CATACLYSMIC VARIABLE STAR IN TAURUS
H. Yamaoka, Japan, reports on CBET 1463 the discovery by K. Itagaki, 
Japan  of a variable star (mag 14.1) on an unfiltered (red) survey CCD 
image taken with a 0.21-m f/3 reflector
around Aug. 7.7 UT.  The position is:
RA 4h 06m 59.78s DEC +0 52' 44.3" (2000), and it was fainter than mag 
17.0 on Itagaki's survey image taken on 2007 Oct 13.

H. Kaneda (Sapporo, Japan) notes that an x-ray source (1RXS
J040700.2+005247) is located within 7" of the reported position, and the 
variable should be identical with a USNO-B1.0 catalogued star (B1 mag 
18.4, R1 mag 17.5) whose position end figures are 59s.82, 44".3.

Following an appeal by the Central Bureau, C. Jacques and
E. Pimentel, Brazil write that they obtained a 60-s unfiltered CCD image 
on Aug. 9.46 remotely using a 0.25-m f/3.4 reflector near Mayhill, 
finding position end figures 59s.82, 44".0 and mag 13.7. There is also 
an ASAS image of Aug 4.42UT showing it at V=13.5.

Photometry by G. Bolt on Aug. 8 show the variable to display clear 
superhumps with an amplitude of 0.2 mag and period around
0.06 day, which indicate that the object is an SU UMa-type dwarf nova.

SUPERNOVA 2008eo IN UGC 442
A spectrum of this object at Lick on Aug. 8 (supernova found by Tom 
Boles and reported on E-Circular 2470) shows it to be a normal type-Ia 
then near maximum brightness (CBET 1465).
Regular photometry by Guy Hurst, Basingstoke using the Bradford Robotic 
Telescope shows the object reached peak brightness at 15.3C on 2008 
August 14.

SUPERNOVA 2008ep IN UGC 826
A spectrum at Lick on Aug 8 of this supernova found by Tom Boles also 
shows it to be a normal type-Ia supernova then about a week before 
maximum brightness. (CBET 1465)
BRT Photometry by Hurst shows this object discovered at magnitude 18.1 
on August 4 brightened to 15.9C by August 27.

SUPERNOVA 2008en IN UGC 564
A Lick spectrum of August 8 of this discovery by Tom Boles shows it to 
be a type-IIn supernova with broad emission lines of the hydrogen Balmer 
series and He I. (CBET 1465)


NOTE: E2477 has been dispatched via bt internet as a trial run for when

glitches that may result from this test.
