A new “star” popped up late last week.  I didn’t get an opportunity to take a look until night before last. I was glad I did too!

First things first, this Nova was discovered by Koichi Itagaki (Teppo-cho, Yamagata, Japan), reported by S. Nakano (Sumoto, Japan) on August 14, 2013. Initially it was pretty bright at a mag. 6.8. By the time I got skies it was in the mag 4.5 range.

The moon isn’t helping because it is washing Nova Delphini out a little but this is still a BINOCULAR target! I’ve seen it in both the scope and binoculars.

If you have fair skies you can take a look (provided you can see the stars Deneb and Vega in the northern hemisphere). I’ve included telescope coordinates for those with telescopes.

If you don’t have a scope or don’t have the faintest idea how to use the one you might have access to other than set it up and point it. Here’s how to find it:

Two methods:

The first is how I found it with binoculars you can refer to a finders chart, and by the way the location marked is only approximate however the coordinates are correct.

Find Vega / Find Deneb both are easy and bright, now find Altair. Draw a line from Altair (the moon works too) to Deneb look along that line until you are across from Vega. It is the bright spot apart from those larger stars.

Another way is to to use a compass and orient yourself at:

Azimuth = 105°17′  and
Altitude 59°25′ .

That will put you right near it.

I did not get a camera on it due to less than desirable atmospheric sky conditions and a barn fire about a mile away (no animals were hurt) puring out smoke, but my brother Andrew, despite his own very milky skies did and the image above is his. Thanks bro!

Here is a very nice image from Efrain Morales via Flickr taken on August 16, 2013.

Like I said the moon is bothering things some, but if you get a chance try taking a look.

  1. Thanks, I do like the graphic on your link so I changed it out. I knew that mine was horse shoes and hand grenades kind of close if you know what I mean. That’s why I had put the coordinates in there. 🙂

    [Edit: LOL. My blue dot locater was supposed to be at the Bottom of my Label, I must have moved it when I moved the label as it was in the same PS layer. Sadly I “flattened” the image and cannot easily fix it. Thanks again!]

  2. The stars in the constellation itself range from around 97 to 400 light-years. Some of the fainter stars are in the 900 to 1,000 light-year range. I’ve not seen a good distance for the nova yet. It’s a great question and one Ive been trying to find out too. We need to know is what the progenitor star is. Distances are very difficult to get.

  3. Tom I just discovered your site, and bookmarked it, since it’s providing a lot of information for an amateur astronomer like me. My questions are– is there daily (or nightly!) info regarding the nova’s brightness? It is still getting brighter, staying the same, getting dimmer? And I’ll keep checking to see about it’s distance. Thanks!

  4. I can’t find what I think you want, not conveniently formatted at least. Just did a quick look though, seems like there should be. I do a bit more in depth searching.

    Kind of an interesting place is at the AAVSO, this page will let you put in parameters and it will generate a light curve.

    Use the object name: Nova Del 2013, also you can leave the start date open, seems to work fine.

  5. Tom, the AAVSO site’s light curve display is just what I was looking for, thank you!
    And now I have yet another website to explore.:)
