U SCORPII
B. E. Schaefer, Louisiana State University, advises that a
previously unknown eruption of the recurrent nova U Scorpii was 
discovered on Harvard College Observatory archival photographs of 1917 
March 6 at B=9.1. With eruptions of U Sco having occurred in 1906, 1917, 
1936, 1945, 1969, 1979, 1987, and 1999, Schaefer notes that U Sco has a 
fairly constant recurrence cycle of 8-12 yr -- with about 25 percent of 
the outbursts being missed due to proximity to the sun (including 
potential missed outbursts around 1926 and 1957) -- adding that the next 
U Sco eruption should occur sometime during 2007-2011. (IAUC 8279)

SUPERNOVA 2004K IN ESO 579-G22
A further LOSS supernova discovery has been reported on IAUC 8273, this 
time in the galaxy ESO 579-G22.

The magnitude 17.2 object was recorded on KAIT images of 2004 Jan 19.6UT 
at:
RA 14h 23m 39.85s DEC -19 26'50.0" (2000), 15.5"W, 11.8"S of the parent 
galaxy's nucleus.

SUPERNOVA 2004L IN MCG +03-27-38
Yet another LOSS discovery has been reported on IAUC 8274. The magnitude 
16.9 object was recorded on 2004 Jan 21.4UT in the galaxy MCG +03-27-38 
at:
RA 10h 27m 04.11s DEC +16 01' 07.3" (J2000), 2.5"E, 3.1"N of the
nucleus.

SUPERNOVAE 2004M, 2004N, AND 2004O
These three supernovae have been found with the OGLE/NOOS transient 
system and reported on IAUC 8276:
SN      2004 UT       R.A.  (2000.0)  Decl.   Mag.     Offset
2004M   Jan.  6.1    0 35 59.26  -74 48 02.0  19.5   10.7"W, 3.1"S
2004N   Jan. 21.2    5 35 20.37  -69 27 18.3  18.0   4.4" N
2004O   Jan. 24.2    4 43 44.82  -70 28 33.8  20.0   3.6" W, 1.6"N

SUPERNOVA 2004P IN UGC 8561
Another LOSS supernova discovery has been made, this time in UGC 8561 
when an object of magnitude 16.3 was recorded on Jan 23.5UT:
RA 13h 34m 57.76s DEC +34 02'33.7" (2000) 6.0"E, 4.5"S of the nucleus 
according to IAUC 8277.

SUPERNOVA 2004Q IN ESO 507-G11
Another LOSS supernova discovery has been made, this time in ESO 507-G11 
according to IAUC 8281. The object was first detected on Jan 30.5UT at 
magnitude 18.4 and is located at:
RA 12h 47m 40.11s DEC -26 12'23.3" (2000), 2.5"W, 24.1"S of the nucleus.

SUPERNOVAE 2004R IN ANONYMOUS GALAXY
This object was detected with the Hubble Space Telescope at:
RA 03h 32m 31.30s DEC -27 46'13.6" (2000), 0.13"W, 0.10"S of the centre 
of the host galaxy. Z-band magnitude estimate on Jan 10.4UT was 27.2. 
(IAUC 8281).

SUPERNOVA 2004S IN MCG -05-16-21
R. Martin, Perth Observatory, has reported discovery of a magnitude 16 
supernova on CCD images of Feb. 3.54UT with the 0.61-m Perth/Lowell 
Automated Telescope. It is located at:
RA 06h 45m 43.50s DEC -31 13' 52.5" (2000), 47.2"W, 2.5"S of the nucleus 
of MCG -05-16-21 according to IAUC 8282.
