[vsnet-campaign-sn 463] classification of recent SNe



Dear SN watchers,

  The UCB team reports the classifications of some recent SNe in IAUC
7953.  All spectrum except for SN 2002ee are taken on Aug. 9 UT with
3-m reflector at Lick Observatory. 

SN 2002dr:

In [vsnet-obs 40349] (Jun 26):
>SN2002dr  20011213.2 <190:C  KAI
>SN2002dr  20020624.5  170:C  KAI
>SN2002dr  20020625.5  170:C  KAI
>
># The host galaxy of SN 2002dr is UGC 12214, a probable elliptical
># (S0?) galaxy interacting with another elliptical one.  SN is located
># at about 7" due south of the nucleus.  The expected maximum for
># typical SN Ia is mag about 16.6.

It turns out to be type Ia SN, about a half year after maximum.

SN 2002dx:

In [vsnet-campaign-sn 450] (Jul 15):
>SN2002dx  20011119.2  <195:C  KAI
>SN2002dx  20020708.5   188:C  KAI
>SN2002dx  20020709.5   189:C  KAI
>
># The host galaxy of SN 2002dx is UGC 12861, a faint spiral (Sab)
># galaxy.  The expected maximum for typical SN Ia is mag about 16.7,
># but it seems not to be of this type in the early phase.

It is also of type Ia, about 2 months after maximum. 

SN 2002ea:

In [vsnet-obs 40622] (Jul 23):
>SN2002ea  20020202.0  <205:C Puc
>SN2002ea  20020721.35  177C  Puc
>
># NGC 820, the host galaxy of SN 2002ea, is a spiral (Sb) galaxy.  The
># SN appears on quite near (1"E, 6"S) of the nucleus of NGC 820.  
># The expectec maximum for typical SN Ia is mag about 15.7.

It is of type IIn.

SN 2002eb:

In [vsnet-obs 40635] (Jul 25):
>SN2002eb  20020715.4  <190:C  KAI
>SN2002eb  20020722.4   185:C  KAI
>SN2002eb  20020723.4   182:C  KAI
>
># CGCG 473-011, the host galaxy of SN 2002eb, is a spiral (Sb) galaxy.
># The expected maximum for typical SN Ia is mag about 17.0.

It is of type Ia near maximum.  Thus it was caught about 2 weeks
before maximum. 

SN 2002eh:

In [vsnet-campaign-sn 459] (Aug 04):
>SN2002eh  20020201.2  <190:C  KAI
>SN2002eh  20020801.5   164:C  KAI
>SN2002eh  20020802.10  165C   Bol
>SN2002eh  20020803.4   164:C  KAI
>
># SN 2002eh appeared in the spiral (Sab) galaxy NGC 917.  The expected
># maximum for typical SN Ia is mag about 16.1.

It is of SN Ia, about a month after maximum light.

SN 2002ee:

In [vsnet-obs 40712] (Jul 31):
>SN2002ee  20020610.0  <205:C Puc
>SN2002ee  20020729.13  184C  Puc
>
># The host galaxy of SN 2002ee is NGC 5772, a tilted spiral (SA(r)b:)
># galaxy.  It is located at the outermost part of the northern disk.
># The expected maximum for typical SN Ia is mag about 15.8.

It is of type II SN (spectrum taken on Aug. 10, with the same
equipment as above).
