TNS Astronomical Transient Report No.168720 Discovery certificate for object 2023ps
Remarks: F.Castellani, R.Belligoli, V.Andreoli, C.Marangoni,
OMB extragalactic nova monitoring by ISSP collaboration reports the discovery of a probable nova in M31. The transient designated also PNV J00424623+4117357. New transient was clearly detected on '2023 1 14,7674' UT using 16 x 300s frames (4800s total) obtained by a Moravian G4-9000 KAF unfiltered CCD with the 0.4m f.8 Ritchey-Chrétien telescope from Monte Baldo "A.Gelodi" Astronomic Observatory, località Novezzina, Ferrara di Monte Baldo, Verona, Italy. The discovery magnitude is 19.3±0.5 mag in the CV band (clear visual). Offset 25" Est e 90" Nord from M31 galactic centre. The new transient is close to Globular Cluster M31GC J004246+411737 (1.78"). (AT2023ps)
Spectroscopic Observation of the Dwarf Nova PNV J00215475+5231007
Remarks:V.Andreoli, A.Vagnozzi. Also, weak absorption lines of Hα, Na I, and Mg II are seen. Therefore, my spectrum is consistent with the report on CBAT by V. Andreoli & A. Vagnozzi, confirming their classification as a cataclysmic variable. According to the photometric observations by S. Kiyota, H. Itoh, and the Kyoto U team, this object is likely a WZ Sge-type dwarf nova (vsnet-alert 27305 & 27306).

A new outburst of the symbiotic star V919 Sgr, again 15 yrs past the previous one
ATel #15528; U. Munari (INAF Padova), A. Vagnozzi, A. Maitan, F. Castellani, M. Graziani (ANS Collaboration), P. Ochner, A. Reguitti (Padova Univ.) on 25 Jul 2022; 15:44
V919 Sgr is a bright symbiotic star, of the burning type, which is largely ignored by observers. Its first known outburst in 1991-92 was described by Ivison et al. (1993, A&A 277, 510), with a second one in 2007 reported by Munari et al. (2007, CBET 999). V919 Sgr is currently again in outburst, as also noted by B. Monard in vsnet-alert N. 26878. The three recorded outburst are separated by similar ~15 yrs intervals. (ATel15528)(PDF)

Discovery certificate for object 2022elz
Remarks: Flavio Castellani report the discovery by F.Castellani, R.Belligoli, V.Andreoli of a PNV (Mag.19.5R +-0.2 - USNOB1 catalogue) in the host galaxy M81 at Monte Baldo Observatory, Ferrara di Monte Baldo, Verona, Italy (A99), in the course of Italian Supernovae Search Project using a 0.40m f/8 Ritchey-Chretien telescope (+ Moravian G4-9000 KAF CCD unfiltered CCD camera).

Nova TCP J20210770+2914093 turns into an FeII-type as it keeps rising in brightness
ATel #14816; U. Munari (INAF Padova), S. Moretti, A. Maitan, V. Andreoli (ANS Collaboration)
The transient TCP J20210770+2914093 was discovered by K. Itagaki on 2021 Jul 16.492 UT at unfiltered magnitude 12.0, and classified as a nova by Munari et al. (ATel #14793) based on a spectrum taken on July 17.102 UT.
This initial spectrum resembled novae of the He/N type, with Balmer, HeI, and NII lines present in emission. However, Munari et al. (ATel #14793) warned that with the nova possibly still progressing toward maximum light, the spectral type could evolve toward the FeII type. This has been indeed what happened and here we report about the evolution of the nova during the last two weeks.

We report spectroscopic follow-up observations of Nova Herculis 2021 (TCP J18573095+1653396). It was discovered by Seiji Ueda on 2021-06-12.548 UT and spectroscopically classified as a classical nova by Munari et al. 2021 (ATel #14704). We obtained a low-resolution spectrum with Monte Baldo Observatory 0.25-m Telescope + Alpy 600 spectrograph (380-800 nm, 0.497 nm/px) on 12/06/2021 and 13/06/2021, and a medium resolution spectrum with Asiago 1.22-m 'Galileo' telescope + B&C spectrograph (460-700 nm, resolution 0.25 nm) on 13/06/2021.

Nova Cas 2020 (=V1391 Cas) is likely forming dust
U. Munari (INAF Padova), D. P.K. Banerjee (PRL, India), F. Castellani, S. Dallaporta, A. Maitan, and A. Vagnozzi (ANS Collaboration)
The brightness of the nova has dramatically dropped over the last couple of days with a marked reddening of colors. The presence of a faint and nearby field star, just a few arcsec away from the nova, now requires that the photometry be performed via PSF- fitting. The night values, averaged over PSF-fitting measurements from data that we collected with ANS Collaboration telescopes...(Atel14267) (PDF)
Classification of TCP J04291884+4354232 as a classical nova U. Munari (INAF Padova), F. Castellani, S. Dallaporta, V. Andreoli (ANS Collaboration)

LAMOST J202629.80+423652.0 is not a symbiotic star - V. Andreoli and U. Munari Abstract. LAMOST J202629.80+423652.0 has been recently classied as a new symbiotic star containing a long-period Mira, surrounded by dust (D- type) and displaying in the optical spectra high ionization emission lines, in- cluding the Raman-scattered OVI at 6825 A. We have observed LAMOST J202629.80+423652.0 photometrically in the BVRI bands and spectroscopically over the 3500-8000 A range. (CAOSP Vol.50) (PDF)

The 2018 eruption and long-term evolution of the new high-mass Herbig Ae/Be object Gaia-18azl = VES 263
MNRAS U. Munari, V. Joshi, D. P. K. Banerjee, K. Cotar, S. Y. Shugarov, R. Jurdana-Sepi, R. Belligoli, A. Bergamini, M. Graziani, G. L. Righetti, A. Vagnozzi and P. Valisa
We have been monitoring, at high cadence, the photometric and spectroscopic evolution of VES 263 following the discovery in 2018 of a brightening labelled as event Gaia-18azl.
VES 263 is so far a neglected emission-line object discovered in the 1960s on objective prism plates, tentatively classified as a semiregular AGB cool giant by automated analysis of ASASSN light curves. We have discovered that VES 263 is a bona fide massive pre-mainsequence object (∼12 M), of the Herbig AeBe type. (MNRAS 488, 5536–5550 (2019) (PDF)
Liverpool Telescope classification of optical transients AT2018hho and AT2018hhy

A faint continuum is detected in each case, but the S/N is too low for a classification. AT2018hho was observed at 2018-10-16.94 UT. We detect a Hα emission line with FWHM ~ 3100 km/s. We obtained a spectrum of AT2018hhy at 2018-10-17.99 UT, which shows TiO absorption bands on a red continuum, indicating that this object is a red LPV. We also note that there is a variable coincident with the position of AT2018hhy in Macri et al. (2001) and Hartman et al. (2006). (Atel_12138) (PDF)

After a monotonic - although structured - rise toward maximum, peak brightness has been reached at V=10.90, B-V=+0.85 on June 10, followed by a slow decline. (ATel_10572)
