[vsnet-alert 7570] classifications of recent SNe (IAUC 8007): SN II 2002hh



Dear SN watchers,

  IAUC 8007 informed the classifications of several recent SNe.

SN 2002hf:
In [vsnet-obs 42108] (Oct. 31):
>SN2002hf  20021002.3  <185:C  KAI
>SN2002hf  20021022.3  <170:C  KAI
>SN2002hf  20021029.3   165:C  KAI
>SN2002hf  20021030.3   165:C  KAI
>
># MCG -05-3-20 = ESO 411-G34, a host galaxy of SN 2002hf (0:57:47.74,
># -27:30:21.5 (J2000.0), offset = 10"E, 16"S), is a spiral (SAB(r)c:)
># galaxy in foreground of a distant cluster.  The expected maximum for
># typical SN Ia is mag about 16.1.

  Spectrum taken with Lick 3-m telescope by The UCB team on Nov. 2
shows that is it of type Ic within a week past maximum.

SN 2002hg:
In [vsnet-obs 42108] (Oct. 31):
>SN2002hg  20020116.0   <185C  Bol
>SN2002hg  20021028.219  170C  Bol
>SN2002hg  20021030.54   167R  SCH
>
># NGC 3306, a host galaxy of SN 2002hg (10:37:10.60, +12:39:13.2
># (J2000.0), offset = 6"E, 4"N), is a spiral? (SB(s)m?) galaxy.  SN is
># superimposed on the bright bulge region.  The expected maximum for
># typical unreddened SN Ia is mag about 14.6, but it is unlikely
># because it has remained almost the same magnitude (and >2mag below)
># for 2 days.

  The UCB team (with Keck II 10-m on Nov. 1.6) and the ESO team (with
Calar Alto 2.2-m on Nov. 2.22) report that SN 2002hg is a typical type
II SN after maximum light.

SN 2002hh:
In [vsnet-alert 7569] (Nov. 2):
>  IAUC 8005 informed the discovery of (apparent) supernova in NGC
>6946, which had produced at least 6 SNe (1917A, 1939C, 1948B, 1968D,
>1969P, and 1980K) in the last century.  The brighetst one of these six
>was SN IIL 1980K, whose maximum was B=11.6.
>
>  It was discovered by the KAIT team on Oct. 31.1 UT (mag about 16.5)
>and confirmed on Nov. 2.1 (mag about 16.3).  The position of the new
>object is R.A. = 20h34m44s.29, Decl. = +60o07'19".0 (J2000.0), which
>is about 61" west and 114" south of the nucleus of a face-on open
>spiral (SAB(rs)cd) galaxy NGC 6946.  It was below mag about 19.0 on
>Oct. 26.1.  It should defenetely be in the rising phase.  Further
>observation is strongly encouraged.

  Spectra taken by The UCB team (same as SN 2002hf) reveals that SN
2002hh is a very young and highly reddened type II SN.  

  Note that there is a bright (GSCmag 12.7) foreground star about 10"
west of the SN.  The discovery image can be seen at:
