Worldwide astronomical events

AMS and NASA list 16–17 November for the peak night. This does not forecast a meteor storm. Check the radiant height before dawn, moonlight and the hourly forecast for your location. A worldwide planning date cannot predict your observed count.

AMS and NASA list 13–14 December as the peak night. An evening opportunity may be available where Gemini is already high enough, but the geometry differs with latitude. Check local darkness and the Moon before choosing a start time.

AMS lists the night of 21–22 December. The shower has a far-northern radiant and is not equally useful worldwide. Read the current annual prediction and check the Moon before setting a watch. The entry is a broad night, not a precise peak instant.

The December solstice brings the Northern Hemisphere toward its longest nights and the Southern Hemisphere toward its shortest. High southern latitudes can have continuous twilight or daylight. The instant is an orbital marker, so use your location for the actual observing window.

AMS and NASA list 3–4 January for the peak night. The short maximum makes the year-specific prediction and your local dark hours important. Check the current source closer to the date rather than treating a date-only calendar download as a precise appointment.

Annularity follows a limited path across parts of South America and the Atlantic. Other locations may have a partial eclipse or none. Use the linked NASA maps and local circumstances. Annular phases always leave bright Sun visible and require suitable solar protection.

The Moon passes through the lighter part of Earth’s shadow. Dimming can be subtle rather than the strong colour change of a total lunar eclipse. Local dates can span 20–21 February. Check the NASA circumstances and whether the Moon is above your horizon.

The March equinox marks the start of astronomical spring in the Northern Hemisphere and autumn in the Southern Hemisphere. It is a global orbital event, not a special target that becomes visible at the listed instant. Local daylight and night length depend on latitude.

At review, AMS lists 21–22 April while NASA lists 22–23 April for the 2027 Lyrid peak night. This calendar therefore marks a planning window across 21–23 April rather than inventing one exact hour. Recheck the current annual prediction before travelling; the Moon, cloud and radiant height still control the local view.

AMS and NASA list 5–6 May for the peak night. Southern tropical locations can have better radiant geometry than far-northern ones. Check the interval before local morning twilight, the Moon and cloud. A wide unaided-eye view is appropriate for watching.

The June solstice brings the Northern Hemisphere toward its shortest nights and the Southern Hemisphere toward its longest. At high northern latitudes, astronomical darkness may be absent. The instant is global; it is not the local time of sunrise, sunset or the warmest day.

The totality path crosses parts of southern Europe, North Africa and the Middle East. Outside that path, the eclipse can be partial or absent. The date alone is not a local contact time. Use official path maps, local circumstances and current solar-viewing guidance.

This is a penumbral event, so the visible change can be slight. A local calendar may label the night 16–17 August. Use the linked NASA data to check the event phases against your Moon altitude rather than expecting a dramatic total-eclipse appearance.

The September equinox marks the start of astronomical autumn in the Northern Hemisphere and spring in the Southern Hemisphere. The listed UTC instant is shared worldwide, while the calendar date on a local clock can differ. Use a location forecast for the actual twilight window.
