More on the new VISUAL discovery of C/2018 V1 (Machholz-Fujikawa-Iwamoto). Note that only Don Machholz of the three discoverers found it visually. The others imaged it.

I saw it early is morning in my 10" Dob. It was surprisingly bright and easy to locate. Congrats to Mr Machholz for keeping the possibility of a visual comet discovery alive.

I uploaded the information on Stellarium 18.2 last night. Its definitely positioned well for an easy find.

I was able to observe this comet this very morning, 4:15 UTC.

The coma diameter was big in my bino 125mm 40x.  My difficult estimated magn is between +7 and +8. The local mist before sunlight was not cooperative.

A sketch will come soon in the sketch forum 

Clear sky to you all

On the morning of 11/17, I was able to detect C/2018 V1 as a faint, fuzzy star in my 8x42 binoculars. I brought out my 10" Dob on 11/18. The comet was easy to find, just about 30' from Zeta Virginis. It looked like an unresolved globular cluster, round and strongly condensed with a large bright core and fairly bright halo/outer coma. I didn't see a stellar pseudonucleus. The outer coma had a faint extension to the NW, likely the beginning of the tail. The coma looked bright silvery to me; I didn't detect blue color, and I didn't feel like my Orion UltraBlock filter that sometimes helps with gas-rich comets improved the view.

Any rough predictions (as far as comet "predictions" go ! ) as to expected future brightness?

I finally “spotted” it this morning. Had about 15mins between the nearly full moon setting and twilight beginning. Couldn’t see it in either the 50mm finder, or 63mm and 80mm binoculars. Star hopped with a 10” Dob. Faint, but visible within a triangular field of 9th mag. stars at 85X. Sadly, weather has not been cooperative here in the Northeast. Between the full to waning Moon in the near future and the reality of poor weather, that’s probably it. Clear and steady skies......

Nice catch nonetheless.  I tried three times last week (90T, MK 66, 12x60 binoculars) and struck out.  Probably too late now to see it for the time being as it is heading into the rising sun now.

Perhaps we will be lucky and it will brighten after it swings around the Sun!

Any info on if the comet is currently observable?

 

Aerith.net says it should be observable in the evening Dec 5-15?

Perihelion today, but didn't manage to spot it in 20 x 80 binos. Reports say it has dropped to around mag 10 and with a continuous low altitude will be a challenge to see it at all before it sinks into the S Hemisphere.

I'm waiting for any clear evening to view this in the west at sunset. I have a site I can go to close to home with flat open horizons to the west for observing this with my 100mm APM Binoculars.

The cloudy weather is driving me nuts. I've been able to see 38/P and 46/P, and a few months ago I had some fun observing 21/P, but I need some visuals on Comet C/2018 V1.

I'm on red alert, checking the weather, clear sky clock, everything I need to, to catch this at sunset.

 

Keeping my fingers crossed for some clear skies soon.

I managed to view C/2018V1 (Machholz-Fujikawa-Iwamoto) with my 25x100 binoculars on December 5.68 UT. I estimated it as magnitude 9.4, coma diameter 4' and DC=4. It was only 6° over the W horizon and elongation 23°. This might have been the first post-perihelion sighting and as an evening object?  I saw the comet from Sweden, latitude 60°.

I also observed this comet today (Dec 5.73 UT) using my 32×125 pair of binoculars. I estimated it as m1=10: mag, Dia=8', DC=3. The

comet was 7.7° above the horizon. I live at 51N, SQM-L at zenith was 21.0 MSA.

Had a fairly unobstructed horizon to the West last night.

Has SS open,  my "real" compass , my iPhone compass. Wanted to take a try at 2018/V1

 

Using 4.5" Bushnell , sweeping between lambda Aql and Saturn , bumped into M11 a few times. Was not dark quite yet soon to get too low to view.

 

Could have seen a fuzzy star, an afterthought should have bumped up the power to confirm is was not a cluster in the area. Not a confirmed sighting , just suspected. 

 

This from a class 3 site at

SQM 21.76

This comet seems to be a tough find. Its looking like I may have a short at searching for it tonight. I have to leave work early, run and get my 100mm binoculars, and get out to my site with the flat western horizon's.

Based on the weather conditions, I just have tonight and tomorrow night, then its cloudy till after Christmas!
