SN 2001P has discovered and confirmed on Jan. 31.4 UT and Feb. 1.3 UT, respectively. The discovery magnitude is reported as 17.5:C. The location is about 17" east and 13" south of the nucleus of the barred-spiral galaxy NGC 3947. From the recession velocity of NGC 3947, the expected maximum for normal SN Ia is about mag 16. Note that NGC 3947 has produced SN 1972C, which was caught at m_p = 16. The Spectroscopy of SN 2001P has revealed that it was of type Ia about a week past maximum, and it seems to be subluminous (vsnet-campaign-sn 148).
