Image of Comet Holmes 17/P taken in the light pollution of the San Fernando Valley, near Los Angeles. It was photographed through the eyepiece of a 5 in. telescope (SCT) using one of my "running" cameras -- a 10 Mp compact digital.

An exposure of 60 seconds was used. The raw format image was pushed 2.5 stops and the tone curve adjusted in Adobe Camera Raw to bring out detail in the diffuse outer coma of the comet. The image was flipped so that it is not reversed and is upright.

The comet's nucleus is at about 8:00 o'clock, near the head of the more dense and bright inner coma. A hint of a tail can be seen projecting in the 2:00 o'clock direction. The tail of the comet isn't more obvious because from Earth we're seeing the comet almost head-on.

This illustration, generated using Starry Night Pro, shows the position of Comet Holmes 17/P on 11/13/07 - beyond the orbit of Mars - and its relationship to the Earth, Sun and the plane of the solar system. This NASA/JPL Java applet can also be used to show the orbit of the comet. (Use the scroll bars to change the orientation.)

From a run at Upper Las Virgenes Canyon Open Space Preserve (formerly Ahmanson Ranch).

The bright orange-red coloration of these immature large milkweed bugs (Oncopeltus fasciatus) is a warning to predators that they taste bad. Like monarch butterflies, they concentrate foul-tasting compounds from the narrow-leaf milkweed (Asclepias fascicularis) in their bodies.

Following several instars (molts), the nymph is transformed into the adult insect.

The photograph is from a run at Sage Ranch on July 23, 2007.

From Sunday's Cheeseboro Bound run. Exactly as found.

From a showery, twilight run in the Simi Hills.

Glistening in the morning sun, the wet trunk of a manzanita glows in iridescent shades of orange and red, pink and purple. Decorated with raindrops, the chaparral, and all within, breathe a deep sigh of relief. It has rained!

Prior to Saturday night's storm Los Angeles had recorded only 0.5 inch of rain in the last six months. Even by Southern California's arid standards, this is a meager amount.

Usually when there's an El Niño, wet Winter weather can be expected to develop in Southern California. But this year's El Niño has been a little quirky, developing later than usual, and becoming stronger than expected. So far this Autumn, the weather here has been somewhat quirky as well, with record setting high temperatures and below average rainfall. An El Niño, even a strong one, does not guarantee wet weather in our area. Whether or not the usual El Niño impacts eventually develop, we'll just have to see.

Another system is expected to produce some rain in Southern California this weekend, but in the last couple of days the computer weather models have been backing off the rainfall amounts. This morning's computer-based precipitation forecasts are nearly dry. Given the difficulty the models have had with this system, and the long fetch of moisture over the Pacific, maybe the forecast will change. For additional info about the El Niño and Southern California weather, check out my Southern California Weathernotes web site.

The manzanita photograph is from the Reseda to Trippet Ranch run described in my previous post, Musch Trail Mule Deer.

Fanged and clawed, death waits,
On a highland of lavender, near a saffron spire.

The silhouette of a crab spider on the petal of a back lit Purple nightshade (prob. Solanum xanti). The blossom is about 0.8 inch (~20 mm) wide, which would make the span of the spider's crab-like grasping forelegs about 0.25 inch (~7 mm). From a run at Sage Ranch Park on November 2, 2006.

Note: This is not a photo of Deadly nightshade (Atropa belladonna).

Tahquitz Peak Historic Fire Lookout

The intimidating canyon rose steeply above me. Towering rock precipices lined the canyon walls, their summits glistening in the morning sun. I was at an elevation of about 2600' and it was already warm. A little unsteady, and moving slowly at first, I started the ascent. Gaining speed, I passed the first rock face, and after a minute or two, turned to gaze at Palm Springs and the Coachella Valley. In what seems like a matter of minutes, yucca and cresote transitioned to mountain mahogany and juniper, and then to pine and fir. Suddenly my pace slows, there is a bump, a jostle, and a pause. The operator announces, "Welcome to the mountain station of the Palm Springs Tram. The elevation is 8516'..."

Mt. Baldy's North Backbone Trail is not a place to be in a thunderstorm. From start to finish it seems you are either on the crest of a ridge, or on or near the summit of a peak.

The photo above is of a spiral lightning scar on a Jeffrey Pine on the trail at the summit of peaklet marked 8555 on the USGS Mount San Antonio quad. The scar appears to be fresh, and could be from a strike that occurred this Summer. Perhaps the most remarkable thing, given the tree's prominent location, is that it hasn't been struck and scarred before.

The photographs are from Sunday's North Backbone Trail Revisited hike and run. A photograph of another Jeffrey pine that was struck by lightning can be found in the post Three Points - Mt. Waterman Loop.

A crop circle, Simi Valley style, from the Hummingbird Trail.

A totaled vehicle is an odd thing to find on a section of trail seemingly well away from any road.  In this case, Angeles Crest Highway (Hwy 2) is nearly out of sight and about a half mile up a very rough canyon. (Photo from October 23, 2005.)

Snow highlights skeletal fingers of chaparral burned in the 2003 Simi Fire. From the Chumash Trail in the eastern Simi Valley. More info and a couple of additional photos can be found in my Coyote Oak Journal entry Chaparral Snow.
