Land o’ Goshen! Saturday, 260103
Sunrise: 8:10 a.m.
Sunset: 5:25 p.m.
Last night’s Goshen low: 25°F (-4C)
High today 23°F (-1C). Predicted low tonight 21°F (-11C).
I missed two days of posts, but each day’s sunrise and sunset times are on the PDF chart below.
Cold today, then rain this week. Then back to snow and cold, wintry weather.
One egg today, again from the Alpha Chick. (1 in prior two days, also from the Alpha Chick.)
Low level of earthquakes worldwide. The usual scatter of small quakes—upwards of twenty minis in southern Alaska, five to ten each in California and western Texas. The Big One has not yet hit California.
Oh, and a huge one in Venezuela, but figuratively with the criminal arrest of “el Presidente” Maduro.
3I/Atlas the comet is leaving town; no goodbyes, so sorry ET fans. And Messiah is yet to return.

[The pdf file displays sunrises and sunsets from 251203 to date.
The rate at which sunrise has been getting later has slowed to zero, apparently. Since I can track it only in whole minutes, I can only estimate the exact date that sunrise is at its latest, and starts to get earlier. Let’s see whether the middle point of all these zero-change sunrise times is as far from the middle-point of shortest daylight times as is sunset.
Sunset has been getting later since December 7th/8th. This was two weeks before the official Solstice (12/22),. Now the change increases by one (rounded) minute eight of the last ten days. The rounded daylight length increased by one minute today, to 9:15. The length of day (sunrise to sunset) has been increasing over nine days, so by this measure we passed the Winter Solstice, at or near the middle of the string of the shortest daylights (9:09), on 12/21.
Both sunrise (maybe, still) and sunset are later each day, though sunrise seems to be zeroing out. If you are familiar with sine curves, both sunrise and sunset are following sine curves, but they are not identically timed, or “synchronous”, or “in phase.”
I still don’t see why the sunrise keeps getting later, though, if we have passed the Solstice—and why it is zeroing out, which means it is at or near its latest time four weeks after sunset zeroed out (inflected).
Are you graphing?
If you’re graphing or tracking, I am curious to know whether your local inflection points match those in Goshen, Indiana. Drop a comment if you’d like. The times vary by longitude, of course, as the sun “travels” from East to West. The times vary with latitude as well, since the farther north you go the later the sunrise and earlier the sunset until Winter Solstice. What I’m most curious about is whether those inflection points—the dates when the sunrise switches from getting earlier to getting later, and sunset switches from getting earlier to getting later—should be the same everywhere; and maybe that will give a clue why the sunrise and sunset times do not switch on the same day....
Revolving-Door Vertical-Axis Wind Turbine (VAWT)
Where is the problem? Insufficient our overly turbulent air flow? Sticky or high-friction turbine? Poor bearings? Poorly designed inlet and/or outlet air funnels? Poorly executed inlet and/or outlet air funnels? Wrong ratios? Which ones? My next steps are to remove the turbine rotot, check the bearings and the housing, and re-mount it.
I think a pair of high-velocity 12-inch fans directing air into the wind tunnel will provide a better air flow than the single 18-inch fan directing air at the 12”x24” wind tunnel opening, so if cleaning up the turbine rotor doesn’t resolve issues, I might have to invest another $100 to $200 to get a pair of fans discharging at least 5 or 6 m/s (meters per second), about 10 mph.
It sure is complicated making something so simple! I understand better what Thomas Edison meant when he said that genius is 1% inspiration and 99% perspiration.
