Fantastic. It may be in a sufficiently faint region of the galaxy to be visually detectable even now. I will, however, wait for moonless nights in April to try to see it together with the structure in the galaxy.

EDIT: Comparing the SN photos with my composite sketch from last year, the SN should be on the periphery of the halo visible in a range of magnifications:

Plan on trying Thursday. The weather is predicted to be possible as well as the Moon will be out of the way long enough for it to get dark.

It's right in the dust lane of the galaxy so will be reddened and probably tougher than it looks. Think I'll setup the 20".

Is it possible SN20213AM is heavily obscured by interstellar dust, and therefore looks dimmer than it actually is? Or will it take a period of weeks for it to become bright enough to see in smaller telescopes and or light polluted areas?

It's possible as my color image does show the SN as a reddish color. As for your second question only time will tell.

I have also imaged it in both Luminosity and Red. The supernova does seem to be brighter in Red. I estimated it as 16.7 with the luminosity filter and 16.2 with the Red filter. I was using a SBIG STF-8300m camera with Baader filters. Bottom line is this remains a very tough target visually. Images are here:

Yeah, if there is any brightening to this point, it is absolutely minimal and fading is a distinct possibility. This one isn't acting like it is "supposed" to. Apparently someone forgot to give it the memo.

Yep, It was mag. 15.6 on 3/21 and mag. 16.2 on 3/22, now you are saying it is in the mid 16th mag. range. I do not think it will become visible in any of my telescopes. I hope that these are wrong and it brightens up enough to be seen.

That sound correct. On Friday evening I managed a visual observation using my 20". It was not easy. I was using a 5mm Baader Genuine Ortho for 365X and an observing hood. I could hold it about 75% of the time. Not only is it in the dust lane but it is also right beside a faint glow of the galaxy that is visible within that dust lane. It took awhile to determine that there was a dot next to the glow. It was kind of confusing and all while hand tracking with the microscope FOV of the ortho.

A darker sky might help as while the Moon hadn't risen yet its almost full phase was lingering just below the horizon. I think I'll have a quick look again this evening but then move on.

Excellent observation. I am hoping to try visually myself later this week with my 16". I have seen supernovae of this magnitude, but the position of this one and the sheer brightness of the Messier probably spell failure. Regardless, I wanted to carefully reobserve this galaxy and make a better sketch of it, so perhaps over the hours that this may take the SN might show.

Great observation on a difficult object. My shot from tonight below - the SN mag seems essentially constant since discovery

So... A type II-P discovered after its rise and on the plateau? Then we have plenty of time to keep trying for it visually but it will not get any brighter.

I was unsuccessful last night in detecting SN 2013am using the ASH 17" f/15 classical Cassegrain at magnifications as high as 462x. I didn't really expect to be able to see it, so I wasn't terribly disappointed.

That's a shame Dave - got another shot last night and SN unchanged. I'm beginning to suspect it's not going to get brighter as it should have by now

That's discouraging for visual, gentlemen. Well, tonight is the best chance for good transparency in a clear moonless sky for April here, but the seeing is going to be atrocious, plus the wind (vibrations). I plan on observing M65 anyway, but seeing this particular SN seems out of question in these conditions...

Here is the sketch I made last night (16", blue zone). The SN was invisible. It was supposed to be just N or on the N edge of the inner separated star cloud on the S end of the galaxy. However, even 450x with an Abbe II orthoscopic could not bring out the star or subdue the star cloud appreciably. I did not go higher due to seeing, which started out bad in the evening and was only approaching average before moonrise.

EDIT: I oriented the sketch conventionally (N up, W right).

No, I can not see it visually but this picture was taken with my CPC1100 SCT Celestron ALT / AZ mount from south Sweden in April 1 at 23:30. The camera is my new Bright Star MAMMUT color CCD IMAGER with focal reducer around f / 3. A simple image with a exposure time of 40 seconds and no image processing (no flat, dark

IVM, excellent sketch! I tried last night but no luck. I thought it would brighten but alas, its not. Well, there will be more I'm sure in other Messier galaxies that will be visible. Just read a study about identifying RSG and WR stars in M101. There will be others in M101 over time, probably in my life time.

Two fellow CAS members and I observed SN 2013am on Friday night from one of the best "local" dark sites. I caught fleeting glimpses of it through a 22" SDM Dob at high magnification. The owner of a 17.5" TeleKit Dob with a Zambuto mirror said he was able to see it about 60% of the time through his scope.

Some other CAS members viewed the supernova from a different site that night.

I did end up trying Friday night. I was using my 20" f/5. Transparency was OK but not great. Like someone else said earlier, galaxies just weren't popping. I was able to see the star that is near the nucleus of M65 but the SN was not to be seen. Still, it was worth the visit and I enjoyed the trio. This was one of the first set of galaxies I learned to find way way back in the day so a visit is always brings back a little bit of nostalgia.

On Friday night the seeing was supposed to be bad again but I noticed that from time to time I was actually able to see Airy disks. I was on M66 with my 16" and moved over to M65 to try for the SN at 225, 300, and 450x with ZAOIIs. Again no SN did I see, and not even the star W of the core which is comparable.

Saturday night with my 20" f 4.5 using Meade 14mm & 8.8mm 4000(163X & 260X) with average seeing, I spent ~ 20 minutes observing M 65. Like others, I could make out several superimposed stars on the galaxy but could not pull out the SN. Due to the seeing, 16 mag was the limit that night. It was fun trying anyway.

I also struck out on this one tonight; seeing was a bit soft and I don't think I was getting much deeper than mag 15 on point sources. There were two moments where I had a momentary flicker in averted vision at about 400X, but I don't put any credence in those. Fortunately, I had better luck with the SN in ngc 2554.

Thanks Dave - your pic ~44hrs before mine from last night timed Apr 11 @ 21.01UT and I'm sure the SN has faded to ~m17.1 from my last pic of Apr 5 some 6 days ago - both in image below

Tonight's shot Apr 15 under very poor transparencey eg NELM 3.4. I suspect the SN had dropped below visual
