Hi, this supernova was discovered at Lick Observatory on May 28th, it's a type Ia supernova with magnitude 14.2 now, easy to detect under a good sky with a 12'' and less. It shines with the bright of 1.000.000 of suns, absolute magnitude -17.5. If it was at Sirius distance, it would shine with magnitude -24.5 (our sun has a magnitude -26, so we can imagine...). Have you seen it?

Migue,

 

An excellent observation and information of the new supernova in NGC 4125. Thank you for sharing it with us all.

 

Regards,

Carlos

Migue,

 

That is a great rendering of the galaxy and supernova.   :)   I have not seen this one and might not be able to before it fades--very poor transparency in the forecast day after day until Monday.   :(

Wow Migue!  I certainly will not be able to see this. Your sketch is superb.  Just think about the time scale and distance you've seen and captured with your graphite!

Regards,

Randolph

Great capture! It's been 5 days of solid cloud here in south east UK  :shocked: Not a glimpse of the black (or blue) stuff

That's a great news Migue, thank you a lot to post this here, that will be my next target with my equivalent Dob 12", for sure!

Gracias

Nice catch! This one's probably a little too faint for me to spot in my 10". I've been looking to observe another supernova, I haven't caught one in a few years. I'm hoping that ASSASN-16fq becomes <13.5.

Saturday night it was easily seen in my 12.5 -inch Dob with direct vision. Averted vision was needed in a nearby 6-inch SCT.  The night was hazy with poor transparency and seeing.  My magnitude guess would be 13.  

 

Not sure when it will peak since it was discovered while still rising....  Worth a try in almost any scope!!

Just after the rain, we had a nice observation with the OAB telescope yesterday night.

This SN is indeed quite easy to find, and ofcourse very easy with this 25" mirror.

 

Here the observation sketch:

 

sn2016coj_l.jpg

 

Comparing with the stars in the field of sketch, the estimated magnitude of the supernova was more or less around 13.0.

We try the SN in M66 as well but unsuccessfully

Thanks to Migue, that was a nice target.

Thank you all for your comments and great sketch Michael, thanks for sharing that beautiful sketch! Magnitude 13? Wow. I will see it again this night, it seems it's getting brighter!

I observed SN 2016coj last night using the Naylor Observatory's 17" f/15 classical Cassegrain at 324 and 463x. The supernova really stood out at the latter magnification.

 

I was unable to see the supernova in M66 but was not surprised by that fact.

I got a pretty good look at the supernova this morning and made this sketch.  Report is here.  

 

Nice sketch, Michel--looks like we're really on this one.   :cool:

Great sketch Michael! I could observe it again 2 nights ago and it was a bit brighter than the previous day, just more like your sketch! I would like to observe the new supernova in canes venatici, but the clouds and things to do won't let me.

Thanks, Migue.   :)   The SN seems to be holding its brightness but it must be close to falling off--it's been about 14 days now.

 

I know about those clouds and things...

Here a watercolor I did from a "bad photo" I take at the end of this SuperNova session. You will see at the EP Olivier who is the owner and the creator of this observatory.  Thank you Olivier!

Michel- Love the watercolor of Olivier at the eyepiece of his observatory.

Michel that is wonderful!  There is an air of dignity in that painting...I could imagine this as  perhaps ( given the hair and I mean this in a complimentary way! ) Albert Einstein at the eyepiece.  The chart in his hand, the red illumination, the stars in the sky...what an atmospheric effect.

Regards,

Randolph

Hello Megue, 

Very nice presentation. The sketch is very nice. 

 

My sketch of supernova. 

 

10inches at 255X from my backyard. 

 

Kind Regards 

Marios
