ENTRY 001 // ORION 21:04 UTC

THE HUNTER RISES OVER THE BATTLEMENT HORIZON

FILED OBSERVER 07   ■   AZ 112°   ■   ALT 41°

At twenty-one-oh-four, Orion cleared the eastern wall of the observatory courtyard. The three belt stars — Alnitak, Alnilam, Mintaka — were captured as a single square of amber ink against the cream of the night. Seeing was listed as four of five; the atmosphere breathed gently, stars held still. The Great Nebula (M42) was visible to the unaided eye as a faint pixel of sage green on the Hunter's sword.

Noted: a faint meteor tracked north-to-south through the Hunter's shield at 21:17 UTC. The parchment was marked in copper.

ENTRY 002 // CASSIOPEIA 22:31 UTC

THE QUEEN ENTHRONED IN THE NORTHEAST CORNER

FILED OBSERVER 04   ■   AZ 034°   ■   ALT 62°

Cassiopeia held court in the northeast quadrant, her zig-zag throne clearly drawn against the cream of the Milky Way's edge. Schedar burned amber; Caph flickered in a rhythm we have begun to suspect is atmospheric rather than intrinsic. The W-form inverts to M each night as the sky wheels — a reminder that the archaic sky is never still, only patient.

An uncatalogued faint companion sits roughly 3 arcminutes from Ruchbah. It will be recorded in the catalog below and observed again on Night 413.

ENTRY 003 // URSA MAJOR 23:47 UTC

THE GREAT BEAR STALKS THE UPPER MERIDIAN

FILED OBSERVER 01   ■   AZ 318°   ■   ALT 58°

The Plough hung high and handle-down, pointing its two end-stars toward Polaris with the indifferent precision of a bored courtier. Mizar and Alcor resolved cleanly, a pair of amber pixels nested inside one another — the classical eyesight test, passed for the four-hundred-and-twelfth consecutive night.

A thin cirrus band drifted through the bear's shoulders just before midnight, turning each star into a small soft halo of graphite against cream.

ENTRY 004 // ARCHAIC-VII 01:12 UTC

THE SCRIVENER, AN INVENTED CONSTELLATION, VERIFIES ITS OWN SHAPE

FILED OBSERVER 07   ■   CLASS ARCHAIC   ■   IDX VII

This shape is not ancient. It was drawn by our predecessors in the year of the second great fog, when the sky was invisible for eighty-one nights and the star charts had to be reproduced from memory. The eight stars of ARCHAIC-VII are real; the lines between them are ours. We keep the Scrivener in the catalog to remember that every constellation was, at some point, an invention.

Tonight, the Scrivener held its hand unusually steady. A good omen, by our own definition.
