AAVSO Special Notice #337
Bright transient near the galaxy NGC 5643 (Lupus) February 15, 2013
As noted by Alexandre Amorim in the AAVSO Forums, a bright transient has appeared in the fringes of the face on spiral galaxy NGC 5643, and has been published on the Transient Objects Confirmation Page at Harvard.
(See http://www.cbat.eps.harvard.edu/unconf/ ... 13278.html
for more information.) Rod Stubbings has since provided confirmation of the transient, estimating it at m(vis)=11.9 on 2013 Feb 15.514 (JD 2456339.014); we are not yet aware of spectroscopy that enables classification as a supernova or any other source. This object has been added to VSX with the temporary designation PSN J14323388-4413278 .
Observations of this object are encouraged to determine its nature and follow the outburst.
Both visual and CCD observations are encouraged, as is spectroscopy; spectroscopy could enable classification of this object, and should also be reported to CBAT (see http://www.cbat.eps.harvard.edu/unconf/tocp.html for details).
The object is located at the following (J2000) coordinates:
RA: 14 32 33.88 , Dec: -44 13 27.8
A sequence for the field has been created by Mati Morel, and is available through AAVSO's Variable Star Plotter ( http://www.aavso.org/vsp ).
If this object is confirmed as a supernova, we will issue an Alert Notice within 1-2 days.
Please promptly submit all observations to the AAVSO via WebObs using the name "PSN J14323388-4413278".
