R.A. 05h10m32.58s  Decl. -69°21'30.4"  (J2000.0)

A possible progenitor (21 mag) is listed in "The Initial Gaia Source List (IGSL)" (Smart, 2013) and the "Magellanic Clouds Photometric Survey: the LMC" (Zaritsky+, 2004):
- IGSL3 (05 10 32.580 -69 21 30.60): BJ= 21.288, RF= 20.810, G= 20.931 mag
- MCPS (05 10 32.56 -69 21 30.9): B= 21.490, V= 20.828, I= 20.547 mag

This possible nova is located 2' from SAO 249214 (V= 8.7 mag) and 9' from Nova LMC 2005.

Spectroscopy is urgently required.
 
Clear skies,

Good Day All,

This optical transient (N?) was observed on May 13.4 UT at Vmag 13.24 (0.04), comps BLX 874 and 876.

The relative colors around that time were:

U-B =  -0.59  (ie: UV-bright)

B-V = +0.05

V-Rc = +1.25

The star apparently isn't in VSX yet. As soon as we have an AUID, I'll put the data in.

kind regards,

Steve.

Spectroscopically confirmed as a nova by Terry Bohlsen.

I have added it to VSX.

I have had some e-mail problems, sorry for the delay.

Cheers,
Sebastian

After some pointing problems I managed to get a RVB series. In addition I found a series of the Large Magellanic Cloud from 2015 where it is not visible. I'll figure out how to measure them properly any time now.
