher (University of Innsbruck, Austria) con-
0220 firm that this object is a nova. The spectra showed a blue continuum
0225 and narrow emission lines from H I (H-alpha, H-beta) and Fe II with
0230 P-Cygni-type absorption profiles. The widths of the H I lines indi-
0235 cated slow expansion velocities of a few hundred km/s [IAUC 6215].
0240 According to U. Munari et al. the velocities later slowed down to
0245 less than 100 km/s [IAUC 6259].
0250
0255 There have been discussions on VSNET concerning the classification
0260 of Nova Cas 1995, whether it is a classical or a symbiotic nova.
0265 nova. According to the Italian astronomer Ulisse Munari (Asiago
0270 Observatory, Padua) it is of the latter type. His conclusion is based
0275 on the nova's photometric and spectroscopic behaviour until early
0280 November, 1995. On the other hand, the German nova researcher Hilmar
0285 Duerbeck (University of Muenster) classifies it as a slow classical
0290 nova on its pre-maximum phase.

3240 The V-magnitudes were obtained from Mean UBV Catalogue [ref. MUBV],
3250 measurements by Skiff [SK] (see below), Hipparcos Input Catalogue
3260 [HIC], Carlsberg Meridian Catalogue [CMC], and measurements by
3270 Goranskij and Shugarov [SG] (see below). These magnitudes should be
3280 accurate to within 0.01-0.03 magnitudes for all references except
3290 CMC, where the accuracy is around 0.05 mag. Positions and spectral
3300 types were taken from HIC, CMC. PPM Star Catalogue, and Guide Star
3310 catalogue (GSC). Star numbers are from SAO Star Catalog (SAO), Henry
3320 Draper Catalogue (HD), Bonner Durchmusterung (BD), and GSC. The
3330 comparison star identifications are from The Astronomer Electronic
3340 Circular No. 1021 (letters) and NAS.VSS (numbers). The AAVSO numbers
3350 are magnitudes to the nearest 0.1 mag. without the decimal point.
3360 These magnitudes are used on the revised AAVSO (b) scale chart, that
3370 accompanied AAVSO Alert No. 214.

3500 The following message from Brian Skiff (Lowell Observatory, AZ, USA)
3510 to VSNET on 1995 Oct 5 UT [vsnet 240] contains his final photometry
3520 (V, b-y) of nearby comparison stars. It supersedes his earlier
3530 reports from Sep 11 and 12.

3545 >Nova Cas observers,
3550 > I now have reduced a third night of observations for stars in
3555 >the field of Nova Cas 1995. I have added a fainter star (also
3560 >observed by Goranskij and Shugarov), and also three mag. 8.5-9
3565 >stars requested by Kato-san and Patrick Schmeer. The results are
3570 >summarized below. (Thanks to Bjorn for noting the error that
3575 >HD 7178 is TA "D", not "C".)
3580 > The comparison with the stars in common with Goranskij and
3585 >Shugarov is very good, in that our V magnitudes match to within 0.01
3590 >or 0.02 mag. It is very helpful to have their U-B colors as well.
3595 >The stars GSC 3668-1745 and BD+53 215 both appear to be slightly
3600 >reddened M giants; GSC 3668-1121 appears to be a reddened mid-B
3605 >star. My three observations of the latter suggest possible
3610 >variability, or perhaps my most recent V measurement is in error.
3615 > Note again that the observation of the nova is not strictly on
3620 >the standard system because of the mismatch of the emission-line
3625 >spectrum to that of ordinary standard stars.
3630 > I think we're done with this one, so I plan no additional work
3635 >on this field. Sorry for taking so long to get to this, but the

4400 T. Kato reported on 1995 September 24 [vsnet-obs 1216] that S. Masuda
4405 (Ouda Station, Japan) has obtained the following preliminary magnitude
4410 for the GSC 9.0 star, located just east of HD 6250 = SAO 21974
4420 (V = 6.84): V = 9.47. This is star no. 3 in the list of Goranskij and
4430 Shugarov.

