This recurrent nova in its calm phase has an apparent magnitude of 12.5. We have already observed eruptions in 1898, 1933, 1958, 1967, 1985, 2006 and today from August 8, 2021

I had the opportunity to travel to the high French Alps mainly for Perseid observations (sketch to come), just on time during the explosion phase of RS Oph,

Look at the rapid decrease in magnitude and notice the change in color.

Today the show is not finish !

 

Clear sky to you all

Michel,

 

This is a very nice record of the most recent outburst of this recurrent nova. It explosively bursts and settles back down pretty fast. Nice record of the color change with the magnitude drop.

Fine sketching record here.

 

Frank :)

Michel,

 

Great set of sketches!  Love the widefield view.  waytogo.gif   

 

I observed RS Oph at 0240 UT 13 August with my 12x36 IS binoculars.  I estimated its mag at 6.3.  I didn't see any color.

 

This was my first recurrent nova.  I did not sketch because weather prevented me from making a series of sketches--I was lucky to see it when I did.

Nice observation/sketches! I'm hoping my skies can clear up so I can see this one, I was lucky to see the one in Cassiopeia recently!
