I observed S CrB last night and found it notably fainter than eta CrB. My estimate is mag 5.6

Clear skies,
Finbarr.

Great job, Finbarr!
+5.6 sounds very good. 

We are being promised clear skies on Wednesday night. 
(I'm at a church party on Tuesday night). 
It's a guarantee that I will observe S Crb. 

Clear skies for this one, Aubrey.

Fermidox post=111326 userid=1800I observed S CrB last night and found it notably fainter than eta CrB. My estimate is mag 5.6

Clear skies,
Finbarr.

Hello again Finbarr.
I see eta Crb has a magnitude 5.6. 
It's an extremely tight binary - too tight for my apo refractor. 

Best regards from Aubrey.

I'm not sure my post got through. 
Here it is again. 

Hello again, Finbarr. 
I see eta Crb has a magnitude of 5.6. 
It's an extremely tight binary - too tight for my apo refractor.

That's funny Aubrey, I did see mag 5.55 on Stellarium for eta CrB, but AAVSO says 4.99 and Wikipedia 5.02?

Yes, Finbarr. 
It all seems very confusing. 
Burnham states that eta Crb A is 5 and a half. B is 6.
Sissy Haas gives A as 5.6. B is 6.0. 
Guide 9.1 DVD varies from 5.0 to 5.6. B is 6. 
Simbad gives A as 5.6. 
Wikipedia gives A as 5.0. 

Who are we to believe?
If the experts cannot agree, then how can we suss it out?
Madness!
And we trying to estimate S Crb. 

Best regards from Aubrey.