4870 Compiler's note: Two stars were labelled as no. 2 on the ascii chart
4880 in their original report. The star located SW of the nova (near
4890 lower right corner) is apparently star no. 3.
4900
4910 Star no. 4 from the above list by Goranskij and Shugarov (revised
4920 magnitudes V=9.599; B=9.715; W=9.361; R=9.452) was a comparison star
4930 for the WBVR-measurements of Nova Cas 1995 by Goranskij, Karitskaya
4940 and Kusakin.

5520 Images of Nova Cassiopeiae 1995 are available from the ftp address
5530 of VSNET, and the URL address of "The Astronomer" group. The

6000 +++++ Electronic charts +++++
6010
6020 Finder charts are available by the anonymous ftp at VSNET at location
6030 ftp.kusastro.kyoto-u.ac.jp in directory /pub/vsnet/Novae/nova_cas95.
6040 The files are ncas95c1.gif and ncas95c2.gif. The second file contains
6050 the V-mag. sequence by B. Skiff.
6060
6070 Preliminary AAVSO (b) and (d) charts in file formats GIF, PostScript
6080 TIFF, may be obtained from the AAVSO ftp site at ftp.aavso.org
6090 (198.116.78.2), in /pub/alert213. Please note that these charts uses
6100 magnitudes of nearby comparison stars from Guide Star Catalogue. It
6110 should be noted that the GSC magnitudes may be in error by 0.5 magni-
6120 tudes or more.
6130
6140 A revised version of the AAVSO (b) chart is, however, available at
6150 AAVSO's ftp site in /pub/alert214. This chart contains V-magnitudes
6160 (rounded to 0.1 mag.) from HIC and B. Skiff's measurements. The chart
6170 files are rather large as the charts have been rescanned in order to
6180 obtain better resolution and clarity. One may also contact AAVSO on
6190 World Wide Web at their URL address http://vsnet.aavso.org.

6500 +++++ Light curves +++++
6510
6520 A light curve for Nova Cas 1995 based on individual observations sent
6530 to AAVSO until early October, 1995 are found at AAVSO's ftp site in
6540 directory /pub/alert214.
6550
6560 Based on 937 estimates from The Astronomer/BAA database, Guy Hurst,
6570 editor of The Astronomer magazine, has prepared a revised light curve
6580 for this nova. It was updated on 1995 November 27 and is available at
6590 the following URL address:
6600 http://vsnet.demon.co.uk/astronomer/images/ncas95_lightcurve.gif
6610
6620 Stig Linander has prepared a weighted light curve for Nova Cas 1995.
6630 The following "weighting" algorithm has been used:
6640
6650 The time axis is divided into intervals of 0.1 days. For each interval
6660 For each interval:
6670 If there is at least one observation in "this" interval:
6680 Set a dot, calculated from observations in "this" interval and
6690 the neighbouring intervals.
6700 Observations in "this" interval are weighted by a factor of 1,
6710 observations "this +/- 0.1 day" are weighted by a factor of 5/8,
6720 observations "this +/- 0.2 day" are weighted by a factor of 3/8,
6730 observations "this +/- 0.3 day" are weighted by a factor of 2/8,
6740 observations "this +/- 0.4 day" are weighted by a factor of 1/8.
6750
6760 If there are three or more contiguous intervals without observations,
6770 the dots are connected by thin lines (3 * 0.1 day ~ 8 hours),
6780 otherwise by "thick" lines.
6790
6800 This is a somewhat empirical algorithm and was the result of some
6810 experimentation in January 1994 to get a "nice-looking" light curve
6820 for Nova Cas 1993.
6830
6840 This light curve can be obtained by anonymous ftp at VSOLJ's site at
6850 ftp.kusastro.kyoto-u.ac.jp in directory /pub/vsnet/Novae/nova_cas95,
6860 or at medusa.uio.no in directory /pub/bgranslo/variable/n1995cas.
