We present 1210 Johnson/Cousins B, V, R, and I photometric observations of 22 recent Type Ia supernovae (SNe Ia): SNe 1993ac, 1993ae, 1994M, 1994S, 1994T, 1994Q, 1994ae, 1995D, 1995E, 1995al, 1995ac, 1995ak, 1995bd, 1996C, 1996X, 1996Z, 1996ab, 1996ai, 1996bk, 1996bl, 1996bo, and 1996bv. Most of the photometry was obtained at the Fred Lawrence Whipple Observatory of the Harvard-Smithsonian Center for Astrophysics in a cooperative observing plan aimed at improving the database for SNe Ia.

BVRI Photometry of Supernovae

We present optical photometry of one Type IIn supernova (1994Y) and nine Type Ia supernovae (1993Y, 1993Z, 1993ae, 1994B, 1994C, 1994M, 1994Q, 1994ae, and 1995D). SN 1993Y and SN 1993Z appear to be

The Luminous Type Ic Supernova 1992ar at z = 0.145

We present spectroscopic and photometric observations of SN 1992ar, the most distant supernova (SN) in the Calán/Tololo Survey. We compare its spectrum with those of nearby Type Ia and Ic SNe and

Observations of five supernovae in 1995–1997

We present the results of photometric observations of the type Ia supernovae SN 1995al, 1996bo, 1996bk, the type Ib/c supernova SN 1997X, and the type II supernova SN 1996an. The photometric

The template type Ia supernova 1996X

ABSTRA C T UBVRIJ photometry and optical spectra of the type Ia SN 1996X obtained at the European Southern Observatory (ESO) during a 1-yr-long observational campaign are presented, and supplemented

ESC observations of SN 2005cf – I. Photometric evolution of a normal type Ia supernova

We present early-time optical and near-infrared photometry of supernova (SN) 2005cf. The observations, spanning a period from about 12 d before to 3 months after maximum, have been obtained through

Uniformity of (V–Near-Infrared) Color Evolution of Type Ia Supernovae and Implications for Host Galaxy Extinction Determination

From an analysis of SNe 1972E, 1980N, 1981B, 1981D, 1983R, 1998bu, 1999cl, and 1999cp, we find that the intrinsic V-K colors of Type Ia SNe of typical luminosity (i.e., with multicolor light-curve

Optical and Infrared Photometry of the Type Ia Supernovae 1999da, 1999dk, 1999gp, 2000bk, and 2000ce

We present BVRI photometry of the Type Ia supernovae 1999da, 1999dk, 1999gp, 2000bk, and 2000ce, plus infrared photometry of three of these. These objects exhibit the full range of decline rates of

SN 2002cv: a heavily obscured Type Ia supernova

We present V RIJHK photometry, and optical and near-infrared spectroscopy, of the heavily extinguished Type Ia supernova (SN) 2002cv, located in NGC 3190, which is also the parent galaxy of the Type

The underluminous Type Ia supernova 2005bl and the class of objects similar to SN 1991bg

Optical observations of the Type Ia supernova (SN Ia) 2005bl in NGC 4070, obtained from 6 to +66d with respect to the B-band maximum, are presented. The photometric evolution is characterised by

The Type Ia Supernova 1998bu in M96 and the Hubble Constant

We present optical and near-infrared photometry and spectroscopy of the Type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measurements and 29



CCD photometry of three Type Ia supernovae: V, R, and I light curves

Cousins system VRI photometry has been obtained for the Type Ia supernova 1992 G with CCDs attached to small telescopes at Leuschner Observatory (LO), Van Vleck Observatory (VVO), and Whitin

Cepheid Calibration of the Peak Brightness of Type Ia Supernovae: Calibration of SN 1990N in NGC 4639 Averaged with Six Earlier Type Ia Supernova Calibrations to Give H0 Directly

Periods and light curves have been measured with the Hubble Space Telescope for 20 Cepheids in NGC 4639, parent galaxy to the Type Ia, prototypical supernova SN 1990N. The periods range from 17 to 69

Time Dilation in the Light Curve of the Distant Type Ia Supernova SN 1995K

The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first

The Peak Brightness of SN 1895B in NGC 5253 and the Hubble Constant

The light curve of the Type Ia supernova SN 1895B (in NGC 5253) is important because Sandage et al. have measured a distance to the host galaxy by means of Cepheid variables and thus have derived the

Type Ia Supernovae as Standard Candles

Observations are compiled to construct a mean light curve of SNe I in different colors. Individual SNeI show generally no systematic deviations from these templet light curves, and occasional

A Supernova at z = 0.458 and Implications for Measuring theCosmological Deceleration

We have begun a program to discover high-redshift supernovae ($z \approx$ 0.25--0.5), and study them with follow-up photometry and spectroscopy. We report here our first discovery, a supernova at $z

The Cepheid distance to IC 4182 : calibration of MV(max) for SN Ia 1937C and the value of H0

Cepheid variables with periods from 2 to more than 50 days have been found in IC 4182 from observations with the Hubble Space Telescope over a time interval of 47 days, comprised of 20 epochs. The

The Hubble diagram of the Calan/Tololo type IA supernovae and the value of HO

The Calan/Tololo supernova survey has discovered ~30 Type Ia supernovae out to z~0.1. Using BVI data for these objects and nearby SNe Ia, we have shown that there exists a significant dispersion in

On the relative frequencies of spectroscopically normal and peculiar type Ia supernovae

The main conclusion is that the observational sample of SNe Ia is strongly peaked at 'spectroscopically normal,' and that when arranged in the photometric sequence of Phillips (1993) S Ne Ia also form a spectroscopic sequence, and that peculiar S ne Ia are over-represented in the Phillips sample.

Type Ia supernovae in late type galaxies : reddening correction, scale height, and absolute maximum magnitude

We have collected and analyzed the color excess data for the best photometrically studied type Ia supernovae (SN Ia) which occurred in late type galaxies. From these data, a ratio of the B band to
