It's officially summer in Southern California, and the warm evenings ahead are perfect for taking in the night sky. Today is also the start of the seasonal, free Star Parties at Griffith Observatory that run from June through September.
If you go, you might meet local amateur astronomer, Spencer Soohoo. By day, he’s a research scientist at Cedar Sinai but in his off time, he’s an active member of the Los Angeles Astronomical Society.
We asked Soohoo for some advice on how to get into amateur astronomy in Southern California — if you’re already into stargazing — how to up your game.
Getting started
To kick us off, we asked Soohoo to recommend a few places where the stars may be easier to spot:
- Joshua Tree: He says the national park "is starting to get a little more light pollution now than before but it's still fairly decent."
- I-5 near Frasier Park: "There's a couple of turnouts you can go to."
- Saddleback Butte State Park: Soohoo has this caveat: "There's a lot of light now from the Lancaster-Palmdale area. But the last time I went, you could still see the Milky Way without too much trouble."
- For really dark skies: You have to drive a distance, probably about an 1 1/2 to 2 hours away.
Not up for that drive? Soohoo says "to be honest with you, if you're OK with looking at the planets and some of the brighter nebula, you can even do that from downtown L.A."
What can you see in SoCal this time of year?
Soohoo says right now the only night object "really prominent" is Venus.
"If you are up around maybe midnight or 1 a.m., you can see Saturn and Jupiter will rise a couple hours after that," he says.
How to spot planets
We asked Soohoo what he'd recommend folks use if they want to know where the constellations and planets are specifically in the sky.
Soohoo says his favorite smartphone app is Sky Safari ("I think it's about $9 to $10") but there are other free apps to check out.
"They're tied into the GPS in your phone and they'll show you what the sky looks like at that particular time," he says. "Some of them have what they call augmented reality. So they'll actually use the camera on the phone and superimpose the background of what you're seeing along with the sky chart."
Will the northern lights be back in Southern California?
Recently and unexpectedly, people were able to catch a glimpse of the northern lights exceptionally far south. So we asked Soohoo if that's going to be possible over the summer months.
He doubts it.
"It's rare that you'd be able to see them this far south," he says. "But I know that the last time you could see the northern lights from Mount Wilson — that one night that they were visible — the marine layer had moved in and blocked out all the light pollution from downtown L.A. and so you could see the northern lights there."
What to expect at Griffith Observatory
Griffith Observatory hosts monthly star parties during the summer that are free to the public. Volunteers from telescope groups and the L.A. Astronomical Society are there and Soohoo says participants can expect 25 to 40 telescopes to be set up on the grounds.
"We basically set up our telescopes on the lawn and point them at whatever target we want to and invite people to look through them," he explains. "And I personally focus on the moon because you'd be amazed at how many people have never seen the moon through a telescope in their lives. I can't tell you how many languages I've heard people say, 'Wow, it's just incredible.'"
Soohoo said he got his "greatest thrill" from helping an 82-year-old woman who had never looked through a telescope in her life.
"I showed her the moon and just to watch the expression on her face as it lit up — that's why we do it," Soohoo said.
