This possible nova, is probably the known variable star V392 Per.

The previous visual range for V392 PER was 14.1 - 16.9, but tonight my visual estimation was 6.2 !!!

What an outburst!

 

 

As stated in the Observational Astrophysics forum by BrooksObs "If indeed this is a nova identical with V392 Per, this would probably be an event unique in the annals of variable star astronomy, as I cannot recall its like."

Clear sky to you all

Any further information about it?

Any further information about it?

All what I know comes from this link :

Here's a AAVSO curve where I define the 10 last years of observations

 

Today the magnitude was droping around +7.2 .

I read that the spectrum is very special too.

Looks like it is fading fast.

[Aquarellia]

Thank you "Early" you'r right.

Today the AAVSO curve gives +8, a straight forward function. I hope to have another hole between the european clouds this evening.

Thank you Tom.

Some news about this strange star:

April 5th 19:52 UTC, my estimation was 8.9, the decline looks more slow.

But from my observatory the estimation is now difficult, this star is too close to a tree, so I think I will cut partially this poor tree tomorrow...

Don't cut the tree Michel, it is needed for pleasure of your owns and the alert was settled.

Now this is an event I have to perform.

Transparent sky we have here now but with seeing not confidential, will try.

Good skies to you.

Thanks for the updates, Michel.  This article was in the weekly newsletter from Sky & Telescope ​for those of us who don't know much about variable stars.

 

Sadly, Perseus is too low behind the 1326 meter mountain to my northwest for me to try for it.

Too late, but it's just a partial cut, because you'r right, the rest of this tree and some other ones are masking street lights as well...

You welcome Michael.

Indeed this is another very good article from Bob King.

At final 2 trees to be shortenned at home.

On Friday night the 4th May, I found the nova to have quite a decent orange colour. 

I have no idea whether I will be able to observe it again, as there is a wide tree getting in the way. 

The Perseus  constellation is now moving into the northern sky.  

 

Clear skies to you all from Aubrey.

It looks that all over the world there is a global tree issue with this nova !

Michel

[flt158]

Perhaps somebody could produce a sketch when V392 Persei will have the current orange hue. 

That would be rather nice!

Here's your command Aubrey .

 

This watercolor shows my last observation, with +8.8 as a visual magnitude estimation.

With more than 100X a light reddish hue is clearly visible.

Not to mention the nights keep getting shorter. How much astronomical night do you get in Dublin this time of year? At 39 north, we are down to about 6.5 hours.
