Viewing Outlook

In fact, the weather was supposed to be cold and cranky last night (10/9). Instead, it was warm and crystal clear... perfect weather to do a mini star party with the Park City Cub Scouts.... and that's exactly what we did... out pretty much at our regular venue... Trailside Park.

Private Star Party

Astro Humor

Feeling the need for relaxation after the events of "The Red-Headed League", Sherlock Holmes and Dr Watson went on a camping trip. After a good meal and a bottle of wine, they were exhausted and went to sleep. Some hours later, Holmes awoke and nudged his faithful friend.
"Watson," he said, "look up at the sky and tell me what you see."

Sleepily, Watson replied, "I see millions and millions of stars."

"And what does that tell you?"

Watson pondered this a moment. "Astronomically," he said, "it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Timewise, I deduce that the time is approximately a quarter past three."

Taking Holmes's silence as approval, Watson continued with growing confidence, "Theologically I can see that the Lord is all-powerful and that we are small and insignificant. Meteorologically, I suspect that we will have a beautiful day tomorrow."

He paused, and looked over at the Great Detective. "So, Holmes, what does it tell you?"

Holmes shook his head in disgust. "Watson, you idiot, someone has stolen our tent."

Planetary Report

Mercury, the 1st Planet

Venus, the 2nd Planet

Venus is now rising little more than an hour after the sun. You should now be able to find it in the evening sky shortly after sundown. In fact, now would be a good time to start watching Venus. Why? Well, because Venus is getting ready for some major changes. It is currently 97% illuminated. As it climbs higher in the sky over the coming months, it will grow considerably in size and brightness... while shrinking just as considerably in phase. 

The accompanying image show the scope of the changes which we'll be seeing.

Earth, the 3rd Planet

It may not be summer anymore, but you wouldn't have known it on Sunday. Skies were clear and temps were unseasonably warm. We just couldn't let a day like this sneak by without doing something outdoors. So... we headed down to The Harvest Festival at The Sundance Ski Resort. I took the following shot while riding up the chairlift. Is this a gorgeous state, or what?

I took the accompanying image in March of 2002 using an Olympus OM-1 with Fuji ASA400 shooting at prime focus through a 120mm f/5 refractor 

Mars, the 4th Planet

Utah Skies own Don Brown took this beautiful shot from his home in Park City, Utah on Wednesday evening (10/08/03). I've got to tell you... views have been really nice lately. I hope you've gotten a chance to get out and see Mars. It's really quite impressive... even without a telescope. I try to make it a habit of at least poking my head out the window before going to bed.
Mars continues to shrink... at a barely noticeable rate, but...... it now spans 19”...  roughly 25% off it's peak. If you haven't seen it yet through a telescope, don't fret.. but don't waste a whole lot more time. Break out your telescope and checkout the red planet. Mars is still incredible to look at... and will continue to provide great views well into the fall. 

If you'd like to get a feel for the rise and fall of Mars, checkout our own Mars Observations Page. Utah Skies own Don Brown has been capturing images of the Red Planet since May. The change is simply incredible. 

If you’d like to checkout Mars for yourself, all you need to do is look high and towards the southeast around 9pm or so.. Mars is so bright that you just can’t miss it. Mars is still fairly close to it's peak... when it was bigger and brighter than at any time in over 60,000 years! Why is this you may be wondering... Earth and Mars both orbit the Sun on different paths and at different distances. This summer, both planets will be on the same side of the Sun. This type of alignment, known as Opposition, occurs about every 26 months. No big deal, right? Well... that depends because the separation at opposition varies considerably. On August 27th, that distance will be about 35 million miles. At the previous opposition in June of 2001, the distance was 41 million miles and in 1995 it was almost 70 million miles. So... what can you expect? Well.. only the best views of the Red Planet in your lifetime! Mars will shine at mag -2.9. This is about as bright as Jupiter ever gets... and far brighter than it's been in quite some time Additionally, Mars will have an apparent diameter of 25". That's about 50 percent larger than its current size. Still not convinced? Want even better views? Well, short of climbing aboard a spaceship (not completely out of the question nowadays) you'd have to wait until 2287 for a closer peak.

Jupiter, the 5th Planet

 

Rising:		4:30 am
Visual Magnitude:		-1.77
Visual Diameter:		32"
Distance:		6.14 AU
Constellation:		Leo

 

Saturn, the 6th Planet

Saturn's rings are now tilted wide open to us... roughly 27° from edge-on. Over the next 15 years, they will move from wide open.. to edge-on to wide open revealing the other pole. This and next year will be the best time to study Saturn's beautiful ring structure for some time, so... get out there and do it.

Saturn is now rising before midnight and should make a good target for several hours before the Sun puts it to sleep. Saturn will continue to improve through the fall and into the winter.

I took the accompanying shot Tuesday morning from my home in Park City.

Uranus, the 7th Planet

Neptune, the 8th Planet

Springtime on Neptune? Yup... that's what the latest observations seem to indicate. The southern portion of the 8th planet is having some spring like conditions.  Spring is always a fun time of year.. and that's a good thing, because spring last for over 40 Earth years on Neptune. 40 years? Yup... Because it takes Neptune 165 years to orbit the Sun, seasons last just a smidge over 40 earth years.

The accompanying image shows the various cloud formations which inhabit Neptune's upper atmosphere.

Pluto, the 9th Planet

Astronomers made a surprising discovery about Pluto recently. As Pluto begins to move away from the Sun... towards the beginning of it's winter... things are actually heating up on the distant planet instead of cooling down. Checkout CNN.com/SPACE for more details

Take this bit of planetary information either as an interesting side note, or an observing challenge. Pluto is in the constellation Ophiuchus, less than °1 southwest of NGC6309 aka The Bug Nebula. I viewed The Bug this past weekend, so... photons from Pluto must have hit my retina :-) At magnitude 13.9, Pluto is basically out of reach of smaller telescopes... Even in the big scope... it's difficult to be sure that you've seen Pluto. One way to verify that you have found Pluto is to sketch the star patterns over several nights. If you have actually found Pluto, one of the the faint star-like objects will have moved over the course of a few nights. This is Pluto.

This  image was created from The Nordic Optical Telescope.
