We plan to be on the sidewalk tonight (Saturday, 06/20) with targets of the Moon, Venus and hopefully Jupiter if it is not too low. Sunset is just after 8 pm as summer is upon on us (officially starting 06/21 at 1:24 am PDT). We hope you stop by! Dave Hasenauer For the Old Town Sidewalk Astronomers

Ttonight's (03/28) sidewalk astronomy evening at the corner of Myrtle & LIme - NEW INFORMATION
by David Hasenauer 28 Mar '26

28 Mar '26

Sadly, currently 9 out of the 10 predicative weather app models that I use are predicting much thicker clouds tonight than they previously predicted (through at least 9 pm, perhaps later). We will monitor the skies but unless there is a really big improvement, our original plan to be on the sidewalk tonight (Saturday, 03/28) may not happen. If so, sorry about that, and we will hope to see you next month on April 25th under better skies.

Telescopes in Monrovia Canyon Park Tonight (Friday 03/27) & our regular monthly sidewalk night tomorrow (Saturday 03/28)
by David Hasenauer 27 Mar '26

27 Mar '26

Hi, Just a reminder about two upcoming events. The Old Town Sidewalk Astronomers have teamed with the Monrovia Parks Department for Community Stargazing from Monrovia Canyon Park. Tonight is the last session. Here is the flyer: [cid:9d0cec63-0c5c-4b00-8b1d-694c9645d6ce] There is no cost for the event above, but you do need to register. Rather than the general city website on the flyer, to register go to: https://secure.rec1.com/CA/monrovia-ca/catalog Click on the "Canyon Park" tab, and the registration link is at the bottom. Alternatively, you can call the number on the flyer. Note that we don't know how many have registered so far, so if they are at capacity and cannot accept additional reservations, our apologies. However, all is not lost since we will be at our usual corner of Myrtle & Lime tomorrow evening after sunset (~7:10 pm). We hope to see you out and about, and "looking up" * The Old Town Sidewalk Astronomers

International Observe the Moon night this Saturday!
by David Hasenauer 21 Feb '26

21 Feb '26

Hi Everyone, Saturday is "International Observe the Moon" night! The Old Town Sidewalk Astronomers plan to be out at the southeast corner of Myrtle & Lime (Library Park), weather permitting. Astronomy enthusiasts worldwide will all be looking up. You can be part of the party too by either observing the Moon from home, or join us on the sidewalk! Both the nearly Full Moon and Saturn will be available to our telescope, but they both need some time to clear the trees and buildings after the 6:30 pm sunset. So the starting time may be around 7:30 to 8:00 pm. We hope to see you there! Dave Hasenauer For the Old Town Sidewalk Astronomers

Sidewalk astronomy for February
by Jane Houston Jones 03 Feb '26

03 Feb '26

Hi everyone! This month the Old Town Sidewalk Astronomers are featured in a display of astro people, places and things related the night sky at the Monrovia Canyon Park Nature Center. The exhibit opened Sunday February 1st and will be on display for a couple months. It’s really lovely! You can find info on parking and maps and so forth on the park’s website https://www.monroviaca.gov/your-government/parks/canyon-park#ad-image-0 The Sidewalk Astronomers at Monrovia Canyon Park Nature Center Three things for February: 1. There is an expected sidewalk astronomy event on Saturday, Feb. 21, at Monrovia’s Library Park, Myrtle and Lime Streets, weather permitting. There are also some events at Monrovia Canyon Park on Feb 27th, and at the Library on March 21st. More on March events next month! 2. Groundhog day = Cross Quarter Days. Did you know February 2 marks the halfway point between the Winter Solstice and the Spring Equinox? This celebration was observed by the ancient Celts who called this celebration Imbolc. The other cross quarter days are May 1, known as Beltane, August 1 known as Lammas, and October 31, known as Samhain. I love that ancient knowledge and culture have continued to our present time on Earth. And I like this explanation from the Old Farmer’s Almanac. https://www.almanac.com/quarter-days-and-cross-quarter-days 3. NASA’s What’s Up video. I’m so happy to report that the What’s Up video which was created in 2007 is still being produced by JPL and NASA. That’s almost 20 years. It’s NASA’s longest running video series! Here’s the February 2026 episode: https://science.nasa.gov/solar-system/whats-up-february-2026-skywatching-ti… That’s all for February. Feel free to ask questions, let us know events you are interested in reading about. Over and out!
