Solar Eclipse, 8 April 2024

| edwinridout

We had our weekly Zoom chat April 7th. Gareth said “Today’s clear sky was great for eclipse photo dry runs… Spent hours fussing with cardboard filter-adapters and such.” He’s the only one of us living in the Zone of Totality.

Sandy and I weren’t in the zone of totality, and we’d heard we’d only get about an 86% eclipse. We sat on the porch for the duration. Assuming only 14% of sunlight, we’d expected our afternoon to get much darker than the slight reduction we experienced. Another puzzle for me was it seemed as though the moon didn’t cross the sun in a straight line. It entered the sun from the lower right, seemed to move straight right-to-left, then veered upwards and departed from the top middle. (Somebody living only a few miles from us made a Facebook post showing exactly how we saw the eclipse.) Gareth thought if we’d viewed the eclipse at noon from the equator, then the path might have been straight.

We had a few days at the beach in early August. We all rode bikes, we walked, some of us went running at sunrise, we sat on the beach, played in the sand, ate and drank. Wore plenty of sunblock and needed lots of insect repellant for the wildlife refuge. No sunburn or shipwrecks and nobody drowned. We also saw a big NASA rocket launched (see separate page). Various photographers. You can hover on the edge of a photo to a show description and pause the slideshow — then un-hover to resume the slideshow.

Rahier’s Column Clock

From the Belmont newsletter at GariMelchers.org:

“After an absence of nine months, Gari and Corinne Melchers’ thirty hour long case clock work has returned from the clockmaker’s repair shop. Mr. Mark R. Pellman of Ashland, Virginia performed the repairs, aside from the micro-welding of the gears which had to be sent away. The beautifully incised pewter face was fashioned by a craftsman named Rahier from Eupen, Belgium, as inscribed. The face is not original to the works behind it, nor are either the face or works original to the long case. The case was probably made in the 19th century in Holland or Germany, while the works and face probably are one hundred years older.”

Neabsco

Woodbridge, Virginia

From the Neabsco Creek Boardwalk, we’re looking southeast 1.3 miles to the railroad trestle at the creek’s mouth with the Potomac River. The Maryland shoreline is barely visible above the bridge, an additional 3.5 miles beyond. That would be the southwest tip of the Indian Head Peninsula. The newly opened $4 million 3/4-mile boardwalk is a pedestrian delight, open dawn until an hour after dark. We saw a couple of egrets but only at a distance, a few redwing blackbirds, and we heard more than we saw numerous tiny chattering birds. Will have to return at a more opportune hour. The only bird I caught on camera was almost as big as a crow but I don’t know what it was yet. [Nick must be right: a crow.] I was of course pleased to catch the southbound CSX freight train through my big lens.

The red marker (top, middle) is where we parked and entered the Neabsco Boardwalk on foot. My orange ink highlights the boardwalk winding 3/4 of a mile across the wetland. The orange line at lower right is the aforementioned railroad trestle, to the right of which is the Potomac River. The as yet unrenamed Jefferson Davis Highway shown on the left is the old main road south to Key West (1,300 miles) or north to Montreal (650 miles).
