Vendégcsillag-kereső

During the regular check of my CCD images of M31 within the framework of our Vend-RNe program on 12.0664UT November 2022 I discovered a 16.6C bright possible nova at the following approximate position: 00 42 47.23 +41 16 19.8  (J2000.0). Update: it seem this is an independent discovery of PNV J00424719+4116196 which is probably identical with the recurrent nova M31N 1984-07a. My images were made around half day before the XOSS team discovery images. Update 2: M31N 2022-11b: Additional Photometry and Confirmation as the Fourth Reported Eruption of the M31 Recurrent Nova M31N 1984-07a ( ATEL #15779 ) The possible nova is clearly visible on the subtracted images (new image: 11/12 November, reference image: 10/11 November). The possible nova on my 4x45s stacked images made on 12th November 2022 01:35 UT with the 0.43-m f/6.8 reflector remotely at Mayhill, New Mexico, US using Luminance filter.

I discovered a new symbiotic variable star, Vend47 in outburts during course of our "Vendégcsillag-kereső" /Guest Star Hunter/ Programme. Update: symbiotic nova outburst of Vend47 (=V426 Sge) detected in 1968. Vend47 was found  on my 4x60s DSLR images of my "QW Sge" field made Canon EOS 1000D camera with 180mm focus telephoto lens in Zsámbék , Hungary. The star was 12.0TG on 31.9451 July and 11.66TG on 3,9886 Aug. and 10.7TG on 08.9381 Aug. VSX listed an SR variable ASASSN-V J195442.95+172212.6 with a range between 12.16-12.84V with 418 days period. ASAS-SN data show a sudden rise from 12.025C on 05.49 August to 11.113V on 06.3317 Aug -- a strange fast brightening for an SR variable with 418 days period. So I suggested it was a symbiotic variable in outburst when it was submitted to the IAU Central Bureau for Astronomical Telegrams Transient Object Confirmation Page (TOCP) as a new discovery  where it was designated TCP J19544251+1722281 .
