The Italian Supernovae Search Project (ISSP) is the new collaboration between the main four rItalian groups operating in the extragalactic supernova research field: the CROSS of Col Drusciè Observatory - Cortina d'Ampezzo (Belluno), the MOSS of Montarrenti Observatory (Siena), the MASACAS of Monte Agliale Observatory (Lucca) and the MVSS of Montecatini Val di Cecina Observatory (Pisa).

The collaboration aims to create a joint supernova research program that allows to monitor many stellar field as frequently as possible searching for supernova explosions.

SUPERNOVA 2014dd IN UGC 2504 = PSN J03033627+4656520
F. Ciabattari, E. Mazzoni, and R. Simonetti, Borgo a Mozzano, Italy,
report the discovery of an apparent supernova (mag 17.3) on unfiltered CCD
images (limiting magnitude 19.5) obtained on Aug. 29.06 and 30.04 UT with a
0.5-m Newtonian telescope (+ FLI 4710 Proline camera).  The new object is
located at R.A. = 3h03m36s.27, Decl. = +46d56'52".0 (equinox 2000.0;
astrometry with respect to UCAC-2 stars), which is 5" west and 14" north of
the center of the galaxy UGC 2504.  Nothing is visible at this position on
digitized plates of the Palomar Sky Survey from 1989 Oct. 1 (F plate; limiting
magnitude 20.3) and 1993 Sept. 24 (J plate; limiting magnitude 20.3).  The
variable was designated PSN J03033627+4656520 when it was posted at the
Central Bureau's TOCP webpage and is here designated SN 2014dd based on the
spectroscopic confirmation reported below.  Additional CCD magnitudes for
2014dd:  2014 Aug. 30.965, 17.3 (G. Masi, P. Catalano, and P. Schmeer;
remotely using a 43-cm telescope at Ceccano, Italy; position end figures
36s.19, 51".8); Aug. 31.329, 17.9 (J. Brimacombe, Cairns, Australia; remotely
using a 51-cm RCOS telescope + STXL-6303 camera at the New Mexico Skies
observatory near Mayhill, NM, USA; position end figures 36s.15, 52".0; image

S. T. Hodgkin, A. Hall, M. Fraser, and H. Campbell, University of
Cambridge; L. Wyrzykowski and Z. Kostrzewa-Rutkowska, Warsaw Observatory; and
N. Pietro, Isaac Newton Group, Warwick University, report that a spectrogram
(range 350-800 nm; resolution about 0.6 nm) was obtained of PSN
J03033627+4656520 (= SN 2014dd) with the 2.5-m Isaac Newton Telescope (+
Intermediate Dispersion Spectrograph + R300V grating) at La Palma on Sept.
4.17 UT.  The spectrum was compared to a set of templates using SNID (Blondin
and Tonry 2007, Ap.J. 666, 1024), and a good match was found to a type-Ia
supernova around one month after maximum light.  The redshift of 2014dd is
consistent with that of the host galaxy (z = 0.0235, from the NASA
Extragalactic Database).

SUPERNOVA 2014cg IN UGC 11512 = PSN J20043485+1244168
     F. Ciabattari, E. Mazzoni, and G. Petroni, Borgo a Mozzano, Italy, 
report
their discovery of an apparent supernova (mag 17.8) on unfiltered CCD images
(limiting magnitude 19.5) obtained on July 18.95 and 19.92 UT with a 0.5-m
Newtonian telescope (+ FLI 4710 Proline camera).  The new object is located 
at
R.A. = 20h04m34s.85, Decl. = +12d44'16".8 (equinox 2000.0; astrometry with
respect to UCAC-2 stars), which is 4" east and 7" south of the center of
the
galaxy UGC 11512.  Nothing is visible at this position on the digitized 
plates
of the Palomar Sky Survey from 1992 July 27 (J plate; limiting mag 20.3) and
1992 Sept. 27 (F plate; limiting mag 20.3).  The variable was designated PSN
J20043485+1244168 when it was posted at the Central Bureau's TOCP webpage 
and
is here designated SN 2014cg based on the spectroscopic confirmation 
reported
below.  Additional CCD magnitudes for 2014cg:  2014 July 4, [19.5 
(Ciabattari
et al.); 22.344, 18.3 (J. Brimacombe, Cairns, Australia; remotely using a
51-cm RCOS telescope + + luminance filter at the New Mexico Skies 
observatory
near Mayhill, NM, U.S.A.; position end figures 34s.83, 17".5; image posted 
at
website URL https://www.flickr.com/photos/43846774@N02/14543018109/); 
25.823,
18.2 (G. Masi; remotely using a 43-cm telescope at Ceccano, Italy; position
end figures 34s.84, 16".2).

     J. Zhang, Yunnan Observatories (YNAO); and X.-f. Wang, Tsinghua
University, report on an optical spectrogram (range 330-890 nm) of 2014cg 
that
was obtained on 2014 July 24.68 UT with the 2.4-m telescope (+ YFOSC) at the
LiJiang Gaomeigu Station of YNAO.  The spectrum shows that PSN
J20043485+1244168 = SN 2014cg is a type-Ia supernova a few days after 
maximum
light.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) shows that 2014cg matches with SN 2005cg at +7 days.  Adopting a
redshift of 0.0147 for the host galaxy, UGC 11512 (Huchra et al. 1999, Ap.J.
Suppl. 121, 287), they measure a velocity of the Si II 635.5-nm absorption
feature to be about 10300 km/s.  The continuum of the spectrum is very red,
suggesting that this supernova may suffer significant reddening from the 
host
galaxy.
