"Type Ia supernova science working group of the Palomar Transient Fact=

on g-band images obtained with the Oschin 1.2-m Schmidt telescope at Paloma=

on Aug. 24 UT. =C2=A0The supernova is located at R.A. =3D 14h03m05s.81, Dec=

+54d16'25".4 (equinox 2000.0), which (according to D. Bishop, Roch=

USA) is 59" west and 271" south of the center of M101; nothing wa=
s visible at

this position on an image from Aug. 23 (limiting mag 20.6). =C2=A0The varia=
ble was

designated PSN J14030581+5416254 when posted on Aug. 24.99 on the Central r>
Bureau's TOCP webpage by Bishop and is here designated SN 2011fe based =
on the

spectroscopic report below by Nugent et al. =C2=A0A preliminary spectrum ob=
tained

on Aug. 24 UT with FRODOSPEC on the Liverpool Telescope indicates that 2011=
fe

is probably a very young type-Ia supernova; broad absorption lines

(particularly the Ca II infrared triplet) are visible. =C2=A0The presence o=

H-alpha feature is confidently rejected.
