[Ads-l] Not in OED: tracklet (astronomy)

[George Thompson]

>From the NYTimes, an article about studying astronomical photos of the
stars, looking for asteroids:
Astronomers call a series of observations of a single moving object during
a single night a “tracklet.” A tracklet provides an indication of the
object’s motion, pointing astronomers to where they might look for it on
another night.

The on-line article is Killer Asteroids Are Hiding in Plain Sight. A New
Tool Helps Spot Them.  It deals with an attempt to recognize asteroids that
appear in a single photo, and therefore didn't create a tracklet.

A version of this article appears in print on May 31, 2022, Section D, Page
1 of the New York edition with the headline: Using Math to Spot Hidden
Asteroids.

But when aroused at the Trump of Doom / Ye shall start, bold kings, from
your lowly tomb. . .

The Trump of Doom -- also known as The Dunghill Toadstool.  (Here's a
picture of his great-grandfather.)
