SUPERNOVA 2010hf IN MCG +09-11-21

T. Boles, Coddenham, England, reports the discovery of an apparent
supernova (mag 18.3) on unfiltered CCD images taken on Aug. 31.114 and 31.894
with a 0.35-m reflector. The new object is located at R.A. = 6h37m19s.77
+/- 0s.02, Decl. = +56o22'57".8 +/- 0".2 (equinox 2000.0), which is
approximately 5".6 west and 11".8 north of the center of MCG +09-11-21.
Nothing is present at this position on Boles's images from 2010 Mar. 2 and
2009 Sept. 25 (limiting mag 19.5) or on Digitized Sky Survey plates from 1991
Feb. 8 (limiting red mag 20.5) and 1991 Dec. 12 (limiting blue mag 21.0).

SUPERNOVA 2010hg IN NGC 3001

L. A. G. Monard, Pretoria, S. Africa, reports his discovery of an
apparent supernova (magnitude 15.0) on several unfiltered CCD images taken
on Sept. 1.143 UT at the Bronberg Observatory. The new object, which was
confirmed at mag 14.7 via images taken on Sept. 2.138, is located at R.A. =
9h46m13s.7, Decl. = -30d27'13".3 (equinox 2000.0), or 64" west and 58" south
of the core of the nearby type-Sbc galaxy NGC 3001; 2010hg is located in or
near one of the outer spiral arms. Nothing is seen at this position on
Digitized Sky Survey images (limiting red mag 20.5) or on the previous image
of this galaxy taken at the Bronberg Observatory on Aug. 2.690 (limiting mag
18.0) or on earlier images from there.

SUPERNOVA 2010hi IN NGC 6621

Ron Arbour, South Wonston, Hants, U.K., reports his discovery of an
apparent supernova (mag 18.0) on unfiltered CCD images taken on Sept.
1.893 (limiting mag 19.2) and 2.883 UT using a 0.4-m f/5 Newtonian
reflector (+ Starlight Xpress camera) in the course of his supernova
patrol. The new object is located at R.A. = 18h13m00s.76, Decl. =
+68d21'53".4 (equinox 2000.0), which is 30" east and 4" north of the

SUPERNOVAE 2010hf IN MCG +09-11-21

G. H. Marion and P. Challis, Harvard-Smithsonian Center for Astrophysics
(CfA), on behalf of the CfA Supernova Group, report that a low-signal-to-noise
spectrum (range 360-740 nm) of 2010hf (cf. CBET 2432), obtained on Sept. 2 UT
by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST),
shows 2010hf to be a type-IIb supernova. Cross-correlation with a library of
supernova spectra using the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024) provides the best fit to spectra from SN
1993J obtained a few days after maximum light.

National University; S. Howerton, Arkansas City, KS, U.S.A., J. L. Prieto,
Carnegie Observatories; M. Catelan, Pontificia Universidad Catolica de Chile;
E. C. Beshore and S. M. Larson, Lunar and Planetary Laboratory, University of
Arizona; and E. Christensen, Gemini Observatory, report the discovery of an
apparent supernova in unfiltered Siding Spring Survey (SSS) images:

SN 2010 UT R.A. (2000.0) Decl. Mag. Offset
2010hj Aug. 4.61 21 49 09.84 -59 02 23.2 17.1 5".5 W, 8".2 S

Nothing was visible at this position on an SSS image from 2009 Oct. 1.50 UT
(limitiing mag 18.9), but 2010hj was detected again in SSS images on Aug.
29.59 (no magnitude provided). The host galaxy appears to be PGC 67413 = ESO
145-G16. Joseph Brimacombe, Cairns, Australia, reports that ten stacked 600-s
CCD images (limiting magnitude 20) taken remotely with a 32-cm RCOS telescope
(+ STL6K camera + clear filter) at the Macedon Ranges Observatory near
Melbourne, Australia, on Aug. 29.727 show the new object to be at mag 18.3
and located approximately 7" west and 7" south of the presumed host-galaxy
nucleus. Another stacked image (seven 1200-s frames; limiting magnitude 20),
taken by Brimacombe on Sept. 2.636 with a 40-cm RCOS telescope (+ U16 camera
+ red filter) at the Coral Towers Observatory (Cairns), yields mag 18.6 for
2010hj; the Sept. 2 stacked image has been posted at the following website

SUPERNOVA 2010hh IN NGC 6524

S. Nakano, Sumoto, Japan, reports that K. Kadota (Ageo, Japan) obtained
a co-added image (limiting mag 18.6) of 2010hh (cf. CBETs 2435, 2440) from
twelve 120-s unfiltered CCD frames taken around Sept. 3.675 UT with a 0.25-m
f/5 reflector (+ SBIG ST-9E camera), yielding mag 17.7 and position R.A. =
17h59m18s.39, Decl. = +45d52'32".1 (equinox 2000.0).

