nice one. I am imaging closeup now

Good one Paula. Just a bit fainter than Epsilon Crucis. Seems we southern hemispherians were destined to be compensated for no Comet ISON with a nova.

Thanks Dave, look forward to the close up.

Thanks Tom, we did get treated to something special.

Great capture Paula.

Nice shots Paula,

The distance away of this Nova seems controversial:

As of yet, there is no firm distance measurement for Nova Cen 2013,
though radio observations with southern sky assets may pin it down.
One northern hemisphere based program, known as the EVLA Nova Project, seeks to do just that.

But it says here:

So, with enthusiastic hand-waving, we can say the nova lies between 5,700 and 10,000 light years from Earth.

Well done, Paula

An ATEL was posted yesterday at http://www.astronomerstelegram.org/?read=5639 Pontificia Universidad Catolica de Chile Observatory. They have among other things made a measurement of the interstellar extinction, i.e. how much the light has been affected by interstellar dust, which gives a crude distance measurement.

we have preliminarily estimated ... a low extinction and a not large distance for the nova

Thanks.
It's amazing that they can be so sure about these distances.
How do they know that it's not coming from a supernova in a distant galaxy?
They obviously think that it's not far away in our own galaxy.
