RA 11h 51′ 02″, Dec. –28° 44′ 38″. Although low in the sky for observers in the northern U.S., I saw it without difficulty from 47°N in my 15-inch reflector at 142× on April 8th UT. The SN is about 4′ due north of the galaxy's nucleus and photographed here (tick marks) on April 7th. (http://wwwcdn.skyandtelescope.com/wp-content/uploads/SN-3923-Stan-Howerton-768x631.jpg) |
