Jupiter Not Lost In The Wash This Night

Monday, April 30, 2018


Despite mighty planet Jupiter being 411 million miles from Earth on this night, it more than held its own in the light wash from our full moon on the night of Sunday, April 29, 2018. Above, -2.49 magnitude Jupiter (just above trees at bottom) shines gainly in the glow of our satellite--only 241,000 miles distant and -12.69 magnitude. This image looks SE from Bowman Woods Park in Cedar Rapids, Iowa at 9:29 pm CDT and is a 1/5-second exposure at f/5.6, 2000 ISO and 55mm focal length. Air temperature for photography was a mild 54 degrees F. Nikon D7200 DSLR camera.

Show Before the Snow

Wednesday, April 18, 2018


With knowledge of the forecast for a significant winter weather event the following day I was pleasantly surprised to find the skies over eastern Iowa clear on the evening of April 17, 2018. This was especially pleasing for the fact that a crescent moon and brilliant planet Venus would be in conjunction with one another just after sunset this evening. The image above, shot at 8:45 pm CDT,  looks west from Oliver Court in Marion, just south of Boyson Road and just west of Alburnett Road. It is a one second exposure at f/5, 400 ISO and 70mm focal length. Venus shone at magnitude -3.92 in chilly weather conditions which registered 38 degrees F with ENE winds at 10 mph or better.


I added Venus (right) to this zoomed-in image of the moon, and it appears much closer to its conjunction partner than it actually was. Both images were shot using the same settings: one second exposure at f/5.6, 400 ISO and 300mm focal length. Time was 8:47 pm. Note the Earthshine on the moon. Left and above the moon is the dim 4.12 magnitude star 5 Tauri. Nikon D7200 DSLR camera.


Snow, snow go away, come again some other...month!: The much anticipated winter weather system arrived here about 12 hours after the top images were viewed. The system came with rain, freezing rain, sleet and snow. Above, the wintry mass was well under way when part of it was captured at Bowman Woods Park looking south in Cedar Rapids at 3:18 pm CDT, Wednesday, April 18.


Radar screen capture of the system as it appeared around the time of the above image on Wednesday. The Cedar Rapids metro area received about one inch of snow when it ended early the next morning.

Xanto-ed Out

Sunday, April 15, 2018


On February 2 of this year what actually happened was this: The groundhog emerged from his burrow, saw his shadow, returned to his burrow, woke up again forgetting his first foray above, emerged again and saw his shadow for a second time--giving us 14 more weeks of winter. So while we're enduring that, Winter Storm Xanto, the back edge of a system that produced severe weather in the midsection of the U.S. last Friday, began wreaking havoc throughout much of the country's upper midsection--with snow and high winds. Above, the storm is shown in progress looking south on White Road north of Marion, Iowa, between N. Alburnett Road (W58) and N. Marion Road at 12:03 pm CDT, Sunday, April 15, 2018.


A similar view, closer to the ground, a minute later.


Same position, but looking east 12:05 pm.


12:11 pm. Looking south from White Road, about .4-mile west of N. Alburnett Road. Weather conditions were: snow, 32 degree F temps and 22 mph winds. Nikon D7200 DSLR camera.

I Was On My Way To A Global Warming Meeting But Got Stuck In The Snow...

Monday, April 9, 2018


...not really. But you get the idea. Unabated unseasonably cold weather gripped all of March and the first week of April in Iowa in 2018. Cedar Rapids saw 10 straight days of 40 degrees F or less up until April 9. The image above shows a snowfall event under way on Sunday afternoon, April 8, which did not end until the next day (another Cedar Rapids April 8 in 1973 comes to mind). This storm deposited just over three inches when it was all said and done. I placed my tripod in a shallow part of Dry Run Creek, which at this location is the border between Cedar Rapids and Marion, and faced south. The image is a stack combination (StarStaX2) of 14 separate exposures, all with identical settings: 8 seconds at f/22, 100 ISO and 16mm focal length using a 6-stop X2 77mm ND filter. Total elapsed time was 4:34-4:36 pm CDT. The water was not moving fast but the extended exposure allowed by the filter "calmed" the surface. On the down side, the exposure also "erased" the heavy snowflakes that were falling at the time.


Using the same settings as the top image but deciding to shoot only 8 separate exposures (4:46-4:48 pm) to stack is this image, which looks east at a footbridge a little further downstream.
