I find it rather assimilating 🤡

A year and a half ago, 2024-06-06, we went over Catalog Number 59999. Yesterday, we passed 66999, meaning we have less than 3,000 catalog numbers left. At the rate for the last 1,000 (55 days), we have 165 days left or until 2026-05-24. Time is quickly running out to prepare.

"Ravens that refuse to sing", "Black Crows", "Birds flying high, You know how..." (and of course the protagonists from the BBC 2008 film trailer Miracles of Evolution). Assumed true Spheniscidae excluded from competition, otherwise poll weren't necessary.

This is exactly why my multiexposure of the eclipse last night still had an overlap — since I had completely neglected lunar motion around Earth in a 128 sec gap estimate. Mun moves on orbit 3% the length of its body-dia in the meantime. Andrew's pic is brilliant, just wonder why shadow static(?)

Or /iow: waiting longer btw the Moon shots makes the disk 'move' further to the up right b/c camera on Earth has rotated further (24h/day), but at the same time the Mun also had a slight shift to the left on its 28d-journey around Earth. Hence, relative rotation appears 3-4% slower than 2π/24h. 2/2

Nerd-fact: I had roughly estimated from lunar diameter, distance, +Earth rotation that 130s would be just enough to get clear lunar 'disks':
128s=atan(dia/dist)/(2π/24h).
But I neglected lunar counter rotation around Earth, which adds a few seconds to the bill. That's why the disks overlap a bit 1/2

So you are saying the enforced d(TWS)/dt — instead of ET + Q — temporarily balances a grand part of the P? 🤭
(rather runoff/surface flow than Q...)
