A technique has been developed which allows relatively accurate modelling of cometary gas production from nothing more than a visible light curve. Application to P/Halley suggests that the production rate of parent molecules will be about 2.6 x 10 to the 29th/second on March 10, 1986, for example. The uncertainties and intrinsic limitations in this approach are outlined. The theory is then extended to predictions of abundance of other gaseous species, and a photometric model of these gases is provided.Combined with the dust model of Divine (1981), preliminary predictions of the luminance of P/Halley, as seen in any direction from inside the coma or outside, can be provided for in the 3000-7000 A wavelength range.
