AstroVerde is the website of the Astronomers of Verde Valley.

 

Who Are We?

We are an amateur astronomy club serving the communities of the Verde Valley, Arizona. To learn more about us, click here

If you are as interested in Astronomy as we are, we hope you will  join  us at one of our star parties, meetings or guest lectures.

If you would like to become a member of AVV please use the contact information  below. We will be happy to assist you.

Here is the Club Brochure.

The Digital Collection

A new wave in astro photography is in process with the Astronomers of Verde Valley. Several of the members have acquired digital photographic equipment and are now busy taking and processing images. In the Digital Collection, more and more pictures will be updated on the site as time goes by.

Special Events

The Alamo Lake Night Under the Stars event was designated as an Arizona Centennial Event. (02/23/2012)

JD's Obsession

Iridium flare and Comet Holmes

Iridium 52 is the bright streak intersecting this shot. Comet Holmes 7P is above the satellite at the top of the page. The photograph was captured on December 12th, 2007, from Clarkdale, Arizona, by our very own JD Maddy and published in the UK's Sky at Night Magazine.

Iridium Gallery click here:  Iridium Flares

Equipment used: Pentax IST digital camera, 50mm lens at f/2.0 for a 30-second exposure

News Flash:

A young just under two day old Moon as it sets on Wednesday evening. The bright lower portion is illuminated by the Sun's direct light. The upper part is illuminated by the reflection of the Sun's light off of the Earth. Primarily in this case by the Pacific Ocean. This is called Earthshine. It can be easily seen as the Moon sets when it is only a few days old after the New Moon. The small star is HIP 19036. The Moon occulted the star a few minutes after this picture was taken, but a mountain got in the way of photographing it.

News Flash:

Asteroid Vesta and Asteroid Ceres are closing in on each other visually this summer. The pair are in the constellation of Virgo, not far from where Mars is visible. Even though they appear near each other, they will still be over 50 million miles away apart. Mid July will have them moving apart, but still very close. Check monthly astronomy magazines for accurate finder charts. Click picture for larger view.

 

Below is Nova Delphinus that was discovered on August 14th, 2013. It reached naked eye visibility before starting to fade. After nearly a year, it is still telescopically visible. Click the photo for a larger view.

 

The planet Venus made a two day pass by the Pleiades on April 2nd & 3rd, 2012. This pass was on the later of the dates. Click here for a full size image. The next near pass of Venus by the Pleiades will be on April 11th, 2015.

The Semi Annual Star Night at Kartchner Caverns is now in the books. The cool day and evening skies were wonderful. Over 450 observed thru the solar telescopes and the evening telescopes. Click the picture for more Kartchner pictures and other Outreach events. Click here for an infra red movie made from stills of the event.

 

Jupiter is setting quickly after Sun set this summer. A low western horizon is needed to see it after Sun set. The cloud bands and Galilean Moons are easily seen in small telescopes. Click to expand.

The Blue Horse Head Nebula in Scorpius is captured by member Mike Cadwell. IC 4592 as it is also known is 420 light years from Earth. To see more of Mike's photos, click here.

Club member Mike Cadwell is showcasing his astrophotography at the Sedona Library in the Villages of Oak Creek branch. The exhibit starts September 16th. Stop by and have a look at some of the beautiful things our universe is made of. Click the poster for a larger view.

Three Galaxies in Draco

Explanation: This intriguing trio of galaxies is sometimes called the Draco Group, located in the northern constellation of (you guessed it) Draco. From left to right are edge-on spiral NGC 5981, elliptical galaxy NGC 5982, and face-on spiral NGC 5985 -- all within this single telescopic field of view spanning a little more than half the width of the full moon. While the group is far too small to be a galaxy cluster and has not been catalogued as a compact group, these galaxies all do lie roughly 100 million light-years from planet Earth. On close examination with spectrographs, the bright core of the striking face-on spiral NGC 5985 shows prominent emission in specific wavelengths of light, prompting astronomers to classify it as a Seyfert, a type of active galaxy. Not as well known as other tight groupings of galaxies, the contrast in visual appearance makes this triplet an attractive subject for astrophotographers. This impressively deep exposure hints at faint, sharp-edged shells surrounding elliptical NGC 5982, evidence of past galactic mergers. It also reveals many even more distant background galaxies.

News Flash:

The second in at Tetrad of Lunar Eclipses will be on the morning of October 8th. This eclipse is also called a Blood Moon Eclipse as the Moon will be directly behind the Earth's shadow and will appear very dark red and maroon in color. The last of the Tetrad Eclipses will be on April 4th and September 28th 2015.

On the afternoon of October 23rd for most of the United States, there will be a partial solar eclipse. For the U.S., the Sun will be covered up to 80 % by the Moon.  Depending on your location, the Sun will be covered at least 30%. Check the link below for a map of the coverage and the times in Universal Times for the eclipse. You will need to adjust the time based on your time zone. I.e., Arizona subtracts 7 hours from UT. Map of eclipse.

Explanation: The Great Spiral Galaxy in Andromeda (aka M31), a mere 2.5 million light-years distant, is the closest large spiral to our own Milky Way. Andromeda is visible to the unaided eye as a small, faint, fuzzy patch, but because its surface brightness is so low, casual skygazers can't appreciate the galaxy's impressive extent in planet Earth's sky. This entertaining composite image compares the angular size of the nearby galaxy to a brighter, more familiar celestial sight. In it, a deep exposure, tracing beautiful blue star clusters in spiral arms far beyond the bright yellow core, is combined with a typical view of a nearly full Moon. Shown at the same angular scale, the Moon covers about 1/2 degree on the sky, while the galaxy is clearly several times that size. The deep Andromeda exposure also includes two bright satellite galaxies, M32 and M110 (bottom). This composite image is made from a stack of M31 images taken with a Celestron GPS11, Hyperstar 3 with a Canon 450D (XSI) and a single image of the Moon taken with the same setup.

Large Solar Flare Erupts

Click picture to super size.

Large flare erupts Nov. 18th, 2012.

A large solar flare decorates the Sun and it spews Hydrogen gas aloft. This flare was short lived and lost its detail in a two hour period. I call this a Serengeti Flare as it has the appearance of a tree on the Serengeti Plains. To see more solar pictures click here. To see the Annular Eclipse and Venus transit pictures, click here. For a look at a Serengeti Tree compared to the flare, click here.
