Comet C/2018 N2 (ASASSN)


Recommended Posts

Comet C/2018 N2 (ASASSN) was discovered a year ago and will reach perihelion next month of November, but will not go much inside the Solar System and will not shine more higher than magnitude 11. In this image taken on July 12, 2019 the comet is at magnitude 13, have not very gassy appearance but is already showing a nice dust tail. The brightest star is at magnitude 7 highlighting also in upper part the spiral galaxy NGC 1024, the bigest, although at least fifty small galaxies can be seen in this field with only 37 square arcminutes.

Comet C/2018 N2 (ASASSN) imaged on August 3, 2019, with a visual magnitude near 13 the comet shows its curved dust tail with an angular lenght of some 7 arcminutes. The brightest star into field is Omicron Arietis with a brightnes of magnitude 6.

Comet C/2018 N2 (ASASSN) image on August 10, 2019 with more resolution. With a slight increase of brightness until magnitude 12.5 its appearance barely has changed  with its 1 arcminute coma which contains a sharp central condensation and its curved dust tail with more that 5 arcminutes lenght.

On September 7, 2019 the comets C/2018 N2 (ASASSN) and 260P/McNaught crossed in the sky on this field full of small galaxies in Aries constellation. Its minimal angular separation was only 10 arcminutes, although only due our perspective from Earth, as both comets were far away from each other; at bottom comet 260P/McNaught to 0.6 A.U. from us and at upper comet C/2018 N2 (ASASSN) to 2.6 A.U., two times the distance from Earth to Sun separates them.

Looks like you also captured an asteroid in that frame, just above the fine edge-on on the upper right of the comet. (?)

Thanks to all for your comments :)

Yes, this was something inherent to sensor. Perhaps a ghost because of the bright star, or remanent from previous images (this camera would need a flush RBI). There are other similar on image and all aligned to sensor.

 

Attached a new version of conjuntion, in monochrome:

Conjunction of comets C/2018 N2 (ASASSN) and 260P/McNaught on September 7, 2019. Photographed with a more sensitive camera than my color image taken at same day, this monochromatic version stand out dust tails details. Highlights inside tail of 260P (at down) is a bright central spine, due we are crossing these days the orbital plane of this comet and we see sideway the most of dust which are always concentrated in that plane.

Comet C/2018 N2 (ASASSN) on October 11, 2019 near its maximum brightness with magnitude 11 shows a coma of 1.25' angular size  with a dust tail 10' lenght. The bright blue star is HD 9298 with magnitude 6.4 into Triangulum constellation.

Comet C/2018 N2 (ASASSN) imaged on November 29, 2019 through IAC-80 telescope in Teide Observatory (IAC). With a coma 1 arcminute diameter (110 000 km absolut size) and a dust tail with 6.5 arcminutes lenght. Even though the most remarkable is the high detail inside coma of a comet with magnitude 11.5, only possible by means of a telescope like this.
