Hi Chris, unfortunately now that the moon is in the sky the comet would be a very difficult target. By the time the moon clears the comet will be too low. You can try for it if you want. I've attached a finder chart. Best observing time for Mackay is 5:15am very low in the north to the left of Capella. Over the next few days it will drop lower to the north each day. Don't worry if you miss it this August, it will be back in September.
Actually September / October will be great for comets. There's a bunch of bright ones all coming at the same time. 2014 E2 will be back, along with 2013 A1, 2012 K1 and 2013 V5. I'll be a busy little cometcatcher lol.
Probably the best pages to keep tabs on comets.
