Alignment Check

5:13 pm CST, Saturday, December 24, 2022. 0.3 second exposure at f/2.8, ISO 200, 11mm focal length. Christmas Eve planetary alignment panorama, looking east (left) to west (right) from the grounds at Noelridge Christian Church in Cedar Rapids, Iowa: -1.43 magnitude Mars, -2.41 magnitude Jupiter (top), 0.81 Saturn, Moon, -0.28 Mercury and -3.91 Venus (just above tree). Air temperature was 6 degrees F, with wind chills around -20 degrees F. After just a few minutes out in the frigid elements, my body started to shiver uncontrollably--forcing me to high-tail it back to my nearby running vehicle to warm up, then emerge to go back out again. I had to do this twice. I was happy I was able to include all the visible planets (and moon) into a single panoramic image, because of my haste to get back to warmth!

                      Identical image from one at top, but with planet identifications. The planets Uranus, Neptune and the dwarf planet Pluto were also present, but too dim to see. Their positions are shown in this image as well. The following evening (Christmas Day) offered an even better alignment viewing opportunity for this location, but cloud cover and snowfall would prevent it. Nikon D7200 DSLR camera.

Blizzard Bluster

Talk of an impending blizzard with possible 10-15 inches of snow, 50 mph wind gusts and sub-zero temperatures in the days leading up to its arrival in Eastern Iowa had residents on edge. As weather conditions would play out in the days ahead, the blizzard was indeed potent, but not to the degree of some of the dire forecasts out there. The Radarscope image above shows the storm's progress at 3:41 pm CST, Wednesday, December 21, 2022, and again at 5:54 pm (below). The yellows and greens in Central Iowa show the more intense areas. The National Weather Service (NWS) issued a Blizzard Warning for Eastern Iowa on Wednesday evening, an upgrade from the previous issuance of a Winter Storm Warning.

8:23 pm. The image above looks west from Boyson Road at the Boyson Park trailhead parking lot during the early phase of the blizzard warning. The colorful streaks along the road at right are long exposure headlights and taillights. 10 second exposure at f/20, ISO 100, 24mm focal length. Air temperature was 21 degrees F.

Weather conditions for 8:36 pm.

9:00 pm. Looking northeast at Christmas lights on Timber Creek Drive, as seen from Boyson Road during the initial phase of the blizzard. 2 second exposure at f/9, ISO 100, 18mm focal length.

 

9:01 pm. Similar image. 2.5 second exposure at f/7.1, ISO 100, 30mm focal length.

Radarscope image for 8:03 am CST, Thursday, December 22, 2022. I had headed north of town to capture rural blizzard images. The image above shows that at this point most of the intense areas of snow (yellows and greens) had already passed east of my location (target icon).

8:04 am. Eastbound on County Home Road (E34), just west of North Marion Road/North Tenth Street, north of Marion, Iowa.

8:06 am. Looking south from North Marion Road, just north of County Home Road.

8:15 am. Looking north from the parking lot at Lowe Park in Marion, Iowa.

3:24 pm CST, Thursday, December 22, 2022. The skies had sufficiently cleared enough to allow this vivid sun dog to appear in the western skies. This image was captured from Alburnett Road in the Bowman Meadows housing development. Air temperature was -8 degrees F, with wind chills near -30 degrees F. My bare fingers instantly froze upon air exposure capturing this shot.

9:02 am CST, Friday, December 23, 2022. High winds and fast moving clouds did not prevent a morning sun dog from showing through. This image looks southeast over the Brentwood Drive NE neighborhood of Cedar Rapids, Iowa, as seen from Bowman Woods Park. Air temperature was -8 degrees F, with some wind gusts creating -40 degree wind chills. The snowfall in Cedar Rapids from the start of this storm on Wednesday was about 5 inches.

 

Nightfall in Cedar Rapids on December 23. Blizzard conditions continue with blowing snow. This image looks south from Brentwood Drive NE at 5:13 pm and is a (StarStax2) 5-image stack, with each image an 8 second exposure at f/11, ISO 100 and 18mm focal length. Nikon D7200 DSLR camera.

