Latest Nova Del 2013 observation

There are currently almost 24 million variable star observations in the AAVSO International Database, as per http://www.aavso.org:

The 23,935,137th observation was of Nova Del 2013, my 111th variable star observation. All 111 have been visual estimates; a modest number.

Here’s the light curve now:

Adding a binned means series (0.25 days per bin) and a polynomial fit (both against the Visual series) gives an impression of the overall changes since the initial outburst.

From looking at this, the nova seems to be on a gradual decline, but in fact it could still rise in magnitude again as Mike Simonsen points out in this AAVSO post with reference to another nova in Delphinus in the 1960s.

So, keep observing!
