Here's a rough composite showing the growth of Lovejoy over the last 4 days,
using some images kindly lent to me as I've only had one fine morning to observe
it since it hit dark skies again. The various images were resized to the same
scale. Don't place too much credence in the actual degree length stated as there
are lots of variables that determine how much will be showing in any particular
image. For this morning, the 30-degree tail length is based on several
photographs that appear to show very faint extensions out to that length.

Anyway, the massive expansion is pretty clear. Hoping to get another great view
of this 'megacomet' in the morning.
