SUPERNOVA 2008eo IN UGC 442
On 2008 August 3, Tom Boles, Coddenham, England, reported to us the 
discovery of an apparent supernova (mag 16.0) on an unfiltered CCD image 
taken on Aug 03.076 with a 0.35-m reflector during searches for the UK 
Nova/Supernova Patrol.

The object is at:
RA 00h 41m 52.04s DEC +32 59' 25.1" (2000), which is approximately 2.4"E 
and 0.9"S of the centre of the host galaxy, UGC 442. Nothing is present 
at this position on Tom's images from 2007 Sept 14 and Oct 17 (limiting 
mag 19.5) nor on the Digitised Sky Survey Plates from 1990-10-24 
(limiting red mag 20.5), and 1987-08-21 (limiting blue mag 21.0).

Confirmation was obtained by Tom on Aug 4.013UT at magnitude 15.9.

The object was designated supernova 2008eo on CBET 1459. Congratulations 
to Tom on the discovery of his 115th supernova.

COMET 199P/SHOEMAKER
Mark Kidger (Herschel Science Centre, European Space Agency, European 
Space Astronomy Centre, Madrid) reports the detection of a large 
outburst of 199P/Shoemaker by Gustavo Muler (MPC J47, Lanzarote, Spain), 
confirmed by numerous observers from the "Observadores_cometas" Group, 
including Ramon Naves and Montse Campas (MPC 213, Barcelona, Spain), 
Jose Maria Ruiz (MPC J40, Malaga, Spain) and Josep Lluis Salto (MPC A02, 
Ager, Catalonia, Spain).

Representative magnitudes (10 arcsecon square aparture) are:
2008 Jun 24.92, 18.10 (Muler)
2008 Jul 07.89, 17.81 (Muler)
2008 Jul 14.94, 17.49 (Muler)
2008 Aug 03.86, 14.7  (Muler)
2008 Aug 03.92, 14.46 (Naves and Campas)
2008 Aug 03.93, 14.58 (Salto)

Almost all of the light is, at present, confined within a 20 arcsecond 
aperture. VRI photometry by Naves and Campas finds (R-I)=-0.05, 
(V-R)=+0.36 suggesting colours bluer than solar with a significant 
component of gas emission despite the relatively large heliocentric 
distance of r=3.41AU.
