Arrrgh! I fear I’m at least partly responsible for this. Some of the article looks like a mangled version of what’s on my website. My website says that the comet rises at 21:15 BST. I assume the summer student who wrote this article cut and pasted the rising time as the best time to see the comet.
A couple of weeks ago I changed the algorithm used by my website to decide when to list comet apparitions as news events. This resulted in some very bad predictions, which I commented on in a previous forum post. Martin and Nick convinced me I needed to fix this, but I haven’t had time to get it changed yet.
I really need to get on with it… sigh…