Sidenote: While standing outside to capture the Friday morning sun dog, I observed how high winds impacted the rear of houses along the eastern border of Bowman Woods Park. Snow carried along during high speed winds gusts visually showed how wind in open areas of the park (background and right) slammed unhindered into the back of houses, while houses downwind from where I was standing (foreground) were largely protected by the large hill (toward the left in this image). This provided a visual confirmation to the notion that houses protected by the hill survived the derecho winds of August 10, 2020 without much damage while those in open areas did not.

Acid Reflux Led Me to Ice Pillar Phenomenon Viewing

I woke about 12:15 am on Sunday, December 18, 2022 with an acid reflux-induced cough starting up. Rather than coughing in our bedroom I rose to do so in the kitchen. While in the kitchen I decided to step outside to check out the night sky. I gasped as I observed shafts of light all over the sky. My initial thought was an auroral storm was taking place, but curiously, my aurora alerts app showed nothing significant. It wasn't until about four hours later after my images had been processed and sent to the National Weather Service (in Des Moines, Iowa), that I was corrected and given the true nature of the event--Ice Pillars (also known as Light Pillars). Ice pillars are defined as optical illusions created from lights reflecting off the surface of horizontal ice crystals low in the atmosphere. These plate-like hexagonal shaped crystals are suspended in the air for a period of time, as is freezing fog. When the crystals get low enough in the atmosphere, they create the illusion of the ice pillars. Light sources that illuminate the crystals from below can be street lamps or other brightly colored lights over a city. The image above looks north over Bowman Woods Park in Cedar Rapids, Iowa at 12:43 am CST, and is a 5 second exposure at f/2.8, ISO 500, 11mm focal length. Ice pillar colors have been enhanced. Air temperature was 9 degrees F, with wind chills at zero.

12:45 am. Panorama looking north (center) over Bowman Woods Park. 5 second exposure at f/2.8, ISO 500, 11mm focal length. 

12:46 am. Similar image looking northwest.

12:52 am. Looking southeast over Brentwood Drive NE neighborhood. 8 second exposure at f/2.8, ISO 500, 11mm focal length.

12:56 am. Panorama looking northwest (center) from another area of Bowman Woods Park. Bowman Woods Elementary School is seen at lower left. 4 second exposure at f/2.8, ISO 500, 11mm focal length.

12:56 am. Looking northeast from same area. Ursa Major (The Big Dipper) can be seen at center.

1:00 am. Looking southeast over Brentwood Drive NE neighborhood. 3 second exposure at f/2.8, ISO 400, 11mm focal length. As it turned out, I was "fortunate" that my acid reflux allowed me to be awake for this event! By 3:00 am the pillars had mostly disappeared. 

7:45 am. Sunrise several hours later. A sun pillar is shown flanked by sun dogs as seen from the parking lot at Noelridge Christian Church. The hexagonal ice crystals were still present in the atmosphere to create this atmospheric light variation. Sun pillars (and moon pillars) are created in exactly the same way as ice pillars, but with the light of the sun or moon creating the shaft. Air temperature here was 5 degrees F.

Live Nativity Weather--Mild And With An Added Bonus

Noelridge Christian Church in Cedar Rapids, Iowa held its Live Nativity event on Wednesday, December 14, 2022--typically a time of year that is cold and snowy. Not so this year. Early evening temperatures hovered around 40 degrees F. An added bonus was fiery clouds in the western sky, enhanced by the sun from an open gap along the horizon. The image above was captured at 4:59 pm CST, an hour before the start of the Live Nativity event.

5:06 pm.

5:22 pm. Five shot stitched panorama image. Luminaries line the parking lot. 0.4 second exposure at f/3.5,  ISO 200, 18mm focal length. Nikon D7200 DSLR camera.

