Bringing Astronomy to the Sidewalk in Pasadena and Monrovia
11 years in Monrovia!
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.”
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. Join our email list using the link to the left.
That said, there are some patterns to when we can be found, and look at the top of the website for our next astronomy nights.
We typically set up telescopes 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.
August 2016 Perseids plus lots 'o planets In case you missed the January/February five-planet lineup in the dawn sky, you might have better luck this month. From August 4th through the 7th spot Venus, Mercury and Jupiter-and the moon-low on the western horizon about 45 minutes after sunset. On the 20th, the three planets make a pretty triangle five to ten degrees above the horizon.
Look in the south-southwest sky for a second planetary dance. Mars and Saturn are high and easy to see and are joined by the moon on August 11th.
The constellation Perseus is visible in the northern sky soon after sunset. And the famous and reliably active Perseid meteor shower peaks in the morning hours of August 12th. The moon, which paired up so nicely with Mars and Saturn on the 11th, is bright enough to blot out some of the meteors, but-lucky for you-it sets about 1 a.m. on the morning of the 12th, just at the peak time for the best Perseid viewing. Though you'll see the most meteors after moonset on Friday morning August 12th, the days on either side of the peak have elevated rates too, and even a week before and after the 12th you'll see some Perseids.
While waiting for the moon to set, and Perseus to climb higher in the sky, aim your binoculars at some of the beautiful nearby objects from within our Milky Way and beyond. The Milky Way's Perseus Double Cluster and the pretty globular clusters of Cassiopeia can all be spotted with the unaided eye. The Triangulum and Andromeda galaxies can also be spotted with the unaided eye, but binoculars and telescopes reveal more detail.
Here's August 2016 What's Up video. Perseids and Planets!
Jane's Favorite Things! To celebrate the one hundredth episode of ‘What’s Up’ in October 2015, I wanted to share some of my favorite celestial things. Here's the 100th What's Up video. Hope you enjoy watching it as much as I've had creating the series since 2007.
I'm creating a toolkit with NASA tools and resources to accompany each monthly video. These are for both armchair and amateur astronomers, sky loving students of all ages. Here's a peek at an early iteration of the Star Tool Box.
The Sidewalk Astronomers have a grand tradition of setting up telescopes in national parks throughout the year. 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 Mojave National Preserve, Joshua Tree NP, Bryce Canyon NP, Grand Canyon NP (north and south rims), and Glacier Point in Yosemite National Park.
Mojave National Preserve Spring 2016 Star Parties This is one of the darkest locations in the country, and it's the closest darkest location for those of us in southern California. The preserve invites their conservancy members and friends to camp under the stars at Black Canyon Group Campsite twice a year. Our May 7 spring star party was cancelled due scattered desert thunderstorms, but it's been rescheduled for June 25th. The fall star party date is November 5th. The campground is also reserved for the night of June 24th and November 4th, if you want to set up your tent, and enjoy the Preserve Saturday before the star party. Here's the 2014 fall star party flyer to give you an idea of what to expect.
For a taste of what it's like at a dark sky star party, this Yosemite Nature Notes video was filmed during three Glacier Point Star parties Jane, Mojo and Gary attended with the San Jose Astronomical Association. Our annual Glacier Point Yosemite Star Party dates are August 12-13, 2016, not a good dark sky night with a big waxing gibbous moon, but it is the Perseid Meteor Shower weekend. There are different astronomy clubs presenting free star parties at Glacier Point each weekend from July 4 through Labor Day (full moon weekends excepting), so if you are planning a Yosemite trip save a weekend night for Glacier Point!

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.
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!
