Dwarf Spheroidal Galaxy Cetus Dwarf, type dE4,
Discovery of the Cetus Dwarf was made by
Alan Whiting, George Hau and Mike Irwin by visual inspection of photographic
plates from the UK Schmidt Telescope survey, microdensiometry at the Royal
Greenwich Observatory, and deep CCD photography with the 1.5-meter telescope
at CTIO and the 2.5-meter Isaac Newton Telescope, and announced on June 4, 1999.
This very low surface brightness galaxy was found to be a Local Group member
because red giant stars could be seen.

2.5-m INT image of the Cetus dwarf,
combined V-band image with a total exposure of 1800 s taken using the Wide
Field Camera. The obvious visible stars in the dwarf galaxy are all red
giants. The area shown is approximately 11 × 11 arcminutes corresponding to
one-half of the central CCD of the four WFC CCDs.
