Observing sunspots from San Diego’s Balboa Park!

Sunspots on the surface of the sun were clearly visible today in San Diego! A sense of wonder filled me when I viewed the distant phenomenon from Balboa Park.

Today the Fleet Science Center had Sunspotter Solar Telescopes, solar binoculars and other instruments related to astronomy outside and ready for use.

I had stumbled upon a special event at the Fleet Science Center. They were hosting the NASA Community College Symposium, which would feature a planetarium show, educational talks, panels, and a variety of space-themed activities.

A recent graduate of SDSU’s Astronomy master’s program operated the solar telescope, and I tried to capture the tiny dark sunspots with my camera. (For my final photo, the image contrast was radically increased, bringing out the spots.)

What appear to be small spots on the sun’s surface can be up to 100,000 miles in diameter! The sun itself is about 93 million miles from where you stand!

Space Day amateur astronomers in San Diego!

Members of the San Diego Astronomy Association participated today in the San Diego Air & Space Museum’s 19th Annual Space Day!

The local amateur astronomers gathered on the grass of Pan American Plaza in Balboa Park, in front of the museum, and observed our sun through a variety of telescopes.

As I walked nearby in the late morning, I spied telescopes of every size pointed skyward toward the sun, which was still hiding behind “May gray” clouds.

I paused and spoke to several of these friendly astronomy hobbyists. Solar observation was their activity on this Space Day, and telescopes fitted with special filters could provide magnified images of sunspots, the sun’s corona and solar flares!

I was told how there are thousands of amateur astronomers around the country and world, and how their efforts often help to further scientific knowledge. When distant stars are seen to slightly wobble over time, or when their light’s intensity as seen from Earth periodically changes, it can be an indication that they are orbited by planets–exoplanets very far from our own solar system!

The members of the San Diego Astronomy Association possess an enthusiasm that is infectious. I could have spent half the morning absorbing fascinating information.

How can you not be excited, peering out into the awe-inspiring Universe–a vast, vast, incredibly vast Universe that includes the nearest star: our Sun!

The planet Mars vanishes in San Diego!

The planet Mars vanished from San Diego’s night sky early this evening!

Members of the San Diego Astronomy Association had telescopes trained on the Red Planet near the Fleet Science Center in Balboa Park when it disappeared!

But nobody seemed in the least distressed.

That’s because those gazing skyward understood the moon in its orbit around the Earth had begun to pass “over” much more distant Mars, in what is called a lunar occultation of Mars.

Random people walking through Balboa Park came up and were invited to peer through the telescopes. At times the instruments were aimed at the planet Jupiter and its four largest moons that were made plainly visible: Io, Europa, Ganymede and Callisto.

Families and kids looked into space with a sense of wonder. Many then entered the Fleet Science Center to view the monthly planetarium show The Sky Tonight, where we saw the latest jaw-dropping images from the James Webb Space Telescope.

When the presentation ended an hour later, and we all went outside, Mars had returned!

The next image was captured by my small camera a few minutes before the lunar occultation of Mars. I set it on maximum zoom.

You can’t see the moon’s craters, but you can see fuzzy little red Mars!

Gaze at infinite stars and beauty in Balboa Park.

Late this evening I took a stroll through Balboa Park. As the nodding, golden sun bid the blue sky farewell, a smattering of telescopes began to sprout under the brightening moon near the Reuben H. Fleet Science Center.

Today is the first Wednesday of the month. That’s the day members of the San Diego Astronomy Association gaze at stars and the universe’s infinite beauty, and invite casual passersby to gaze up at the wonders. Young and old bend over to peer through eyepieces, and are awed by the craters of the moon, planets that happen to be swinging overhead, colorful nebulae and distant galaxies…

The viewing begins in earnest around eight o’clock, when the sky is good and dark, right after the Reuben H. Fleet’s planetarium shows the monthly “Sky Tonight” program on their big IMAX screen.
