Dear SN watchers,

  The LOSS KAIT term has discovered a new supernova.  According to
IAUC 7215, an apparent supernova, named as 1999da, was found on July
5.4 UT (mag 17.0), and confirmed on the previous image taken on July
2.4 UT (mag 17.6).  The reported magnitudes indicate that it is on the
rising phase.  The location of new star is: R.A. = 17h35m22s.96, Decl.
= +60o48'49".3 (2000.0), which is about 71" west and 1" north from the
nucleus of NGC 6411.  This position is well outside of the main body
of the host, and because of rather low galactic latitude (b \sim 33),
there are some confusing field stars.  The discovery image is provided
at: http://astro.harvard.edu/~bait/sn99da.html , which is very useful
for identification.

  NGC 6411 is an elliptical one, then it is expected that SN 1999da is
of type Ia and is not so absorbed.  From the recession velocity of the
host, it can be reach around 15 mag at its maximum.  Followup
magnitude estimates are encouraged, as well as the spectroscopic
confirmation. 

  On the other hand, IAUC 7216 tells that SN 1999cw (vsnet-alert 3168:
http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-alert/msg03168.html)
is of type Ia which resembles with peculiarly bright SN Ia 1991T
around maximum.  Followup observations are surely encouraged.  Also,
in the same circular, SN 1999cz (vsnet-alert 3186: 
http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Mail/vsnet-alert/msg03186.html)
is reported as being of type Ic a few after maximum and highly
reddened probably due to the dust lane. 

Sincerely Yours,
