Astronomical Events Calendar 2026: When to Look at the Sky?
Astronomical Events Calendar 2026 is a quick “what and when” guide to the night sky: meteor showers, moon phases, eclipses and seasonal phenomena such as noctilucent clouds (NLC). Below you will find a lightweight LIVE widget with a countdown to the next event and a month-by-month calendar.

2026 sky calendar – month by month
| Month | Most interesting events | Links and planning |
|---|---|---|
| January | Quadrantids (meteors) – short peak. | Check meteors + compare with moon phases. |
| February | Annular solar eclipse – mainly outside Europe. | Eclipses (visibility and safety). |
| March | Total lunar eclipse (not visible from Poland) + good dark-sky windows around new moon. | Moon phases – hunt for dark nights. |
| April | Lyrids (meteors) – moderate activity. | Meteor calendar. |
| May | Eta Aquariids (meteors) + start of the NLC season. | Combine NLC with dark skies. |
| June | NLC season (often the best nights) + very short nights in Poland. | How to hunt NLC. |
| July | NLC + summer observing windows (depending on latitude). | In the background check the aurora radar. |
| August | Perseids + total solar eclipse (track: Iceland–Spain) + difficult lunar eclipse late in the month. | Perseids + eclipses. |
| September | Longer nights and better observing conditions. | Plan with moon phases + watch the aurora. |
| October | Orionids + the aurora season grows with longer nights. | Aurora radar + meteors. |
| November | Leonids – usually moderate, but historically spectacular. | Meteor calendar. |
| December | Geminids – one of the strongest showers of the year + long nights (great for aurora). | Geminids + aurora radar. |
January 2026 – Quadrantids and the start of the year under dark skies
At the beginning of the year, the key event is the Quadrantids, a short but sometimes intense meteor shower. It is a good moment to compare the dates with moon phases and plan your first dark-sky trips of the year.
February 2026 – an annular solar eclipse outside Europe
In February it is worth tracking the annular solar eclipse, even though the main visibility is outside Europe. It is also a good month to visit the eclipses page if you want to know where and how to watch similar events safely.
March 2026 – a lunar eclipse and darker nights around new moon
March 2026 brings a total lunar eclipse, although it will not be the best show from Poland. It is still a useful month for hunting darker nights and comparing dates with the moon-phase calendar.
April 2026 – the Lyrids and a spring meteor shower
In April the Lyrids, one of the best-known spring showers, take the spotlight. It is a good month to check the meteor shower calendar and plan observations for the night of 21/22 April.
May 2026 – Eta Aquariids and the start of the NLC season
May 2026 combines the Eta Aquariids with the beginning of the noctilucent-cloud season. It is a transitional month in which you can combine meteor watching with the first attempts to catch bright structures low over the northern horizon.
June 2026 – NLC and the brightest nights of the season
June is usually one of the best months for NLC, despite very short nights in Poland. If noctilucent clouds interest you, this is when it is worth checking the northern horizon most often and combining observations with the weather forecast.
July 2026 – NLC, summer observing windows and a chance of aurora
In July the NLC season continues and, under favorable conditions, it is also worth glancing at the aurora radar. It is a more seasonal than single-event month, but still important for people following summer sky phenomena.
August 2026 – Perseids and the total solar eclipse
August 2026 is the strongest month in the entire calendar: you get the Perseids, the total solar eclipse of 12 August 2026 and a partial lunar eclipse at the end of the month. August should be one of the most prominent months on this page.
September 2026 – longer nights and the return of better observing conditions
September does not bring one giant event like August, but it does bring increasingly long nights and better conditions for planning observations. It is a good moment to combine moon phases with the first autumn nights and aurora watching.
October 2026 – the Orionids and the start of a stronger aurora season
In October it is worth watching for the Orionids while returning to regular checks of the aurora radar. The long nights become more and more favorable, especially outside large cities.
November 2026 – the Leonids and preparation for winter peaks
November 2026 is the month of the Leonids and the transition into the winter observing season. Although they are usually not as spectacular as the Perseids or Geminids, they are still worth keeping in your calendar and comparing with the weather.
December 2026 – the Geminids and long nights for aurora and meteors
At the end of the year the key event is the Geminids, one of the strongest meteor showers, plus very long nights favorable for observations. December 2026 naturally closes the season for people following both meteors and the aurora.
How to plan sky observations
Dark sky and the Moon
For meteors and subtle phenomena such as NLC, the nights around new moon are crucial. You can check dates on the Moon Phases page.
Weather and transparency
Even the best calendar is useless under full cloud cover. In practice, hunt for cloud breaks and high air transparency, especially when tracking aurora.
Weather and cloud cover (Windy)
Before you head out, check clouds and visibility in Windy, especially for meteors and subtle sky phenomena.
Safety: the Sun
For solar eclipses, use only certified filters. Details and visibility from Poland can be found on the Eclipses page.
