K. Sahu et. al., of the India Institute of Astrophysics, Bangalore, India has reported on ATEL 6673 classification of PSN J17143828+4340517 in an anonymous galaxy. Low resolution spectra (range 350 - 920 nm) were obtained on 2014 November 6.77UT. They used the 2-m Himalayan Chandra Telescope (+HFOSC) at the Indian Astronomical Observatory emphasising large apertures needed for mag 17 spectra. The spectra showed a prominent SiII (635.5 nm) line. The SuperNova IDentification code SNID provides a best match with a normal type-Ia supernova SN 2004eo, a few days before maximum light, at a redshift of 0.031. Correcting for the redshift of the host the expansion velocity measured with respect to the minimum of the SiII (635.5 nm) line is ~10,500 km/sec. Although the discovery and prediscovery details were posted by Ron Arbour to CBAT "Transient Object Followup Reports" WWW page the spectral confirmation is missing. As a result the object has not yet received a designation or been announced by Dan Green on CBET. NEW POSSIBLE WZ SGE VARIABLE: ASASSN-14JV Astronomer's Telegram (ATel) #6676 notes the discovery of ASASSN-14jv, a bright optical transient found at V=11.3 on 2014 November 9.19 (JD 2456970.69). This object is suspected to be a cataclysmic variable of the WZ Sge subtype. Shappee et al. note that the source is less than one arcsecond away from a g=19.1 magnitude source in the Kepler Input Catalog, suggesting a large amplitude typical of UGWZ stars. The object is quite blue, according to observations by A. Pal et al. (ATel #6680, 2014) that show the transient on 2014 Nov. 9.78 UT at B=10.7 +/-0.2, V=11.3 +/- 0.2, and R=11.9 +/- 0.2, based on USNO B1.0 magnitudes. Observations by Enrique de Miguel (CBA Huelva, Spain) reported on 9 November 2014 [vsnet-alert 17950] show the presence of probable superhumps. That, combined with the large amplitude and colour, indicates that the object is likely a WZ Sge star. Both photometric (CCD and visual) and spectroscopic observations are encouraged, spectroscopy especially to confirm the nature of the object. ASASSN-14jv is located at: RA 18h53m28.81s DEC +42 03' 43.3" (2000) Charts for ASASSN-14jv may be created using the AAVSO Variable Star Plotter (VSP, www.aavso.org/vsp). A sequence is being created and will be available via VSP once it has been uploaded. (AAVSO Special Notice #390) Guy M Hurst
