Comet C/2018 W2 (Africano)

[PepeChambo]

Comet C/2018 W2 (Africano) is the next comet relatively bright which could reach visual magnitude near 8.5 this September. In this image taken on July 7, 2019 has a brightness in magnitude 12 approximately, and a greenish coma with an angular size of 1.5' and a strong condensation.

Comet C/2018 W2 (Africano) on July 9th 2019, showing a coma with 3' of angular size. This comet seems having more activity since some days ago and could be observable with binoculars on September.

Nicely captured Jose, let's hope it puts on a show.

A comet with binoculars could be a luxury nowadays.
Thanks Dave.

Very nice, Thanks for sharing these!

Comet C/2018 W2 (Africano) imaged on August 9, 2019 when was passing near star open cluster IC 361, located in Camelopardalis and containing about 60 stars between magnitudes 11 and 18. In this image the external coma appears very faint and with an angular size of only 2 arcminutes, elongated at anti-solar direction (toward west). Visual observations on these date reported the comet with a magnitude arond 11.

Thank you for sharing

Well done Jose, I managed to get my first pic of it in the early hours of the 8/8/19  with my ODK 12. 300s unguided @ iso1600 but it is very very faint indeed and not a lot to see at the moment. Will be keeping an eye on it though and taking more pics .

This comet has a low condensation and is hard to observe. Next month will be more bright and I think a bit more easy.

It's getting to a reasonable height here now so will try for it when the Moon goes away and it stops raining.

Thanks for sharing your image Jose. Will try to spot it when the moon fades.

Hi Bob, we also have C/2017 T2 PanSTARRS creeping ever higher up the sky during September / October.

Hi Dave, thanks for the heads up, it looks as though we might have some comet imaging to do.

Nice images. I do find these green comets fascinating.

A lovely image Jose, showing it well.

Good stuff Jose. been working on a time lapse of it but it's slow going

Thanks for comments
This was some days after:

Comet C/2018 W2 (Africano) imaged on September 5, 2019, with a brightness around magnitude 9.5 its coma reaches an angular size near 5 arminutes, although is extremely faint; only carefully inspecting the image can be seen hor far goes the green luminescence of diatomic carbon.

Lovely images Jose, I'm still working through my 100 odd frame animation

On September 12, 2019, a week after having passed perihelion, comet C/2018 W2 (Africano) continued approaching to Earth with its faint greenish coma increasing in angular size to 8 arcminutes. Its bightness was then in magnitude 9.5.

Comet C/2018 W2 (Africano) imaged on September 21, 2019 when reached its maximum brightness near magnitude 8.5 coinciding with approaching to 0.5 AU from Earth. Shows a diffuse greenish coma with an angular size 12 arcminutes. A faint dust tail extends toward north (to upper) observable because these days we are crossing the orbital plane of comet. In this field slightly smaller that one degree between Pisces and Andromeda constellations highlighs NGC 266, a barred spiral galaxy.

Another great image Jose, managed to beat my animation into some sort of shape.

Great image!

Wide field image of comet C/2019 W2 (Africano) taken on September 27, 2019, are 4 x 2.5 degrees centered in a side of Pegasus square. With a brightness in magnitude 9 comet shows a nice green coma with 12 arcminutes and a slightly curved dust tail with half degree lenght.

Excellent image Jose, I've captured it a few times but no tail visible in my images.
