We propose an imaging observation of the smallest known gravitational lensed system 0218+357. This system is unique in having a well determined time delay between the two lensed images and a simple lensing geometry. The redshift of the lensing galaxy is known although the redshift of the lensed object has yet to be determined. Almost all the ingredients necessary for an accurate determination of the Hubble Constant are therefore available for this object. To achieve this it is important to eliminate as many sources of uncertainty as possible; a major source of error can be removed by better constraints on the position and orientation of the lensing galaxy relative to the lensed images. This is impossible to do from the ground due to the 0.335 arcsec separation of the lensed images and consequent difficulty in disentangling the emission from the images from that of the lensing galaxy. We propose a brief HST imaging observation which will allow us to do this.
