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.

Hsiao, Florida State University and M. L. Graham (University of Washington) report that a spectrogram (range 390-710 nm, resolution 0.3 nm) of 2017iuu = ATLAS17nnf (J. Tonry, B. Stalder, L. Denneau, A. Heinze, H. Weiland (IfA, University of Hawaii), A. Rest (STScI), K.W. Smith, S. J. Smartt, M. Fulton, O. McBrien (Queen's University Belfast), obtained on Dec. 11.33 UT with the 1.82-m Plaskett Telescope of the National Research Council of Canada, shows it to be a normal type Ia supernova near maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666,1024) suggests that 2017iuu is most similar to the normal type-Ia supernova 1994ae at 3 days past maximum light. There are several possible host galaxies with no published redshifts. Our solution yields a redshift of 0.043 for this object.

Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.0191Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190), we find good fits to several Type Ia supernovae 0-2 weeks before maximum light at a redshift of the proposed host galaxy (z=0.019; Falco et al. 1999, PASP, 111, 438 via NED). We measure a Si II velocity of about 16,000 km/s, implying the supernova was discovered soon after explosion, but the absolute magnitude at discovery was about -19, implying it was discovered near maximum light. Together, these could either indicate a young overluminous supernova or a high-velocity supernova at peak.

Wiggins, Tooele, UT, USA, reports his discovery of a possible supernova (mag about 15.5) on an unfiltered CCD frame taken 2017 Nov 30 10:42:24 UT using a 0.35-m f/5.5 reflector near Erda, UT, USA. The new object is located at R.A. 14h06m23.11s, Decl. +50°43’20.2” (equinox 2000.0), about 15” SE of the center of NGC 5480.

Stanek (OSU)ASAS-SNSN Ia1ASAS-SNWe obtained an optical spectrum of ASASSN-17pk/AT2017iji on UT 2017 Nov. 21.5 with FAST mounted on the FLWO 1.5m telescope. The spectrum is that of a normal Type Ia caught early. The best fit templates with SNID (Blondin & Tonry 2007) are of normal SN Ia at <~1 week before maximum light After correcting the spectrum for the redshift of the host galaxy (z=0.013493), we measure a Si II 6355 Ang. expansion velocity of 14500 km/s from the minimum of the P-Cygni absorption through.
