The latest What's Up
Bringing Astronomy to the Sidewalk in Pasadena and Monrovia
Visitors to Old Town Pasadena enjoy views of the first-quarter moon through Jane's 12.5-inch reflector telescope.Being a Sidewalk Astronomer isn't really about “joining” anything — it‘s about embracing a philosophy and acting on it.
Ask John Dobson how he became interested in astronomy, and he‘ll answer, “I was born!” People have a natural fascination with the Sun, Moon, planets, and stars, but to most it‘s something they read about in a magazine or see on television.
We stop people on sidewalks and let them see the craters of the Moon, the moons of Jupiter, the rings of Saturn, or the spots on the Sun. For just a moment, they have a personal connection with the universe around them, and sometimes life seems a little better after that.
We call it “urban guerilla astronomy.”
What's Up home page from JPLUpcoming Events
Many of our sidewalk events are planned only a few hours in advance. We will send a notice to our events email list on an afternoon when we plan to be observing.
That said, there are some patterns to when we can be found.
We typically set up telescopes in Pasadena on Colorado Blvd. somewhere between Fair Oaks and Pasadena Ave. on Friday evenings, and in Monrovia at Myrtle and Lime on Saturday evenings. For us to set up telescopes, the sky needs to be clear, there needs to be something to see (Moon, Jupiter, or Saturn), and we need to be available that evening.
Weather is always a factor. Our telescopes, big as they are, can not see through clouds. On an evening when we plan to be out observing, we will generally give it a try if there is a better than even chance that we'll get to view the Moon or planets. Occasionally a thin layer of haze will make the sky appear overcast, but the Moon will still show through.
There is never any charge to look through our telescopes.
April and May 2012 highlights
April: Watch Venus in the west and Mars and Saturn in the east this month. Saturn rises at sunset and sets at sunrise. It's at opposition - closest to Earth on the 15th, heralding the middle of the best viewing months for the ringed planet. Get out to dark skies on the 21st or 22nd. You may see some Lyrid meteors! This is a great month to see the galaxies of spring. Join up with a local astronomy club at a dark sky location and catch some galaxies. On the 22nd, look very low on the western horizon and catch Jupiter next to a thin crescent moon! On the 23rd look for the Moon near the Pleiades, on the 24th Moon and Venus, and on the 30th moon near Mars. These are all pretty views with your eyes, through binoculars, or try to capture the view using your camera! Your Old Town Sidewalk Astronomers may be heading out to a dark site on the 14th and/or 21st of April. Let us know if you are interested in tagging along. We typically drive 150-200 miles away from LA light pollution, and we car-camp on BLM land or an asphalt parking lot after observing most of the night, and sometimes have a morning hike, or find a local diner for breakfast. Ride share and share the gas cost with a friend.
May: More moon and planet pairings this month. Look for the moon near Saturn on May 3 and 4. On May 20, lucky observers will witness an annular solar eclipse. Viewers from S. China to Japan to N. California and on to North TX will see the ring of the sun around the moon's dark silhouette. This is the first central (total or annular) eclipse to cross the US since 1994! Since our semi-annual Mojave National Preserve star party is May 19, Mojo and I plan to get up early and drive as far north as we can before about 5 p.m. Eureka, Red Bluff, Redding and Reno are on the eclipse centerline. The annular eclipse begins 6:30 p.m. and will last 4 minutes, 47 seconds. On the 21st, look for the moon below Venus. It's next to Mars on the 28th and below Saturn and Spica on the 31st. Spring is galaxy time at the telescope, but you have to get far from city lights to see any. That's why we'll be at the Mojave National Preserve in May

The Sidewalk Astronomers have a grand tradition of setting up telescopes in national parks over the summer. For many urban dwellers, an excursion to a national park is the only opportunity to see the Milky Way for themselves. A sky full of stars can be staggering to someone who lives under the L.A. light dome.
