SUMMARY:Lyrids Meteor Shower Peak
DESCRIPTION:Best seen from Northern Hemisphere\, with a lower hourly rate in the Southern Hemisphere\, Lyrids seem to stream from the Constellation Lyra. They actually derive from the debris trail of Comet C/1861 G1 Thatcher\, which has a period of 415 years. Can be “fireball” bright but usually lack persistent trains\, they travel ~49km/second and have a maximum rate (ZHR) of 18 per hour.

SUMMARY:Quadrantids Meteor Shower Peak
DESCRIPTION:The Quadrantid shower is known for its brief\, intense peak\, lasting only a few hours. Appearing to radiate from Constellation Quadrans Muralis\, there can be 25-120 meteors per hour. Comets are traveling ~40km/second and come from the debris trail of Asteroid 2003 EH1\, discovered in 2003 by the Lowell Observatory Near-Earth Object Search (LONEOS). Meteors are often bright and colorful. If there is a Full Moon\, only the brightest will be seen\, reducing visible meteors to ~10 per hour. Best seen from Northern Hemisphere.

SUMMARY:Orionids Meteor Shower Peak
DESCRIPTION:One of 2 showers yearly from Halley’s Comet dust\, one dust cloud from Halley’s path toward the Sun\, and one from its path away. Orionids appear to radiate from Constellation Orion\, are swift (~67 km/sec)\, and can be bright and leave persistent trains. Between 10 and 75 meteors per hour are visible\, an amount that changes from year to year depending both on atmospheric particles and phase of the Moon. Orionids are active from Oct 2 – Nov 7\, 2025.

SUMMARY:Draconids Meteor Shower Peak
DESCRIPTION:Appearing when Earth passes through the tail of Comet 21P / Giacobini-Zinner\, the comet was a perihelion in 2025; speculation has arisen this may be a year with peak yielding many hundreds per hour. However\, the Full Moon the day prior may compromise viewing. Most years show 10-20 per hour\, appearing in Constellation Draco\, near stars Eltanin and Rastaban in the head of the dragon. Draconids are active Oct 6-10\, 2025.
