Moon and Jupiter, August 2, 2013

Above: Waning Crescent Moon at 5:53 AM CDT August 2, 2013 (10:53 UT), 8″ reflector telescope with 25mm eyepiece.

Below: Jupiter and its four largest Moons offer an ever-changing space-scape, though in the photo below you can’t see Io, which was transiting Jupiter’s face at the time.

From left to right: Ganymede, Europa, Jupiter, Callisto, 5:29 AM CDT (10:29 UT).

Below: 29 minutes later, the lightening sky helps me photograph Jupiter’s atmospheric cloud belts. 5:58 AM (10:59 UT):

When the sky is darker, the photometer on my cell phone camera tries to take in as much light as possible, resulting in loss of planetary detail due to overexposure. But the lightening sky floods the camera with light, causing the photometer to kick down the light level, revealing more detail. Just something I’ve learned as a low-budget astrophotographer. :O)

Venus, Mars, and Jupiter, July 28-29, 2013

Venus and Jupiter are the two brightest planets, and these days Jupiter is appearing as a brilliant “morning star” in the east before dawn, whereas Venus is appearing as a bright “evening star” in the west after sunset.

Below: Jupiter and dimmer Mars close together in the predawn sky.
Mars is left center, brighter Jupiter is upper right. 5:23 AM CDT July 29, 2013, 7×35 binoculars.

Beautiful skies like this one keep me getting up before dawn:

BIG Sunspot, Waning Crescent Moon, and Bonus Critters, early July 2013

Above: My extremely humble, unedited photo of the Sun with a dramatically large sunspot group currently visible. I could even see the largest spot using the eclipse shades we used for observing the May 20, 2012 solar eclipse. Read all about it and see some very sharp photos at Spaceweather.com. Solar projection method with 60mm refractor telescope and 17mm eyepiece.

Below: Waning Crescent Moon at 5:37 AM CDT July 3, 2013 (10:37 UT). 8″ reflector telescope, 25mm eyepiece.

At the neighborhood park, at dawn on July 3:

Above: A mother Mallard and half-grown ducklings heading towards the water.
Below: I was very pleased to see a mother Wood Duck with eight ducklings!

Photos above with 7×35 Bushnell binoculars.

Above: It’s amazing how much wildlife one can see so close to the city, and you see more by coming out at a quiet time such as the early morning.

Below: A very calm dragonfly, no doubt looking forward to a fine day of mosquito hunting.

It’s good to get down to the neighborhood park again. Once I was there once or twice a day, but not very often for almost a year. The park is full of memory for me, the memory of two thousand walks with Pluto during the last two and a half years of his long life. But life goes on, new ducklings and all!

Supermoon! June 24, 2013

Lately the media have been heralding the occurrence of “Supermoons,” that is, times when the Full Moon coincides with perigee, the place in the Moon’s orbit when it’s closest to Earth. I’m happy to break over two months of non-blogging with the photo above, from this morning at 3:46 AM CDT (8:46 UT June 24, 2013). Compare with the earlier photos below, one taken at apogee (furthest from Earth) and the other at perigee, the especially “super” Supermoon of March 2011:

Above: 11:46 PM CDT October 11, 2011 (4:46 UTC), just 2 hours and 40 minutes after the time of greatest full phase. The Moon was 252,500 miles from Earth.

Below: March 2011’s “Supermoon,” 3:34 AM CDT March 19, 2011 (8:34 UTC). The Moon was 221,700 miles from Earth.

Don’t forget to look for Comet Pan-STARRS while it’s close in our sky to the Andromeda Galaxy!

Waning Crescent Moon April 3, 2013, with Lunar 100 #5: Copernicus; Saturn Update; and Comet Pan-STARRS Report

6:41 AM CDT April 3, 2013 (11:41 UT), 8″ reflector telescope with 25mm eyepiece.

The splendid crater Copernicus is Number 5 in Charles A. Woods’ Lunar 100 and can be easily seen in the photo above, and even more prominently in the upper center of this closeup from October 19, 2011, at 7:49 AM CDT (12:49 UT):

8″ reflector telescope, 25mm eyepiece, 2x Barlow.

