Comet NeEOWISE and the Big Dipper over Yosemite Valley

Here's a photo showing a slowly fading Comet NEOWISE C/2020 f3 below the Big Dipper. I was in Yosemite on the south rim next to Sentinel Creek with a clear view of the sky. I was hoping to get a view of the comet floating above El Capitan, but the moon was just past new and was setting so there was no light for the landscape. So I turned my attention to getting pictures of the comet with the Big Dipper so it would have recognizable stars around it. It's above two stars in the constellation Leo Minor. It's closest to the earth on this night, but farther from the sun so it's not as brighter as before.

ISO 6400, 30-second exposure, f4, focal length 20mm. This image was cropped to high light the constellation and comet below. 

Remember, it's not just a picture, it's a story!

Comet NEOWISE over Sacramento, California

These photos are of Comet NEOWISE, aka C/2020 F3, taken at about 4:39 AM Sacramento time on July 12, 2020. I, Bob, had driven to the west end of the Yolo Bypass, which is between the cities of West Sacramento and Davis, California. I was looking northeasterly when I took this shot.  Other photographers were out in these predawn hours to get photos of it, like I was. The horizon is the Sierra foothills.

At this point Comet NEOWISE is on the outbound part of its orbit after already whipping past the sun. The tails of comets are created by and directed by solar radiation, which means they always point away from the sun. The sun is below the horizon in this view and the tail is pointing away from it.

While I was getting shots of the comet, a freight train passed by me on the nearby tracks.

Remember, it's not just a picture, it's a story.

Great Fountain Geyser and forest fire smoke, Yellowstone National Park, Wyoming

This is a photo of the Great Fountain Geyser along the Firehole Lake Drive in Yellowstone National Park. This was taken on August 15, 2016 while a forest fire was raging on the horizon.  The smoke extends from the setting sun to the upper right corner.

Great Fountain Geyser is one of the geysers that the rangers can predict when it will erupt, but the window of time that it might erupt is plus or minus two hours. When it's building toward an eruption, the vent and surrounding terraces will fill with water to overflowing and the column of water will shoot up out of the pooling water, as opposed to geysers like Old Faithful Geyser that erupt out of a cone.

Remember, it's not just a picture, it's a story.

Female common mergansers resting on a log, American River Parkway, Sacramento, California

We were out paddling around the American River Parkway in Sacramento, California when we encountered these female common mergansers resting on this log that had fallen across this channel.  This is just downstream from the Watt Avenue Bridge.

The merganser in the middle had its mouth open, while the merganser on the right was giving us the eye while trying to get some sleep.  Mergansers are also known as fish ducks, since they feed on small fish by diving underwater and swimming after their prey.

Remember, it's not just a picture, it's a story.
