[vsnet-alert 7258] SN 2002bu in NGC 4242



Dear SN watchers,

  A nearby (nearer than the Virgo cluster) SN is discovered at mag 
15.5.  The expected maximum for the typical SN Ia is mag about 11.7.  

  SN 2002bu is discovered on Mar. 28.26 UT at Puckett Observatory.
The position of the SN is: R.A. = 12h17m37s.18, Decl. =
+45o38'47".4 (2000.0), which is about 73" east and 98" north
of the center of the somewhat irregular-shaped (SAB(s)dm) galaxy
NGC 4242.  Because of the large angular diameter (5'.0 x 3'.8), 
there are many foregroud stars superimposed on this galaxy.  And, 
H II regions and large clusters of stars are also populous.  The 
identification of SN should be done carefully.

  NGC 4242 is a member of a nearby group of galaxy called 
"Canes Venatici II cloud", whose mean redshift is about 750 km/s.
The expected maximum for the typical SN Ia is mag about 11.7, 
and even if it is of type-II, it can become brighter than mag 14. 
The spectroscopic confirmation and the followup photometries are 
surely urged.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
