MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 05h 43m 17.95s +09d 31m 14.8s on 2012-09-30.78510 UT. The OT unfiltered magnitude is 13.4m (limit 17.9m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2011-11-02.73236 UT with magnitude limit in 'V' filter 18.8m.
There is a faint star (magnitude ~21) within 1.5" from the position of the OT visible on POSS-II plates. Color-combined (BRIR) DSS finder chart is uploaded to master.sai.msu.ru... (10'x10' FOV).
There is nothing at this position in USNO-B1.0, GSC 2.3.2, 2MASS, 1RXS and GCVS catalogs and in AAVSO VSX. This area is not covered by SDSS, CSS and GALEX. Nothing is visible on the sum of 3 NEAT images of this filed taken on 2001 Sep. 23 (limiting magnitude 20.5).
The galactic latitude is 10.5 deg. Based on the amplitude of variability (more than 7 magnitudes) we suggest that MASTER OT J054317.95+093114.8 is likely a cataclysmic variable (dwarf nova or classical Nova) in outburst.

It means nothing to us. However, its cool.
A nearby supernova (which is completely a different process than a nova), could cause a second "sun" in the night sky, making night as bright as day for a few months. And we will hopefully get to see that in our lifetime...there is a nearby star that will probably go supernova "soon"..... But even then, no cataclysmic events.edit on 2-10-2012 by phroziac because: (no reason given)

A nova is the result of an exploding star and is an extremely energetic event. By the magnitude we can tell how bright the object is the lower the number the brighter the object. An 8 is pretty bright en.wikipedia.org... for comparison sake Sirius is the brightest star in the sky and it's a -1 of magnitude. This event should have no impact on us physically it's just real cool for amateur astronomers.
