Planetario Verona Vicino A Te

4worldlovers: Astrofili Lessinia Orientale nasce come ramo del Gruppo Gastrofili Val d'Alpone - APS

4worldlovers: Durante il periodo primaverile ed estivo sono organizzate una serie di aperture pubbliche aperte a tutti. Non serve prenotazione

Visite per le scuole di ogni tipo e livello, con lezione e osservazione sia del Sole di giorno, sia degli oggetti celesti alla sera.

Lo stage di Astronomia per i ragazzi del IV anno delle scuole superiori è stata una esperienza formativa dell'astronomia dal 2012 al 2016


Remarks: During the 2022 internship involving a group of high school students at the Monte Baldo Astronomical Observatory (hereafter referred to as OMB) in Ferrara di Monte Baldo, Verona, Italy, the two stellar systemsclassification. See more (20230608-ArticoloStage2022)


Remarks: Andreoli.V ; Castellani.F report/s a classification of object: AT 2023dez. Low resolution spectrum (6 X 600s) was obtained on 2023-03-17.802 from Osservatorio Monte Baldo located in Novezzina (Italy) by 0.25-m telescope + Alpy600 spectrograph (with dispersion 4.9 Ang/pix). The spectrum shows H-alpha emission (6562.8 Ang), a weak absorpion of H-beta (4861.03) problably filled up by the accretion disk and strong absorpions of the other Balmer lines and He I (4471;4922;5876 Ang). It also shows interstellar NaI D1,D2 (5885,5890 Ang). These features belong to a type Be Herbig star. Furthermore the coordinates are coincident to LS I+56 76, object prensent in the Catalog of galactig OB stars (Reed 2003). We propose the identification for this transient as a Be star.


Remarks: Andreoli.V ; Castellani.F ; Vesentini.F report/s a classification of object: AT 2023cub. Low resolution spectrum (5 X 600s) was obtained by 0.25-m telescope + Alpy600 spectrograph (with dispersion 4.9 Ang/pix) located in Novezzina (Italy) on 2023-03-09.792. The spectrum shows red continuum and absorption of H-alpha (6562.825 Ang), H-Beta (4861.03 Ang), D1,D2 Na doublet (5885;5890 Ang) and Ca I (4302 Ang) ; also the coordinates are coincident to V*520Mon (MAXI J0655-013) and at these coordinates an hard X-ray was detected (Serino et al. ATel #15442). We propose the identification of the transient as a brightness of the X-ray variable. (Classification-cert) (AT2023cub)


Remarks: Flavio Castellani, Claudio Balcon and Vittorio Andreoli reports: We obtained BVRI photometry of PNV J01345297+3047145 (AT 2023bne) with 0.4m telescope + Moravian G4 CCD full frame located in Novezzina (Italy), date 2023/02/11.7868 B=17.11 ; V=17.04 ; R=17.01 ; I=16.84 (Vphot AAVSO photometry tool). Color index B-V=0.07 is similar to cataclysmic variable (CV) Z Cam B-V=0.05 (Bruch 1984) at maximum. We also obtained two low resolution spectra (2x2400s , R=100) by 0.2m telescope on 2023-02-11.772 UT, the spectrum shows a blue continuum with no features above noise level. These characteristics are compatible with those of a CV in outburst. (Classification-cert) (AT2023bne)


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").

LAMOST J202629.80+423652.0 is not a symbiotic star - V. Andreoli and U. Munari Abstract. LAMOST J202629.80+423652.0 has been recently classi ed 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)


Remarks: F. Castellani, Verona, Italy reports the discovery by Flavio Castellani, Raffaele Belligoli and Claudio Marangoni, in the course of the ISSP Italian Supernovae Search Project, of an apparent nova in two images taken with a Moravian G4-9000 KAF CCD unfiltered, from Monte Baldo Observatory (Ferrara di Monte Baldo, Verona, Italy), with the 0.4m f.8 Ritchey-Chrétien telescope, obtained on 2020 March 04.7596. The new object is located at RA 00 42 08.56 DEC +41 26 00.8 (equinox 2000.0) Apparent magnitude about 18.0 in host Galaxy M31 Nothing is visible at this position on the reference image taken on 2020-02-28.769...
