Summer ushers in the beginning of meteor-watching season
d
There is something quite peaceful and humbling about a star-filled sky on a clear, moonless night. Adding the flash of a streaking meteor is like the final note of a captivating symphony.
There are big and little meteor showers throughout the year, but I consider summer the beginning of meteor season because the evenings are warm and pleasant, the brilliant Milky Way hangs in the night sky and it’s just more pleasant to be outside.
Unlike many activities, there is nothing more than a folding chair or blanket required to become a full participant, so pack a picnic dinner, head out to a dark sky location and enjoy the view.
One of the brighter annual meteor showers is the Perseids arriving next month. Tiny bits of debris from the Swift-Tuttle Comet will enter our atmosphere, producing up to 100 meteors per hour for several nights, peaking on the night of Aug. 12-13. This year a bright moon will unfortunately make viewing a bit more difficult than it would be on a moonless night.
Because of the quality and number of meteors, even casual observers put the Perseid shower on their annual calendar. The 2018 display should be spectacular because there will be nomoon. Anza-Borrego Desert State Park is one of the best night sky viewing locations, but temperatures in August can be punishing even at night, so you might consider other locations such as Palomar Mountain or the higher elevations of Cuyamaca of Mount Laguna.
The next major shower will be the Orionids that extend from Aug. 25 through Nov. 19, peaking on the night Oct. 22. There are fewer meteors produced by the debris of Halley’s Comet, but viewers this year should have a great show because there will be no conflict with the moon.
A month later, the Leonids peak on the night of Nov. 17-18, producing up to 15 meteors per hour. Mountain temperatures will be a bit cooler, so this will be a good time to head to the dark sky of Anza-Borrego where the New Moon will not interfere with viewing.
December will bring this year’s most spectacular show when the Geminids brightly flash through the dark sky, peaking on Dec. 13-14 at the rate of up to 120 meteors per hour.
The Geminids are considered one of the most reliable displays, radiating from a location high in the night sky by 9 p.m.
Meteor showers have odd sounding names because they are identified by where they seem to originate. The Perseids seem to radiate from the constellation Perseus, the Orionids from Orion, the Leonids from Leo the Lion, and the Geminids from the constellation Gemini.
There are dozens of smartphone and tablet apps available
to help viewers locate constellation and other celestial objects in the night sky.
Other above average meteor showers will continue with the New Year, including the Quadrantids in January, Lyrids in April, and Eta Aquarids in May.
What, exactly are meteors?
Because of the sometimes- bright fireballs created as this cosmic dust burns up in our atmosphere, many think meteors are larger objects. In actuality, most are nothing more than grains of sand that ignite when slamming into Earth’s atmosphere at a speed of 40 miles per second. The extremely bright meteors may be caused by something as large as a pea.
On any given night you are likely to see random flashes of light as meteors burn up entering our atmosphere, and there are minor showers nearly every month.
But you don’t need a meteor shower for an excuse to enjoy the spectacular night sky. If you are really into discovering the outdoor world, there is much to explore once the sun goes down.
There are satellites moving through the heavens, and a whole different world of animals that you may encounter.
I once had a curious kit fox quietly approach me as I sat on the Borrego Sand Dunes watching the night sky. Nighthawks, owls, coyotes, skunks, raccoons, geckos, tarantulas and other creatures are more active at night.
There is more to the great outdoors than a mountain hike, great fishing trip, birding or exploring the desertwilderness. The night sky is another opportunity to sit and see.
A few quiet hours sitting under a sparkling night sky will allow you to discover more than you ever imagined.

Soft whispering of quail a sign property has come a long way A male quail being a lookout. (ERNIE COWAN) ERNIE COWAN  Outdoors I could hear the whispers and it sounded juicy. If only I understood quail. It was an intimate moment with nature like I had never experienced before. Sitting motionless at the edge of the flowerbed I was listening in to the whispered conversations of feeding quail just a few feet away. The murmurings were hushed, almost inaudible. I’ve written before about the “muttering army” of quail that pass my bedroom window at dawn as they emerge from native cover and march to a nearby seed feeder. Their not-so-subtle cooing then is an almost daily alarm clock. This was the same sound, but I could almost not hear it. Had there been a wind or other noise the sounds would have vanished. The feeding quail were obviously close to each other with no need to be speaking loudly. This became an impromptu sit-and-see moment. I was out enjoying the morning sun and had pulled u...

  Birds will head to Mexico for the winter By  ERNIE COWAN While the civilized world seems to struggle in turmoil right now, the natural clock of ages faithfully ticks on. As another August slips from the calendar, the beat of nature goes on, and the happy visitors to my summer garden are hearing the call to launch them on a journey south. We can’t hear this call, but the hooded orioles do, and they are eagerly preparing to return to some preordained place in Mexico for the winter. These beautiful birds have added color, sound and joy to Mt. Whoville, as they have for thousands of other bird lovers throughout Southern California who provide food, water and nesting sites. A week ago, I began to notice fewer brightly colored males, and this week the males are gone. This is typical, with males leaving first, followed by females and the late-crop juveniles. For the past few weeks the orioles have been feeding aggressively at the nectar feeders, quibbling and cackling as they alway...

ERNIE COWAN  Outdoors It was a wildlife encounter I can only describe as profound. I’ve photographed desert bighorn sheep many times over 50-plus years, but this adventure was one I will never forget. The summer heat was withering as I stepped from my vehicle in Anza-Borrego Desert State Park. Not only were temperatures well into the triple digits, but it was slightly after noon so there was no mercy from the pounding midday sun. I came with high hopes of finding bighorn sheep in one of the desert canyons that has perennial water. These isolated sources of water are a thin lifeline for the animals who live in this arid place. The air temperature alone was bad enough, but I could feel even more heat radiating off the light-colored desert sand as I followed the dusty trail. Movement caught my eye. A jackrabbit? They are not typically active in midday summer heat. I stopped on the trail and suddenly a massive desert bighorn ram pushed through a thicket of...
