Your report is wonderfull !!! What a level Florent!! Using speckle!!! It is a pleasure that you be present in our group. Have you used the 0.4 meter telescope?? Is excellent that you be able to resolve well below one arcsecond!!
do you know what is the magnitude of Aa component?
I think that I have same intereting work imaging same components of new Benavides' binaries which we suspect be an unresolved binaries.congratulation Florent! you are great!

Hola Florent!!:
Tu informe es maravilloso!! Estupendo nivel usando la técnica speckle!! Es un placer tenerte en nuestro grupo. Has usado el telescopio de 0.4 metros? Es fantástico que seas capaz de resolver pares bien por debajo del segundo de arco!!.
Creo que tengo un trabajo interesante para tí, observando algunas de las componentes de las binarias de Rafael Benavides, las cuales sospechamos que podrían ser binarias no resueltas.
Felicidades Florent! Este genial!

Congratulations Rafa for this new system. With no doubt the SE elongation you saw is real and can be seen on the following image. As you stated the secondary is currently a bit more distant than 2".

But the story doesn't stop there...
While reducing on the fly when imaging, I was surprised by the strange shape of the main component.
So I decided to took two new series with shorter integration time, I got this autocorrelogram :
and the composit of four good images in spatial domain :
Another component is obvious !
Now the measurements, three series of image last night at 02h24,02h38 and 02h59 UTC. Under an heavy "Moon polluted" sky with intense diffusion caused by thin high altitude clouds, nevertheless a good seeing.
Naturally, these measurements must be taken with some caution regarding the faint signal under this sky. Particularly those of Aa which are just four times the sampling.
I call AB the large couple and Aa the surprise :
AB pair :
theta : 127°5 rho : 2"45
theta : 127°2 rho : 2"42
theta : 127°8 rho : 2"43
deltaM : 1.2
Aa pair :
theta : 254°8 rho : 0"65
theta : 254°4 rho : 0"65
theta : 255°4 rho : 0"66
deltaM : 1.1
Un abrazo desde Francia,
Florent
Sorry for the english. In the future, I'd better spend my holiday in Spain
