C/2018 V1 (Machholz-Fujikawa-Iwamoto)

Postby Aratus » Wed Nov 14, 2018 6:12 pm

It is all a bit uncertain at the moment, but a new comet has been detected near the sun.
Comet Machholz-Fujikawa-Iwamoto has been coming towards the sun at an acute angle which made it impossible for us to see it until now. It is a morning object in Virgo at the moment, but I've not seen any accurate orbital elements yet. It will swing around the sun, and appear in the evening sky at some point, but I don't know if it will be well placed or not.
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.

That's useful. I've been running some of the orbital elements, and it will be best to see it in the next few weeks in the morning. When it rounds the sun, it will be visible in the evening sky, but very low down, and getting dim very quickly.

Here's a piece from Comet Watch:

Future magnitude is still an unknown. Could become naked eye visibility.

I estimate most people in the UK have at least 10 days to see it in the morning. It is dropping quite quickly, and you need to see it at a reasonable altitude in an increasingly bright sky. It is getting brighter by all accounts though, which will help. South East and East are not good directions for my location.

Stangely, it willalso appear at low, but useable altitudes in the evening sky from about 28th Nov for a little while. By this time Comet Wirtanen should be a fine sight in the same early evening sky.
