APRIL 2026
| 22–23 Apr | ★ Lyrid meteor shower | 15–20 meteors/hr; radiant rises after midnight; full-Moon phase does not interfere (waning gibbous sets pre-dawn this year). timeanddate.comastropixels.com |

Ongoing sky treats (any clear night)
- Milky Way core: Splendid in southern sky from May–August nights.
- Zodiacal light: Look for the pyramid-shaped glow before dawn in late September–October and after dusk in late February–March at mid-latitudes.
- ISS passes & Starlink trains: Use an app for real-time timings.
Anticipated comets & “wildcards”
| Comet | Best window | Notes |
|---|---|---|
| C/2025 L1 ATLAS | Nov 2025 – Apr 2026 | Could crest mag 12–13; circumpolar for N-latitudes in late winter. theskylive.com |
| C/2025 F2 SWAN | Late 2025 | Likely stays ~mag 14 (large telescope). theskylive.com |
| C/2025 J1 Borisov | Jun 2026 perihelion (3.6 AU) | Faint, but interstellar discoverer Gennadiy Borisov’s next gem—monitor with CCD rigs. theskylive.com |
Observing tips
- Dark skies: Get 40 km from city lights whenever possible.
- Moon phase matters: Use this list to plan meteor watching around new- or crescent-Moon dates.
- Safety first: For all solar eclipses, use ISO 12312-2 certified filters or indirect projection.
- Log your observations: Citizen-science networks (IMO, AAVSO) welcome timing, brightness, and photo data.
Clear skies and happy hunting—mark your calendars now so July 2025 through June 2026 becomes your most memorable astronomy year yet!
