As you maybe know, I like to have a look at some exotic objects in our universe .

Try this one, as a very special system.  On top of that this is a very easy observation to do, mainly in the morning.

The system's J2000 coordinates are 18 20 21.95, +07 11 07.3.

The magnitude I estimated this morning was +/- +12.3 and probably brighten.

Clear sky to you all

Michel,

 

This is a very impressive observation and sketch.

Way to go.

Thanks again Michel, if you didnt post it I wouldnt have known about its existence

Thank you all for your friendly comments.

Yess Migue you get it, it's nice to see that.  Your sketches are great and very accurate.

Clear sky to you all

If I had a very short focus EP and a very long refractor plus a special laser to cancel the atmosphere bugs ,

that's what I can maybe see:

 

 

I did this watercolor just based on what I suspect this exotic object could be.

This morning 22/3/2018 3:48 UTC my visual estimated magn was +12.3, quite stable.

This morning (03/23 4:00 UTC) the magnitude was +/- +12.2

 

 

Clear sky to you all

Thanks for the heads up on this Michel.........

 

I was up earlier than planned this morning after thinking we heard a prowler out front.

 

No one about but lovely clear and steady-looking sky......I was planning for Jupiter, Mars, and hopefully Saturn; but up so soon I took a first look at the outburster, and delayed with Jupiter.

 

Made it 11.8 (AAVSO chart): and at that level I start to get colour impressions (fainter – with reddish objects).  Tho’ here not so sure if I quite got a reliable impression – more of a ‘sensing’ – of an intense bluish; which seemed to vie with contrasting it with the orange 10.9 star to its north.

 

Good views of the three planets (first this/their apparition....!).  Hope to post later – when I make up some lost sleep............!

You welcome Dave

The magnitude you mension is exactly the one I estimated this morning:  +11.8.  With my small aperture refractor I don't see any clear color for this object however I have also something like a 'sensing' impression but this one for a rapid magnitude change in comparison with the near +12.0 star.  Maybe we dream there...

[David Gray]

Thanks Michel glad we get similar magnitude for it, albeit not on the same date..

 

I hope for another look at the colour:. Looking on some sites today I failed to spot

any B-V values......but some comments about it *red-flaring*.......??!

 

A closer/longer look next time methinks.....

Yes just one day difference but the curve is rising very slowly, so our two estimations are matching.

For the color I don't know, AAVSO is asking for white light estimation only, that make more difficult for B-V info... I don't see yet any observation out of V.

Michel,

 

Getting a little brighter. I would really like to see this live through a telescope.

That must be easy for your lattitude, high in the morning sky.

Except for the maybe red-flaring color from Dave or my maybe magnitude quick variations, it looks like a common star.

Ok but when you know what it is,...
