The pros have some initial photometry and its seems the red magnitude is 14.3 so that's a lot more promising. We have been sent some Hubble Deep field images around the PSN site and there maybe several candidates for the progenitor (star that exploded). We have been inundated with emails from professional astronomers all over the world. Amazing. Yes lots of color images folks. Go back over any recent images as we know its wasn't there on the 3rd February so getting a timeline would be valuable.
