The time taken for a nova to decay by 2 or 3 magnitudes from maximum optical brightness is used to classify a nova via its speed class. A fast nova will typically take less than 25 days to decay by 2 magnitudes and a slow nova will take over 80 days.[3]

Update on the Bright Nova Delphini 2013;
by Nancy Atkinson on August 16, 2013

<<Since showing itself on August 14, 2013, a bright nova in the constellation Delphinus — now officially named Nova Delphini 2013 — has brightened even more. As of this writing, the nova is at magnitude 4.4 to 4.5, meaning that for the first time in years, there is a nova visible to the naked eye — if you have a dark enough sky. Even better, use binoculars or a telescope to see this “new star” in the sky.

The new nova is located in Delphinus alongside the familiar Summer Triangle outlined by Deneb, Vega and Altair. If you aren’t able to see the nova for yourself, there are a few online observing options:

The Virtual Star Party team, led by UT’s publisher Fraser Cain, will try to get a view during the next VSP, at Sunday night on Google+ — usually at this time of year, about 10 pm EDT/0200 UTC on Monday mornings.

The Virtual Telescope Project, based in Italy, will have an online observing session on August 19, 2013 at 20:00 UTC, and you can join astronomer Gianluca Masi at this link.

The Slooh online telescope had an observing session yesterday (which you can see here), and we’ll post an update if they plan any additional viewing sessions.

There’s no way to predict if the nova will remain bright for a few days more, and unfortunately the Moon is getting brighter and bigger in the sky (it will be full on August 20), so take the opportunity this weekend if you can to try and see the new nova.>>

What other kind of nova could their be? If it weren't new, it would be a malnova.

It could be a recurrent nova.

Whoever named novas didn't put that much forethought into it.
You could propose novas be renamed to something long, mundane, and more correct.

<<In Chinese astronomy, the term "guest star" (ke xing 客星) refers to a star which has suddenly appeared visible in a place where no star had previously been observed and becomes invisible again after some time. The term is a literal translation from ancient Chinese astronomical records. Modern astronomy recognizes that guest stars are manifestations of cataclysmic variable stars: novae and supernovae. Still, the term "guest star" is still used in the context of ancient records, since the exact classification of an astronomical event in question is based on interpretations of old records, rather than on direct observations. In ancient Chinese astronomy, guest stars were one of the three types of "new stars", the other two being comets in modern understanding.>>

If it's been a long time since its last outburst, would it be an old nova? :doh:

Exactly. A malnova.
