[vsnet-alert 21162] Re: Please check V906 Oph

>>> Please check V906 Oph
ASAS-SN detection.  This is a classical nova (1952).
The object has been positively detected on four most recent nights in the 
ASAS-SN data.

V0906Oph 17:26:09.70 -21:54:28.00 <<<


The chart in IBVS 2585 has a very low resolution but the star marked is 
approximately 70" away (around 17 26 15 -21 54.6 J2000.0) from the current 
GCVS/VSX/ASAS-SN position. There are two Gaia objects of G mag. 20.3 and 
18.4 in this area, 9" to the NW of a 15.7 mag. star (2MASS 
J17261534-2154425).

Duerbeck's reference catalogue and atlas of galactic novae identifies it as 
2MASS J17261602-2154389 (V ~17.6 according to GSC2.3) at 17 26 16.02 -21 54 
38.9 (J2000.0) mentioning the low resolution charts available and the 
uncertain identification.
Downes comments that Duerbeck's identification should be discarded.

There are no observations of the nova in quiescence so any observations in 
this field would be useful.
It would be interesting to confirm the ASAS-SN brightening at the currently 
catalogued position of V0906 Oph.

Cheers,
Sebastian
