METEOR SHOWERS

the twelve principal showers of the year · periods, peaks and ZHR per the IMO calendar

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

Formats: A4 · A3 · A2
What you get: Print-ready PDFs, one per size, with every letterform converted to outlines — nothing to install, nothing to shift.
Subject: astronomy · everyone · reference · study

Data — International Meteor Organization, “2026 Meteor Shower Calendar”, Table 5 (imo.net; read 08.2026): periods, peaks and ZHR verbatim. Peak dates are exact for 2026 and drift within a day from year to year. ZHR assumes ideal skies; real counts are lower.

THE RICHEST SHOWER OF THE YEAR ISN’T THE AUGUST ONE

The Perseids are the famous ones — warm nights, holidays, headlines. Yet the IMO working list gives them 100 meteors an hour and the December Geminids 150. The richest shower of the year simply freezes without an audience.

And July 31 is the year’s only double peak: the Southern δ-Aquariids and the α-Capricornids max out on the same day, from the same patch of sky — observers tell them apart by the speed of the meteors.

Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
Nothing about how it was made: the sheet carries only what the reader needs.

Printing

Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
White background and sparing fills — it prints on a home printer without draining the cartridge.
Margins of at least 10 mm: a home printer cannot print to the edge.
No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 7 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
