Just two days after Nova Centauri 2013 became the brightest nova seen in our skies since 1999,  it has crashed in brightness to around magnitude 5.

Whetehre we will see another outburst is uncertain, however, with the nearly full Moon in the sky the  nova is now very difficult to see without binouclars.

A close up comparison of the nova (indicated by the line, on the 15th and 17th, the dimming is readly visible.

Thanks Ian, at 0430 this morning, I was looking for it to be about as bright as Epsilon Crucis (my reference for magnitude 3.5ish) I could just see epsilon C. but not the nova. Now I know why.
