A Possible Naked-eye Comet in March, A Better One in December.

Quote:
Feb. 6, 2013: Far beyond the orbits of Neptune and Pluto, where the sun is a pinprick of light not much brighter than other stars, a vast swarm of icy bodies circles the solar system. Astronomers call it the "Oort Cloud," and it is the source of some of history's finest comets.

One of them could be heading our way now.
You can watch the stories video or the same here, the skyplot starts at 2:50 of the video:



Skyplot is for viewers residing in the Northern Hemisphere at 40° North Latitude.

This link shows more about the the emergence of PanSTARRS on Friday, March 8th: https://waitingforison.wordpress.com/comet-panstarrs/

Comet of the Century?


Quote:
Jan. 18, 2013: Out near the orbit of Jupiter, a faint speck of light is moving through the black of space. At first glance it doesn't look like much, no brighter than a thousand distant stars speckling the velvet sky behind it; indeed, it takes a big telescope make out that it is a comet.

But what a comet it could turn out to be….

Later this year, “Comet ISON” could blossom into a striking naked eye object visible even in broad daylight.




Orbital elements & Ephemeris: C/2012 S1 (ISON)
MPEC 2012-S63 : COMET C/2012 S1 (ISON)

There will be more information on Comet ISON as we draw closer to October, and November.

Your welcome!

Now don't forget, The lowest Minnesota State line Latitude I can find is about 3.3° higher than mine in Pennsylvania (40.28°N), so, the graphic from Sky&Telescope will be about 1/2 to 1 day later than what I would see.

You may already understand this, but let me try to explain; It all depends from which direction the event approaches Earth.

Since you reside on a higher degree of the Earth's latitude, it takes longer for observations to enter into your view, if the event is coming from the Southern Hemisphere.

If the event was originally coming from the Northern Hemisphere and heading South, we would see it before the Southern Members of our Forum.
In any event, I'll let you know the first instance I see it!

We should be able to see the tail a few days before we can see the nucleus, the actual body of the comet.

Your welcome John.

I don't if you've seen theses sites, but I hope they will help:
Will Comet ISON put on a show from the southern hemisphere near the end of 2013? | Sydney Observatory

This one's for PanSTARRS:
Astroblog: Viewing Comet C/2011 PanSTARRS in the Southern Hemisphere

It is coming close to the end for PanSTARRS in the Southerhn Hemisphere. When ISON gets closer you may find that Ian, from the astroblog, will be concentrating on it.

I like his disclaimer... Be careful out there, I'm not your mum.

It's getting to be that time when observers in the Northern Hemisphere will have a chance to see Comet PANSTARRS. It will be very helpful if you have an unobstructed view of the Western horizon.

To give you a better understanding of where to look the following simulations (sim(s)) are screenshots taken from my Stellarium, 0.12.0 planetarium program.

You can find information on the position of the comet in the upper left-hand corner of the sim.
For compass readings look to the ninth and tenth entries from the top after the title called Az/Alt | explanation These are coordinates to help you find your direction of view.
  • Azimuth matches readings on a compass.
  • Altitude is how high in degrees the object is above the horizon. 10° is approximately the width of a man's hand held out at arms length. (Tip:your thumb should be facing up.)
  • PANSTARRS will be the white dot in the center of the red reticle
  • In each sim you will see the date progress, but the time will remain at 20:00hours est, this correlates to 8pm est.
  • The second and third sims will be helpful as they give you a better reference point with the Moon as a guide.
  • By the 26th PANSTARRS will be almost out of view, and you will notice the evening sky becoming lighter. Daylight Savings Time will go into effect on March 10th 2013 for most of the US.
  • Additional Information: If you notice a difference in the Moon phase between the sims and the skyplot image I posted in my OP, that is because of the zoom factor used. To give you a better perspective I may have only succeeded in confusing you, the Azimuth remains almost due West at 269°. See fifth sim.
  • There are observers that make a hobby of trying to view the newest of new Moon's: Moon Watch :: An Einstein Year Project
  • These sims are plotted for 40.28°N Latitude if yours is higher you will see PANSTARRS lower, conversely if yours is lower you see PANSTARRS higher in the sky.

I will be posting more on Comet ISON as we get closer to the middle of Fall here in the Northern Hemisphere.

May you have clear skies, and good viewing

I found another visibility aide to help find PANSTARRS.
It steps through the next eleven days in the first 30sec., then three quicker runs to March 25th:

IC, I'm sorry to be the one to have to tell you this, but now that PANSTARRS is viewable in the Northern hemisphere it is no longer visible in the South. Your time was from the Holidays last year to the end of February.
