[vsnet-alert 28020] V854 Cen Possible Fade
by Peter Williams 30 Sep '24

30 Sep '24

The RCB star V854 Cen has just recovered from a deep decline that lasted from January through July 2024. During September 2024 it gradually faded again to visual magnitude 8.1, but it is not clear if this is the onset of another deep decline. It has been cloudy for the past week here at Heathcote NSW , so I have been unable to confirm the current state of V854 Cen. A check on this star would be appreciated - thanks.

TCP J17064645-3528079: new classical nova TCP J17064645-3528079 was discovered by Koichi Itagaki on 2024-09-09.4363 UT at 11.4 mag. I reported the optical spectrum of TCP J17064645-3528079 to ATel and classified it as a new classical nova eruption. https://www.astronomerstelegram.org/?read=16808 Further observations are encouraged.

[vsnet-alert 28018] ASASSN-24fq: new SU UMa-type dwarf nova
by tonny.vanmunster＠gmail.com 02 Sep '24

02 Sep '24

Dear colleagues, I have just finished analysing my unfiltered CCD observations of ASASSN-24fq, obtained on 2024, Aug 30/Sep 01 and Sep 01/02 at CBA Extremadura Observatory using a 0.40-m f/5.1 telescope and SX-46 CCD camera under clear skies. The resulting light curve clearly shows the presence of regular superhumps with an amplitude of 0.56 mag, establishing ASASSN-24fq as a new SU UMa-type dwarf nova. A period analysis, using the ANOVA, Lomb-Scargle, Generalized-Lomb-Scargle, PDM … [View More]
