dc.descriptionOur R-band data show that the optical light from Malin 1 corresponds well with the >2-arcmin extent of the galaxy's HI content and continues well beyond previously published V-band optical light radial profiles. Analysis of our image yields improved understanding of the galaxy's properties. We measure ellipticity of 0.20 +/- 0.03, implying inclination of 38 +/- 3 degrees, and we trace the radial profile to 77 arcsec. A single dusty spiral arm is also weakly discernable, and is consistent with the rotation direction of the HI and spiral structure of the inner disk. Possible scenarios for the origin of the spiral structure are discussed.
