PNVJ06245297+0208207: likely superhumps
Accoring to Tonny Vanmunster's observations, this AM CVn
object slightly brightened (16.7 mag) on Jan. 23 and showed
likely superhumps (period about 0.035 d).
Please continue observations. Unfortunately there was no
report between Jan. 13 and 22.
ASASSN-23ag: new SU UMa-type dwarf nova
Superhumps were present in Hambsch's data on Jan. 23.
Growing superhumps were likely present on Jan. 21-22
(Vanmunster and Hambsch). Current amplitude 0.05 mag.
Approximate period 0.056 d.
The WZ Sge-type is expected from the outburst amplitude
and the classification as such may become evident as more data
I have just finished analysing my unfiltered CCD observations of
ASASSN-14fx, obtained on 2023, Jan 23/24 at CBA Extremadura Observatory
(Spain) using a 0.40-m f/5.1 telescope and SX-46 CCD camera under clear
The resulting light curve clearly shows the presence of regular superhumps
with an amplitude of 0.24 mag, establishing ASASSN-14fx as a new SU UMa-type
dwarf nova. A period analysis, using the ANOVA, Generalized-Lomb-Scargle,
PDM and Conditional Entropy methods (Peranso 3.0) yields a combined
superhump period of 0.0652 +/- 0.0006d. The object was at mag CV = 16.3 on
I will send my observations to AAVSO, CBA and VSNET for further analysis.
