[vsnet-alert 13654] Re: Possible Transient in Scorpius

[hambsch at telenet.be]

Dear all,

I have also taken time series images in V and I of this object last night from Chile using a 40 cm f/6.8 telescope and CCD. I identified a bright object at the coordinates given in the AAVSO Special Notice #251.
Data analysis is still pending and I hope to have results tonight after being home.

Best regards,

F.-J. (Josch) Hambsch (HMB)

Hi All

Following the posting on the Central Bureau's Transient Object
Confirmation Page about a possible transient in Sco  (TOCP
Designation: PNV J16364300-4132460) and AAVSO Special Notice #251, we
performed some follow-up of this object  remotely through the 2.0-m
f/10.0 Ritchey-Chretien + CCD of "Faulkes Telescope South" (MPC Code -
E10).

On our images taken on September 07.50, 2011 we can confirm  the
presence of an optical counterpart with filtered  R-Bessel CCD
magnitude 9.1 (USNO-B1.0 Catalogue reference stars) at coordinates:

R.A. = 16 36 44.29, Decl.= -41 32 37.7

(equinox 2000.0; USNO-B1.0 catalogue reference stars).

According to VIZIER there is a 15.08 R1 magnitude star at 0.060
arcseconds from the transient position (USNO-B1.0 0484-0459316).

our confirmation image and the archive POSS2/UKSTU plate (R Filter -
1997):
