The PSN is visible on several images (limiting magnitude about 18.2) taken at 2017 12 13.88 UT from MPC K82. The new object is located at A.R. = 02h 11m 15.36s, Decl. = +37° 29’ 48.3” (equinox 2000.0, astrometry with respect to UCAC-4 catalogue) which is 24 arcsec west and 2 arcsec south of the center of Galaxy NGC 841. Checked Minor Planet Center for asteroids and VSX for variable stars.

Campillay (LCO)NoneLBV0.0015581The spectrum is blue with Balmer and He I P-Cygni features and several strong absorption features including Ca H&K and several Fe II lines. The spectrum is generically similar to 'cool' LBV outbursts such as UGC 2773 OT-1 (Smith et al., 2010, AJ, 193, 1451; Foley et al., 2011, ApJ, 732, 32). The spectrum is also similar to the Type IIn SN 1994W (Sollerman et al., 1998, ApJ, 493, 933). Correcting for the small redshift of NGC 0045 (cz = 467 km/s; Monnier Ragaigne et al., 2003, A&A, 408, 465), we find that the minimum of the H-alpha absorption for AT 2018htr is blueshifted by -1240 km/s. The absorption feature extends to approximately -2100 km/s. ATel: 12166

The SNIIn/LBV is likely in the host-galaxy NGC 300 (z = 0.00048; NED value). Taken at Gemini-S using GMOS. At the distance of NGC300 (distance modulus of 25.83; NED value) the object’s magnitude Mr=-8.5 is more consistent with an LBV (or very young SN IIn). An H-alpha P-cygni absorption was measured at 2000 km/s

McCullyGlobal SN ProjectSN Ia0.0081Global SN ProjectUsing SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find a good fit to the normal Type Ia SN 2002bo 13 days before maximum light at redshift z=-0.001. This negative redshift from SNID, compared to the host galaxy redshift of z=0.008 (Cappellari et al. 2011, MNRAS, 413, 813), likely indicates that the supernova is even younger than -13 days.

Guhathakurta (UCSC)UCSCLBV0.0061UCSCRed spectrum (black body temperature ~ 4,500 K, assuming no host extinction) with a distinctive narrow H-alpha emission feature (FWHM ~ 1300 km/s), red-shifted at 260 km/s relative to the host (NGC 718, with spectroscopic redshift z = 0.005781). The (observed) absolute magnitude of the transient is M_r = -13.3, and dereddening by an appropriate amount to match the Na D absorption strength (EW ~ 6 Angstroms), we estimate a temperature of 15,700 K and an absolute magnitude of ~ -16. We consider these properties most similar to a reddened LBV outburst, however it is also consistent with a luminous red nova. We thank the Lick Observatory staff for helping with these target-of-opportunity observations. ATel: 13263

30872018-11-24 16:17:26myamanakaMasayuki YamanakaNoneSN II0.003791We obtained the low-resolution spectrum of AT 2018ivc using the HOWPol attached to the 1.5-m Kanata telescope on Nov. 24.6 in 2018. The spectrum exhibits the featureless blue continuum, suggesting that this SN is classified as a young core collapse SN. GELATO (Harutyunyan et al., 2008, A&A, 488, 383) suggests that this SN is similar to that of Type II SN 2009bw at 4 days after the explosion date.