J. M. Silverman, J. Choi, A. V. Filippenko, and F. J. D. Serduke,
University of California, Berkeley, report that inspection of a CCD spectrum
(range 340-970 nm), obtained on SepT. 3 UT with the 3-m Shane reflector (+
Kast) at Lick Observatory, shows that 2010hh is a type-Ia supernova near
maximum brightness. After removal of the host-galaxy recession velocity of
5698 km/s (Falco et al. 1999, PASP 111, 438), the absorption minimum of the
Si II 635.5-nm line is found to be blueshifted by about 12600 km/s. The Si
II line at 597 nm is quite strong, as is Ti II absorption around 420-430 nm,
suggesting that 2010hh is subluminous like SN 1991bg (e.g. Filippenko et al.
1992, AJ 104, 1543), though perhaps not quite as extreme.

SUPERNOVAE 2010hk AND 2010ho

G. H. Marion and P. Challis, Harvard-Smithsonian Center for Astrophysics
(CfA), on behalf of the CfA Supernova Group, report on spectroscopic
observations (range 340-740 nm) of 2010hk (cf. CBET 2439) obtained on Sept. 4
UT by P. Berlind and of 2010ho (cf. CBET 2445) on Sept. 5 UT by M. Calkins
with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-
correlation with a library of supernova spectra using the "Supernova
Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows
that both 2010hk and 2010ho are normal type-Ia supernovae at a few days past
maximum light.

superseded by text appearing later in the printed IAU Circulars.

APPARENT NOVA IN M31: M31N 2010-09a

Syuichi Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata) of an apparent nova (mag 17.2) in M31 on unfiltered CCD
frames (limiting magnitude 20.5) taken on Sept. 4.552 UT using a 0.60-m f/5.7
reflector (+ Bitran BT-214E camera). The new object is located at R.A. =
0h42m23s.32 +/- 0s.03, Decl. = +42o17'08".6 +/- 0".3 (equinox 2000.0).
Additional magnitudes for M31N 2010-09a measured by Itagaki: 1986 Nov. 27,
[21.0 (Digitized Sky Survey red plate); 2007 Oct. 13, 20.0; 2010 Aug. 21.631,
[19.0; Sept. 1.666, 17.8 (pre-discovery); 5.490, 18.1 (limiting mag 20.5).
The discovery image is visible at http://www.k-itagaki.jp/images/pn-m-31.jpg.
Nakano also forwards a confirming report by T. Yusa (Osaki) on Sept. 5.500,
in which an unfiltered CCD image taken with a 0.30-m f/9.9 Cassegrain telescope
(+ BSTL-1001E camera) shows M31N 2010-09a at mag 17.5 and with position end
figures 23s.29, 08".9.

SUPERNOVA 2010hp IN MCG -02-01-52

G. H. Marion and P. Challis, Harvard-Smithsonian Center for Astrophysics
(CfA), on behalf of the CfA Supernova Group, report that a spectrum (range
340-740 nm) of 2010hp (cf. CBET 2446) was obtained on Sept. 8 UT by P. Berlind
with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation
with a library of supernova spectra using the "Supernova Identification" code
(SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that 2010hp is a type-II
supernova more than 30 days past maximum light.

SUPERNOVA 2010hq IN UGC 3691

L. A. G. Monard, Pretoria, South Africa, reports his discovery of an
apparent supernova (mag 15.2) on an unfiltered CCD image taken on Sept. 8.136
UT at the Bronberg Observatory. The new object, which was confirmed at mag
15.3 on Sept. 9.136, is located at R.A. = 7h08m03s.35, Decl. = +15o11'10".0
(equinox 2000.0), which is 29" east and 25" north of the galaxy core of UGC
3691. Nothing is shown at this position in Digitized Sky Survey images
(limiting red mag 20.5).
