Learning

Mnemonic
Link LYRA (the constellation) + IDS (like in 'meteorids' or 'asteroids'), so 'Lyrids' are the meteors from Lyra.
Conceptual Metaphor
CELESTIAL FIREWORKS (a natural, predictable light display).

Frequently Asked Questions
The Lyrids are active annually from about April 16th to 25th, with peak activity typically around April 22nd.
They are caused by Earth passing through the debris trail left by Comet C/1861 G1 (Thatcher).
They are a medium-strength shower, usually producing 10-20 meteors per hour at peak under ideal dark-sky conditions, though rare outbursts have occurred.
In British English, it's typically /ˈlɪrɪdz/ (LI-rrids). In American English, it's commonly /ˈlaɪrɪdz/ (LYE-rids), reflecting the pronunciation of the constellation Lyra (/ˈlaɪrə/).
