Title

Really poor conditions this morning with the Moon and significant haze combining to make the sky very bright. The sky brightness in the comet's field was 15.4 mags per square arcsec! I got a total magnitude of 5.7 but this is bound to be an underestimate given the conditions were so poor. Despite the rubbish conditions it still shows a reasonable tail. Hopefully we'll get some clear, transparent skies over the next couple of weeks when the Moon is gone and it is in the evening sky.
