I wonder if other Keiper (so?) Belt objects are just as interesting. My hunch is that some must be. Sent from my iPhone

Now that Pluto has been found to have Geology, a complex surface structure, and its own Moons, I hope that Pluto will be upgraded back to Planet status.

Just thought I'd share in case those hunting for a SN are interested in setting their scope to scan this area. In M31 which has not had a visible SN since 1885 in SN 1885A there is a reoccurring Nova that is a confirmed Red Supergiant feeding material unto a White Dwarf that is aproachging the 1.44 mass limit before going into a Type Ia. The reoccurring Nova, M31N 2008-12a is located at RA = 00:43:26.66 Dec = +41:23:30.8 in M31, the Andromeda Galaxy. M31N 2008-12a has erupted in 2008, 2009, 2011, 2012, 2013, 2014. Here are some articles if anyone is interested:

The Nova seems to peak around limiting magnitude 18.2 or 18.3 and goes up to LM 20 to 22. A very faint object. However, when it goes as a Type Ia it should be MUCH brighter than that. So if your scope wants to and can scan that low you can take a look a perhaps capture the next SN to be seen in M31 . . . or not as it could be close in astronomical terms but not so close in terms of a human lifespan. Still, a good place to go and watch to increase your odds. I will post more on a blog post later today or tomorrow about it, and where roughly, visually this object is located in case a visual observer wants to just get to know the star field around that area and watch for a bright object to boost up. Robert Evans in Australia btw has 42 confirmed visual supernova finds so a visual person can learn to hunt SN's and find them, just a lot harder .

Oh btw, I will post later on what I am doing and I know that SLAS has outreach at SPOC but we are at the New Moon Window this weekend so either tonight or tomorrow night I am heading out. We'll see as tonight is clear but the winds are blowing 10 to 20mph and I don't like the wind. It may be tomorrow night (people clear out then also). If your interested I will post where but most likely this weekend is Vernon. I may try for Wolf Creek later in the week, but will post if I do that.
-- Thanks!

Weren't we always told Pluto is shaped like a potato? A