It is a favorable time to view Saturn, as it is approaching opposition on April 28, at which time it will make its closest approach to Earth for this year. Here’s an update:

	5:56 AM CDT April 3, 2013 (10:56 UT) Angular diameter 18.57 arc seconds Distance from Earth 828,198,000 miles (1,332,855,000 km)
	6:45 AM CST February 21, 2013 (12:45 UT) Angular diameter 17.60 arc seconds Distance from Earth 873,809,000 miles (1,406,259,000 km)
	7:01 AM CST November 20, 2012 (13:01 UT) Angular diameter 15.49 arc seconds Distance from Earth 992,918,000 miles (1,598,000,000 km)
	11:42 PM CDT June 7, 2012 (04:42 UT June 8, 2012) Angular diameter 18.15 arc seconds Distance from Earth 847,415,000 miles (1,363,782,000 km)
	4:38 AM CDT April 12, 2012 (09:38 UT) Angular diameter 18.97 arc seconds Distance from Earth 810,707,000 miles (1,304,706,000 km)
	6:13 AM CST January 8, 2012 (12:13 UT) Angular diameter 16.82 arc seconds Distance from Earth 913,348,000 miles (1,471,501,000 km) 25mm eyepiece with 2x Barlow, scaled to match the others
	3:23 AM CDT April 14, 2011 (08:23 UT) Angular diameter 18.97 arc seconds Distance from Earth 810,570,000 miles (1,304,487,000 km)

Last but not least, I’m happy to report that on Sunday evening I made a clear sighting of Comet Pan-STARRS, which this week is passing right by the Andromeda Galaxy, so don’t miss it, because it’s one of the best times available to use a major astronomical “landmark” to find the comet! I don’t expect to post any pictures, as the comet is too faint for my modest photo equipment. but Nathan P. Hoffman succeeded in capturing it here, and a great place to watch for the latest amateur photos is www.spaceweather.com/.

Almost forgot – my photos are taken with an LG VX8360 cell phone camera, as usual. Gotta love the internet … a guy with no money can aim his pocket camera into a weathered old telescope and turn it into an astronomy site …

Waning Gibbous Moon (almost last quarter) April 2, 2013; Lunar 100 #4: Apennines; Christ is Risen!

Hello, folks, I’m happy to report that I still live on this planet!

The Moon hangs peacefully in the southern sky this beautiful clear morning. 7:40 AM CDT (12:40 UT) April 2, 2013, 60mm refractor, 25mm eyepiece.

I’m now resuming my post series on Charles Woods’ “Lunar 100”. Number 4 on the list is the Lunar Apennine Mountains, or Montes Apenninus, which figure prominently in the lower central part of this photo, which I took on July 10, 2012, at 5:14 AM CDT (10:14 UT):

8″ reflector telescope, 25mm eyepiece, 2x Barlow. Both with LG VX8360 cell phone camera.

Towards the north end of the Apennine range is Mons Hadley, notable because an adjacent valley was the Apollo 15 lunar landing site.

Happy Easter, and blessings to those who have recently celebrated Passover! This is what Easter is all about:

Saturn Update for February 21, 2013, with bonus sundogs and snowy trees

This post concludes my longest period ever without posting! Been busy, & the winter has been cold and snowy. But the northern winter has its glories, and here are a couple:

Above: Light, fluffy, delicate snow on tree branches, February 16, 2013 at 10:22 AM.
Below: Sundogs shining through the trees at 9:04 AM on the bitterly cold morning of February 19.

It was slightly hazy this morning, but it was so much fun to get out to the telescope again and observe Saturn, I went with it anyway. Here’s a Saturn series, similar in format to my Venus phase updates, beginning with this morning and working back through a few of my best Saturn photos. Note how over time Saturn’s rings are “opening up” as viewed from Earth. Unless otherwise noted, these photos are with the 8″ reflector telescope, 17mm eyepiece, and 2x Barlow:

	6:45 AM CST February 21, 2013 (12:45 UT) Angular diameter 17.60 arc seconds Distance from Earth 873,809,000 miles (1,406,259,000 km)
	7:01 AM CST November 20, 2012 (13:01 UT) Angular diameter 15.49 arc seconds Distance from Earth 992,918,000 miles (1,598,000,000 km)
	11:42 PM CDT June 7, 2012 (04:42 UT June 8, 2012) Angular diameter 18.15 arc seconds Distance from Earth 847,415,000 miles (1,363,782,000 km)
	4:38 AM CDT April 12, 2012 (09:38 UT) Angular diameter 18.97 arc seconds Distance from Earth 810,707,000 miles (1,304,706,000 km)
	6:13 AM CST January 8, 2012 (12:13 UT) Angular diameter 16.82 arc seconds Distance from Earth 913,348,000 miles (1,471,501,000 km) 25mm eyepiece with 2x Barlow, scaled to match the others
	3:23 AM CDT April 14, 2011 (08:23 UT) Angular diameter 18.97 arc seconds Distance from Earth 810,570,000 miles (1,304,487,000 km)

Happy New Year! Waning Gibbous Moon January 3, 2013

It’s 2013, the Earth is still here (no, I’m not surprised), so is the Moon, and so am I! Time to begin another year of low-budget, high-enthusiasm cell phone astrophotography!