We love to get away from the city lights, and love to invite park visitors to spend a little quality night time under a star-filled sky with our telescopes. Jane and I love to set up our big telescopes in Joshua Tree, the Grand Canyon, and especially Glacier Point in Yosemite National Park.
Mojave National Preserve: One of the darkest locations in the country, and the closest to those of us in southern California. The preserve invites the public, and their conservancy members to camp under the stars at Black Canyon Group Campsite twice a year. Mojo, Jane and Gary (probably more) from your Old Town Sidewalk Astronomers will be there September 24th. I'll put a link for the RSVP as soon as I have it. I's free but there is limited room for campers, so RSVP is necessary. Until then, pencil in this date if you are interested in free campsite (limited room for RV's too). Great hikes during the daytime, plus shared potluck before dark. This website will be updated soon.
Yosemite: One of the "best-kept secret" events at Yosemite National Park during the summer is the weekend star party at Glacier Point, high above the Yosemite Valley. The park invites a different club from Northern California to bring telescopes each weekend that isn't near a full Moon. Club members get a free campsite for the weekend, and park visitors get a free star party. Mojo, Jane and Gary from your Old Town Sidewalk Astronomers will be there August 26-27. Attend as a visitor if you'd like!
For a taste of the Glacier Point star parties, visit Mojo's photo album from 2002 with the San Jose Astronomical Association. If you plan to visit Yosemite National Park in the summer, consider an evening at Glacier Point on a Friday or Saturday evening. Bring warm clothes and a picnic dinner, and enjoy the setting sun as it lights Half Dome from the stone amphitheater. Most clubs present a short slide talk on astronomy, and the ranger will do a constellation talk out at the point. Bring a flashlight to help see your way along the trails, but cover it with your hand so you get only as much light as required.
Grand Canyon: Every June for a week, visitors to Grand Canyon National Park are able to enjoy beautiful telescope views and astronomy talks at the annual Grand Canyon Star Party. Astronomers travel from across the country to set up on both the North and South Rim visitor areas. It'll be held in 2011 from June 18-25.
Bryce Canyon Astronomy Festival, Utah: June 2007 was our first visit to this fabulous event. It'll be held in 2011 from June 29-July 2. Follow this link for more information.
Joshua Tree: During the winter season, we're delighted to join the Andromeda Society of Yucca Valley, California, for their dark sky star parties in Joshua Tree National Park. Star parties are held in the Hidden Valley Picnic Area, easily accessible from the entrance gate in Joshua Tree, north of the park.

Jane Houston Jones and Morris "Mojo" Jones
Jane Houston Jones and Morris "Mojo" Jones at the Glacier Point star party in Yosemite National Park.Meet our fellow astronomers here
Jane and Mojo have been setting up telescopes on sidewalks ranging from Hawaii to Florida since 1990. As amateur astronomers, they've participated in meteor observing missions for NASA, and appeared on national TV and radio programs.
Jane and Mojo kept the Sidewalk Astronomers active in San Francisco, the birthplace of the worldwide Sidewalk Astronomers, until relocating to Southern California in late 2003. They immediately saw the potential of Myrtle Avenue in Monrovia as the perfect location for sidewalk astronomy, and bought a home there in January 2004.
Among their list of awards and accomplishments, minor planet 1992LE was designated 22338 Janemojo in their honor.
Jane works for the NASA Jet Propulsion Laboratory in Pasadena managing public outreach and informal education for the Cassini-Huygens Mission to Saturn and Titan.
Mojo is a software engineer at Fox Audience Network, and operates his own internet server for friends and family as a hobby.
Telescopes for Schools and Educational Functions
Drop us an email if you would like to have the Old Town Astronomers bring telescopes to your school or civic event. Contact us to discuss dates that are best for informal astronomy in the city. As a guideline, dates near the first-quarter Moon are the best early-evening astronomy. Don't forget to consider the time for sunset!
