[vsnet-alert 23735] ASASSN-19abi: new *eclipsing* WZ Sge-type dwarf nova

[Tonny Vanmunster tonny.vanmunster@gmail.com via vsnet-alert]

Dear all,

 

On Nov 17th, 2019, I reported the detection of early superhumps in ASASSN-19abi, establishing this object as a new WZ Sge-type dwarf nova. I have just concluded the analysis of my 2019, Nov 23/24 unfiltered CCD photometry session of ASASSN-19abi. Observations were made at CBA Extremadura Observatory, using a 0.40-m f/5.1 telescope and SX-46 CCD camera, under (initially) clear skies. 

The resulting light curve clearly shows the presence of eclipses in the light curve, hence establishing ASASSN-19abi as an *eclipsing* WZ Sge-type dwarf nova. Eclipses are approx. 0.4 mag deep. 


Observations will be sent to AAVSO, CBA and VSNET for further analysis. 

Follow-up observations are evidently highly recommended. 

Best regards
Tonny
