Aurora Enthralls Locals and Photographers
Recently, Borrego Springs was treated to a rare and spectacular sight—a geomagnetic storm brought the aurora borealis into view, captivating locals and photographers alike. Here’s a recap of the event and what made it so special.
The Nights of May 10th and 11th
The sky above Borrego Springs lit up with vibrant auroras, a rare occurrence for this region. The National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC) had predicted a powerful G4 storm, and it did not disappoint. Residents and photographers gathered in dark areas away from city lights to witness this celestial phenomenon.
The Science Behind the Show
The awe-inspiring display was caused by a series of coronal mass ejections (CMEs) from sunspot region 3664. This massive sunspot, fifteen times the diameter of Earth, had been particularly active, launching multiple CMEs toward our planet. These CMEs combined to create a powerful "cannibal" CME, resulting in the stunning auroras visible as far south as California and Alabama in the U.S.
What causes the aurora?
"In a nutshell, the magnetic field that comes along for a ride in the blast of particles released in a CME, couples with Earth's magnetic field. This creates a conduit that funnels those particles — electrons and protons — at high speed into the atmosphere over the planet's polar regions." ~ Source:

Capturing the Moment
Photographers in Borrego Springs took advantage of the clear skies and dark locations to capture the auroras. Equipped with cameras and tripods, they documented the colorful light show, sharing their photos with the community. The auroras displayed a range of colors from pale greens to vivid reds and purples, a sight usually reserved for more northern latitudes.

By Dennis Mammana Week of March 8-14, 2026 If you hear the word "superstar," what immediately comes to mind? Perhaps names like Tom Hanks, Taylor Swift or LeBron James? That's certainly understandable; they are all undisputed superstars who attract the attention of paparazzi and fans alike. If you're an astronomer, however, you may answer this question differently. For example, when I hear the word "superstar," I think of UY Scuti, WOH G64 or RSGC1-F01. Yes, these are superstars, but not quite how people may think. These are some of the largest stars known in our galaxy and, for that reason, are quite intriguing to us celestial paparazzi. Regular readers of this column know that our sun is also a star. It appears big and bright in our daytime sky because not only is it rather close (about 93 million miles away), it's also pretty large (nearly a million miles across). It sounds huge, but our star is rather small on a cosmic scale, and believe it or not, there are stars out there that would dwarf our sun and make it look tiny. These are the true superstars! Until recently, the largest star known was given the hopelessly poetic name of UY Scuti. At a distance of some 9,500 lightyears from Earth, UY Scuti is what is known as a red hypergiant star, with a diameter some 1,700 times that of the sun! All that changed recently, however, when astronomers found a gargantuan star some 2,150 times larger than our sun! It's named Stephenson 2-18, and if you'd like to get a peek at this stellar behemoth, you'll need more than your eyes. At a distance of some 18,900 lightyears, it appears 5,100 times fainter than we can see without a telescope. If you have no telescope but would still like to see a celestial superstar, you're in luck. There's one shining in our night sky right now; it's one of the brightest up there and is named Betelgeuse. Betelgeuse sparkles brightly in the northeastern corner of Orion, the hunter, and you can see its orange light midway up in the southern sky after dark this week. With about 15-20 times more mass than our sun, Betelgeuse is known as a red supergiant star for good reason. While we could align 109 Earths across the face of our sun, we would need at least 700 suns to cross the face of Betelgeuse! Indeed, this star is so immense that if it replaced our sun at the center of our planetary system, Betelgeuse would engulf the orbits of Mercury, Venus, Earth and Mars, and stretch part of the way to Jupiter! Yet it appears as a simple point of light in our night sky because of its tremendous distance from us — some 3,100 trillion miles, or about 520 lightyears. Betelgeuse is easily one of the largest known stars, though its size fluctuates by as much as 60% as the star shudders and pulsates on its way to an eventual supernova explosion, thousands or millions of years from now. Or tonight. We just don't know. I hope you'll step out under the night sky soon to meet this remarkable superstar for yourself! Visit Dennis Mammana at dennismammana.com.

By Dennis Mammana Week of March 1-7, 2026 Attention, night owls and insomniacs! The sky show this week is just for you! Much of North America is about to see the moon experience one of nature's most beautiful sky shows: a total lunar eclipse. A lunar eclipse occurs when the full moon slips into the Earth's shadow far out in space, either partially or completely, and that's just what will happen during the wee hours of March 3. Skywatchers throughout North America will see the start of this eclipse (weather permitting, of course), but depending on where you live, you may see only a portion of the sky show. In general, the farther west you live, the more of the eclipse you will see before the moon sets behind the western horizon. The eclipse begins at 12:44 a.m. PST (3:44 a.m. EST), when the moon enters the Earth's light outer shadow (known as the penumbra), but this shadow is so thin that no one will notice a darkening of the moon's appearance. Within an hour or so, that will change significantly. As the moon approaches the dark inner shadow of the Earth (known as the umbra), skywatchers will notice the eastern side of the moon beginning to darken slightly. The real show begins at 1:50 a.m. PST (4:50 a.m. EST) when the moon officially enters the umbra. No one gazing skyward will have any doubt that a "bite" has been taken out of the moon — a bite that will grow larger with each passing minute. For the next hour or so, the moon will dim as it slips more deeply into our planet's umbra, until 3:04 a.m. PST (6:04 a.m. EST) when it's completely engulfed and the total eclipse begins. Unfortunately, those in the far eastern part of North America may miss this since the moon will lie quite close to (or even below) the western horizon. During the total phase, the moon will take on a dim coppery hue. This occurs because sunlight passing through our atmosphere is reddened and bent inward toward the darkened surface of the eclipsed moon, now suspended eerily against the stars of Leo, the lion. Only those viewing from the Midwest to the West Coast will see mid-eclipse, which occurs at 3:33 a.m. PST (5:33 a.m. CST). Those in the Midwest may miss the end of totality at 4:02 a.m. PST (6:02 a.m. CST), however, as the moon will be setting in the west. The entire event will end at 5:17 a.m. PST (4:17 a.m. MST) with the moon approaching the western horizon for viewers in western North America. Unlike an eclipse of the sun, a lunar eclipse is perfectly safe to view without protective filters. Your eyes are all you need to enjoy the show, but you'll have even more fun viewing through binoculars or a small telescope. If the sky is cloudy that morning, or if you live where the eclipse won't be visible, you can watch a livestream of the sky show online.

Exploring Bailey's Cabin in Anza-Borrego’s Upper Coyote Canyon Tucked away in the remote Upper Coyote Canyon, within the vast Anza-Borrego Desert State Park, lies Bailey's Cabin—a historic gem that invites both adventurers and history enthusiasts alike. A Glimpse into the Past Bailey's Cabin was constructed in the late 1930s or early 1940s, likely by the Larner Brothers after acquiring the land from Jim Wellman. Originally used as an outpost for cattle ranching, the cabin has withstood the test of time, serving as a shelter for countless adventurers over the years. The cabin’s stone walls and simple amenities offer a stark contrast to the harsh desert environment, providing insight into the life of early settlers in this rugged landscape. The Journey to Bailey's Cabin Reaching Bailey's Cabin is an adventure in itself. By vehicle, the only route is via the "Turkey Grade," a road that can be treacherous, especially after rain. For those on foot, horseback, or bike, access is also available from Lower Coyote Canyon, offering stunning views and the natural sounds of the desert. Remember to check with Anza-Borrego State Park for updated road conditions and trail closures, as the area is periodically closed to protect bighorn sheep.
