Hi sketchers

 

I receive this very morning 2020/11/26 a nova alert

Not too late to make a try

 

Here's the sketch of the field (F.O.S. 1°) made with a Mewlon 250mm & EP 40mm

 

NovaPer-2020-t-curve_l.jpg

 

My best visual magnitude estimation give +9.9, maybe this star will become more and more brillant ?

 

Position and first label : TCP J04291884+4354232 = TCP J04291888+4354233

 

Be safe and... out

Michel

Are the cardinal directions north-east- south-west)

imposed on your sketch correct ?

best regards

No you'r right, W is to the left, but North is ok.

Thank you !

I'll correct the sketch

That is our new summer home.  We started construction a couple of months ago.  I'm surprised it shows up in aerial photographs already.

Likewise, a good possibility might be that it is in reality a WZ Sge type dwarf nova in outburst, given its rather faint current magnitude. That has proven the case for quite a few recently reported newly detected objects initially reported as "novae"

Michel,

 

Nice, I'll need to take a look at this one.

 

Frank :)

Nice catch!

 

Was out last evening and estimated the magnitude at 9.5 - 10.0.

 

Edit: Having compared the brightness with close stars I firm up the estimate at 9.6.

The official classification of this star is a classical nova.

Thanks, I barely managed due to cloud. It’s really brightening isn’t it!

Hello Michel,

 

Thank you for the notification and the finder chart!  I've just observed it with my 12" Dobsonian at 49x magnification. It fits into the field of view with NGC 1582 and is nice to watch together with this cluster even at almost full moon.

 

And it seems to be even brighter now. I estimated it to be 8.3 mag (November 27, 17:10 UT). Can anyone confirm this?

 

Clear skies,

Robin

I haven't received any new estimation since this morning. So you're probably right, but ... wait and see.

I wonder when we can see a beautiful bright nova in our Galaxy, I remember that of Nova Cygnus, a long time ago that was in 1975, I have already regularly followed its magnitude, with a maximum of +1.9.

So when can we observe such beauty ???

Michel

hi all,

 

I saw now this nice nova too.

 

I measured:

7.8" Dobson, V 33x

~ 8.8 mag

Hi,

 

Normally I sketch for my own amusement or to keep track of asteroids.    I took a look for  Nova v1112 last night from my backyard in the city with a bright nearly full moon.    The nova was easy to find.   I used my 127 mm Mak on a non-goto tacking EQ mount.

 

It is worth a look.

Nice sketch Peter !

I like to put side by side all the novae I observed, mainly to see the curve differences.

 

Ofcourse the CN file size limitation give this view complicated.

 

TDC_17novae_l.jpg

 

We see that the curves are very different from each other.  This is what's interesting for novae, this is not the case for the SN when all curve are there quite similar.  The interest fort SN is the proximity of a nice galaxy, so I compile the same type of table, as I do for comets.

Those are nice souvenirs for my "future" old time.

Quite a collection, Michel!  bow.gif   

 

I planned to go out last night before moonrise to look at Nova Per but was delayed because I forgot that WV was playing #1 ranked Gonzaga (basketball) so by the time I went out the Moon was high and bright and some haze had come in.  With my 12x36 IS binoculars, I could see the triangle of stars (57, 58, and 59 Persei) that are near  NGC 1582 but I could not see anything dimmer than that.  Thought I'd try again tonight but clouds came in earlier than forecast.

Hi Michael, 

I hope that the winer was,... heu. confused1.gif

Yesterday I made my best estimation, between 8.2 and 8.3, maybe the maximum-maximorum for this nova ?
