I certainly wouldn't mind if it did.

I imaged it again last night. Based on magnitude estimates taken from a blue and red original image, it appears to be about magnitude 15.8 in Red and 17.3 in Blue.

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.

From our Galaxy Log blog with M-65 in 2008 and from this past week. I have not had a chance to visually go for it.

Thanks, and you can see the full size image at the GL blog. FrankC is our (CAS plus Galaxy Log) "lead" imager and also my B.P., for I'm not into astro-imaging... just an eyepiece guy

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...

Poor seeing is better than seeing snowflakes. I'm going to give it a try tonight.

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
or bias).

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.

I plan to try for this one tonight. I don't expect to succeed but I might. I have a 20" but my skies are only around 5.3 NELM.

Good luck with your 20" - your 5.3 NELM seem like 'heaven' with mine rarely better than 3.5 NELM - at least my sky isn't 'cluttered with stars'
Here's my 30s shot from last night

I tried with no luck Thursday night from a green site with only average conditions. All night the galaxy views never "popped" like they do on a good to great night out. Still better than not observing from the couch.

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.
