The image was an HDR (5 shots). One of the goals was to catch the glow that the human eye sees but does not transfer well to the sensor. I missed the halo myself and now that it has been pointed out, I agree with the comments.
Thanks for the feedback; perhaps I'll have time this week to try stacking the many exposures taken instead of HDRing the one set; maybe I can get a positive effect from the time-lapse of the sun moving over the buildings.
