Thanks for posting the comet positions Barry. Unfortunately Bradfield is fading fast I hear
Not too fast, I hope. Barry's chart shows it at 6.4 mag but a report from Norway estimated it at 5.0 on 4/24 and a photo and report posted on spaceweather.com on 4/27 said it was naked eye from Colorado skies (fantastic photo, BTW).
I guess we just have to go out and look.

I posted this observation in the Planetery Forum but I know there is some interest here, too.
I saw C/2004 F4 (Bradfield) this morning 4/28 for the first time(!) I estimate transparency was 5-6/6 up high but only 3/6 near the horizon. Temperature was 30deg F with a moderate wind. I was using 10x50 binocs.
I have a mountain blocking the first 10-12 deg of horizon. Bradfield rose above the mountain at 0900UT (5:00AM EDT) and was easy to spot through the binocs. It was ~5-6deg SE of beta Andromedae with a fairly bright head (~mag 3.5-4.0) and a long graceful tail that streamed out to the west at least 7deg in the 10x view with a hint of another 7deg fading away. By 0925UT it was almost lost in the skyglow through the binocs.
Bradfield is everyone's idea of what a comet should look like--see it if you can. I'm going to try a sketch tomorrow AM; conditions were too cold and windy today. I was happy just to find and observe it.
I spotted C/2002 T7 (LINEAR) as well ~5deg east of the circlet in Pisces, but it is underwhelming compared to Bradfield--very faint with no discernable tail. I hope to look harder at it tomorrow.
BTW, I checked the FOV of my 10x50's using the values Barry gave for the lid on the teapot in Sag. The binocs say 7.5 deg FOV on them but the real deal is 6 deg.

Exactly Michael. As a philosophy, regardless if I do or don't expect to find a certain celestial object(s), the act of searching & learning is an equal (if not greater) reward.
The current pic on spaceweather.com is of Bradfield taken from Cape Cod. That's what I hope to see!!
