    Another outburst? I am imaging now and it is much brighter than I expected. Worth having a look visually too.

    See the screenshot.

    Looking quite spectacular as a big fuzzball moving through the star field.

    Hello David,

    Yes indeed it’s a new outburst…well spotted.

    Here’s my image taken last night 2018 July 14th at 2358UT.

    The coma looks like it has expanded significantly since last night. Still bright and quite something.

    Indeed. It is a really nice comet tonight. Here is my image. I get an integrated magnitude of 8.49 and a coma diameter of almost 6 arcmin.

    Nick.

    The comet continues to brighten. There is a news item here which explains more.

    Not looking as impressive this evening (20 Jul / 2300 BST). Fingers crossed that this isn’t the beginning of the end….

    Transparency poor, but managed 10 frames when it seemed to clear slightly. 10 x 10s

    It was cloudy here last night so no data from me but it does appear to be fading if you look at the latest estimates here. My news article on the front page was clearly the kiss of death! Michael Jäger reports no sign of the tail last night in deep images obtained on July 21.05. David Levy’s famous quote about comets: “Comets are like cats, they have tails and do what they want” is quite appropriate I think. We just need to keep observing and see what happens next.

    It continues to fade. I made it 9.4 earlier today. It is still there though and there are no apparent signs of disruption so we might get another outburst soon. Keep an eye on this object at every possible opportunity.

    The coma profile for the past few nights shows that it is much more diffuse this morning and I think we are witnessing its final days.
