Denis Buczynski has reported that 12P is in outburst again. I’m imaging it at the moment and it is currently stable at around 10.3 in a 9 arcsec radius aperture. This morning it was 12.7. This is a good opportunity to pick up the comet visually in a moderate instrument. It is available in the evening and the morning from UK latitudes. Our latest lightcurve is attached.

So this shows the comet is getting brighter ? What about the tail of the comet, is it getting brighter/bigger as well ?
The comet is showing a fairly bright ion tail to the north but its length depends very much on sky conditions since it has a low surface brightness. The current total magnitude is around 6.6 so it should be approaching naked eye visibility at really dark sites. In a 9 arcsec radius the magnitude is around 10.4 and this is a bit above the trend for that aperture. It looks as if there have been a couple of small outbursts in the last week.

Larger than Mount Everest, apparently?
