The Nearby Supernova Factory reports the discovery of 16 supernovae in images obtained during the month of September, using the QUEST II camera on the Palomar Oschin 48-inch telescope. Images obtained prior to September 20 were acquired in point-and-track mode as a part of the JPL Near-Earth Asteroid Tracking component of the Palomar-QUEST Consortium. Images obtained after this date were acquired in drift-scan mode, in conjunction with the Palomar-QUEST Consortium. A subsequent spectrum of each target (range 320-1000 nm) obtained with the Supernova Integral Field Spectrograph on the University of Hawaii 2.2-meter telescope was used for classification.

All coordinates are J2000.0. Supernovae SNF20060911-006 and SNF20060911-013 were discovered a few days before maximum. Supernovae SNF20060906-011, SNF20060913-005, and SNF20060913-010 were discovered at maximum. Supernovae SNF20060919-008 and SNF20060923-001 were discovered approximately one week after maximum. Supernova SNF20060911-000 was discovered two months past maximum.
