Comet located only 8 deg over the horizon when the telescope in Chile started imaging. Dust tail at PA 354 deg is clearly visible, while another tail at PA ~180 deg is very faint and nearly coincides with the PsAng direction (178 deg). This tail is barely visible on negative image. As Earth is passing through a comet's orbital plane, probably what we see is the gas tail and a dust trail at the same time.
Unfortunately, I found comet saturated so had to skip a photometry.