Moon/Mars Occultation---A Mini Eclipse

A double treat for sky watchers on the evening of Wednesday, December 7, 2022-- Mars occulting (passing behind) the full moon, and reaching opposition (opposite to the Sun in the sky and its closest approach to Earth). The occultation of Mars and the moon amounted to a "mini" eclipse--the red planet passed behind the moon and was hidden by it from 9:04 pm to 10:00 pm CST. Most of the day on December 7 was clear and bright, but a thin veil of clouds began forming just before the appointed time of the event. Because of this, I had to wait for the moon to emerge through brief cloud gaps to photograph it, and clear image captures were not possible. By 10:00 pm the sky had almost completely clouded over. The sequential image above is a composite of the occultation event, from 8:48 pm to 9:02 pm, captured from my back deck. Air temperature was 27 degrees F. Each image is a 1/80 second exposure at f/5.6, ISO 1000, 300mm focal length.

Before dawn on Thursday, December 8, a large portion of the sky had cleared. This image looks west at 4:06 am CST. Note the larger separation of the two celestial bodies at this point. Mars shone at magnitude -1.87. Air temperature was 23 degrees F. 1/400 second exposure at f/5.6, ISO 250, 240mm focal length. Nikon D7200 DSLR camera. 

This was the scene earlier in the day on Wednesday, December 7. The image looks northwest at 5:32 am CST from 33rd Avenue at 12th Street SW in Cedar Rapids, Iowa. The moon is partially obscured by shrouds of rolling fog, which was moving right-to-left in the image. iPhone 11 camera.

Mars Nears Opposition

The -1.84 magnitude planet Mars (center, just above tree line) sets in the western sky before the coming dawn as seen from Bowman Woods Park in Cedar Rapids, Iowa at 6:19 am CST on Saturday, December 3, 2022. The 0.06 magnitude star Capella in the constellation Auriga is seen at upper right. Air temperature was 13 degrees. Image is a 10 second exposure at f/4, ISO 400, 26mm focal length. The brightening Red Planet is approaching its December 8 date when it will be in opposition--its highest point in the sky and closest distance to Earth. This last occurred in January, 2007. 

Fast forward to Saturday evening. This panoramic image looks east (left) to south (right) over the Bowman Woods neighborhood of Cedar Rapids at 6:30 pm. Air temperature was 18 degrees F. 6 second exposure at f/2.8, ISO 250, 11mm focal length. Sky objects were: -1.85 magnitude planet Mars (just right of the large tree at left; the constellation Taurus (right of Mars); the star cluster Pleiades above Taurus; the glare of the moon (top); and the -2.57 magnitude planet Jupiter at upper right.

Frosty Window Feathers

 

This is how my passenger side car window appeared at 7:30 am on Sunday, November 13, 2022. The air temperature at the time was 19 degrees F. To create these shapes, water from the air lands on a really cold surface (in this case the window), and its molecules freeze and join together with other water molecules to form patterns of ice crystals. The hydrogen and oxygen atoms form a hexagon shape. If water molecules run into something like a speck of dust, salt or washer fluid, they may change direction and branch out into different feathery shapes. iPhone 11 camera.

Time for a Cool Change

 

Aftermaths in weather conditions influenced by cold fronts following warm spells in the month of November are considerably different from their summer counterparts. Such was the situation on Thursday, November 10, 2022. By midday, temperatures had risen to the low 70s. However, the threat of approaching storms moving about 35 mph along a cold front was expected to change the summer-like conditions dramatically. The image above looks northeast from 33rd Avenue and 12th Street SW in Cedar Rapids, Iowa at 2:09 pm CST. The advancing line of the storms can be seen on the horizon.

2:30 pm. Looking west. Line of storms (above) are not looking particularly structured or visually appealing despite looking rather impressive on radar (below).

2:38 pm. Rain, wind and lightning (and dropping temperatures) almost upon me. Temperatures had dropped to about 57 degrees by this time. 

2:46 pm. Looking northeast. Heavy rain (and temperatures) falling. By 8:00 pm this evening, temperatures had dropped to a chilly 40 degrees. Rain persisted through the night and changed to crusty ice by morning. By 9:00 am Friday, the temperature had bottomed out at 22 degrees F--almost a 50-degree difference in just 22 hours! iPhone 11 camera.
