AT 2026lxf  - CV Type Transient

AT 2026lxf (Bootes) AT 2026lxf (Type: CV) discovered 2026-05-08.326 UT by Claudio Balcon Alias: TCP J15030519+2202041 Discovery Magnitude 13.9 (Clear- Filter) vs Prior Non-Detection Limiting Magnitude 15 (Clear- Filter) Dwarf nova candidate found with the NMW-TexasTech survey using two identical 135mm telephoto lenses + unfiltered QHY600M CMOS cameras. The transient was first detected on 2026-05-08.3260 UTC at CV=13.95 with one camera and confirmed in images taken with the second camera 78 minutes later on 2026-05-08.3803 at CV=14.01. The magnitude difference is not significant given the expected photometric uncertainty of 0.06 mag. The object was not detected above the magnitude limit of CV~15 on the images taken the previous night on 2026-05-07.4551. A blue Pan-STARRS 1 DR2 source PS1 134442257714871804 (g=21.38 +/-0.04, r=21.50 +/-0.05) is located at 15:03:05.16 +22:02:03.6 J2000, just 0.6" from the measured position of the transient (NMW-TexasTech image scale is 5.9"/pix). The plate-solved FITS images, finder charts and animations produced from the NMW-TexasTech images are available at https://tau.kirx.net/img/TCPJ15030519+2202041/ The NMW-TexasTech survey operates at TTU Preston Gott Skyview Observatory (Shallowater, Texas).
