Gress, Irkutsk State University et. al. report on The Astronomer Telegram 6634 the detection by MASTER-Tunka of an OT source at: RA 12h 04m 51.50s DEC +26 59' 46.6" (2000) on 2014 Oct 28.874UT. The OT, with preliminary designation J120451.50+265946.6 had an unfiltered magnitude of 13.9 (limit 18.1m). The OT is seen in seven images. There is no minor planet at this place. A reference image is held without the OT on 2011 Apr 21.674UT with unfiltered magnitude limit 20.2. The OT is located 4" west and 13" north of the centre of the galaxy NGC 4080. Spectral confirmation is required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/120451.50265946.6.png We are not aware the object, as yet, has been confirmed spectroscopically. SUPERNOVA 2014dt IN NGC 4303 = MESSIER 61 (ITAGAKI) 2014dt Oct 29.83 12 21 57.57 +04 28 18.5 13.6 33.9"E 7.2"S The object reported on TA E-Circular 3035 has been spectroscopically confirmed and designated SN 2014dt. The type-II supernovae 1961I (cf. IAUC 1761), 1964F (IAUC 1868), and 1999gn (IAUC 7335) also appeared in NGC 4303, as did SN 1926A (IAUC 111). P. Ochner: spectrum Oct 31 shows peculiar type-Ia, perhaps of type-Iax class. Guy M Hurst
