Use the event window and the daily boost separately
Minior is available through Pokémon GO’s Minior Showers, which follow named meteor showers. The first Orionids window runs from October 19, 2026 at 17:00 until October 24 at 23:59 in local time. October 21 falls inside that window. The official encounter is Meteor Form Minior in the wild; this is not a Nisu browser game or an encounter simulator.
From 17:00 to 21:00 each day during a shower, the announcement promises an increased chance of finding Minior and shooting stars in the in-game sky. That daily boost is shorter than the event. The announcement does not say encounters are impossible during the rest of the event, and it gives no exact spawn percentage.
If you can choose when to walk, plan around the boosted evening window. If you can only play earlier, distinguish a lower, unspecified chance from a claim of zero availability. Neither window guarantees a Minior at every PokéStop or within a fixed walking distance.
Local time follows where you play
The Orionids schedule uses local time rather than one global UTC start. A 17:00 start in Shanghai and a 17:00 start in New York refer to different moments. Do not convert the first city’s opening time and assume that every city opens then.
For an ordinary session, read the local calendar date and time where you are playing, then compare them with both windows. On October 24, the daily boost finishes at 21:00 while the announced event continues until 23:59. The last evening therefore has an unboosted period after the highlighted hours.
The in-game sky effect is a useful sign of the evening event atmosphere. It is not a separate astronomical observation requirement: the official instructions do not require clear real-world skies, seeing an actual meteor or traveling to a special viewing site. Use safe, accessible places where you would normally play.
One debut color now, seven across the rollout
The official announcement names seven core colors: red, orange, yellow, green, blue, indigo and violet. It schedules their debuts across several meteor showers. A picture containing all seven is an introduction to the collection, not evidence that all seven can be caught during Orionids.
For the current Orionids event, Serebii’s event record and Pokémon GO Hub independently list Green Core as the debut. The official announcement checked for this guide does not assign every remaining color to a named shower. We therefore leave those future color names unspecified instead of filling a calendar from the artwork.
The December Geminids have a specific regional distinction: one color debuts in the Northern Hemisphere and another in the Southern Hemisphere. That does not make every color a permanent country-exclusive Pokémon. It also does not promise that either hemisphere can catch both December debuts in the same local event.
Keep a small collection note with the core color, date and event where you obtained a Minior. Check the current event information before planning around a missing color. This page does not promise that changing battle form will recolor a Minior or unlock an unreleased color.
The announced annual shower calendar
The Pokémon GO team lists the following recurring local windows. Every listed shower begins at 17:00 on its first date and ends at 23:59 on its last date. The daily 17:00–21:00 increase applies during each shower.
From this October debut, the next named windows are Leonids in November and Geminids in December, followed by the May, July and August windows in the next annual cycle. The table records the published annual schedule. Check later event announcements for changes and exact color assignments before arranging travel or making a collection plan.
| Shower | Annual local dates | Color rollout stated in the announcement |
|---|---|---|
| Orionids | October 19–24 | One debut color; current event records identify green |
| Leonids | November 14–19 | Another debut color; not named in the checked announcement |
| Geminids | December 11–16 | Two debuts split between Northern and Southern Hemispheres |
| Eta Aquariids | May 3–8 | Another debut color |
| Southern Delta Aquariids | July 28–August 2 | Another debut color |
| Perseids | August 10–15 | Another debut color |
Meteor Form changes below half HP in supported battles
Minior starts in Meteor Form. The official rule says its core is exposed when health falls below 50%. Meteor Form has higher Defense and lower Attack; the exposed core has higher Attack and lower Defense. The threshold is below half health, rather than a promise that the form changes at exactly 50%.
At launch, this form change is supported while battling Team GO Rocket, team leaders and in GO Battle League. The announcement does not extend the same behavior to every raid, Gym or other battle type. If you are trying to observe the change, check the mode before deciding that the mechanic is broken.
A form rule is not a performance ranking. This guide does not publish an optimal moveset, IV target, CP jump or damage calculation from a single demonstration. The official announcement also excludes Minior from the 2027 Latin America International Championships, so ordinary GO Battle League support should not be read as blanket tournament eligibility.
Prepare a short session without buying for an unknown rate
Before heading out, check the local date, the current Pokémon GO event information and enough storage for catches. Choose an evening route you can use safely, and leave time to read the encounter result. These are practical preparation suggestions; Nisu has not measured how many Minior a particular route produces.
The official announcement says catching Minior awards increased Stardust, but it does not specify the amount in the checked text. Exact reward totals, timed-research tables and item multipliers are deliberately not reproduced here without primary confirmation. Read your own current reward screen before spending an item or making a purchase around a promised total.
If you do not find one, record whether you were inside the full event and inside the boosted hours. A short run without a spawn cannot establish that the species is unavailable for everyone. If the date is outside a listed window, check the next shower rather than assuming the daily evening boost runs all year.
Watch the announcement explained
Splendid Gaming’s October 2 video walks through the announced catch windows and form-change rules. We checked its discussion around 1:20, where the official schedule and battle text are visible. It predates the October 19 debut, so it is an announcement explainer, not footage proving current spawn rates.

A collector’s view of the color rollout
Tabapix’s October 15 guide discusses the staggered color collection and the hemisphere distinction. It is another pre-debut explanation, with creator opinions about collecting and battling. Use the official rules and current event screen for availability; the video does not establish a guaranteed catch or a battle ranking.

Quick help
Can Minior appear outside 5–9 p.m.?
The official text makes 5–9 p.m. a higher-chance period inside the longer shower event. It does not say Minior is impossible at other times during that event. No exact outside-window rate is given.
Can I catch all seven colors during the Orionids?
No seven-color availability is announced for Orionids. Colors debut in batches across the annual showers; current event records identify the first as Green Core. Geminids specifically split two debuts between hemispheres.
Does local time mean one worldwide release moment?
No. Use the dates and clock time where you play. For Orionids, the announced event is October 19 at 17:00 through October 24 at 23:59 locally; the daily boosted period is 17:00–21:00.
Why did Minior not change form in my battle?
First check the mode and whether its HP fell below 50%. The launch announcement only supports changes against Team GO Rocket, team leaders and in GO Battle League. It does not promise the mechanic in every battle mode.
Are the December colors different in each hemisphere?
Yes. The announcement assigns one Geminids debut to the Northern Hemisphere and another to the Southern Hemisphere. It does not name those two colors in the checked text.
Does this guide confirm Shiny Minior or the best moveset?
No. The checked official announcement does not provide a Shiny release commitment or a tested moveset ranking. Those claims need separate evidence; ordinary core colors are not a Shiny announcement.
Source and scope
Independent guide checked October 21, 2026. Timing, annual windows and launch battle limits come from the official Pokémon GO announcement; the current green-color identification is cross-checked against established event records. Community questions guide the hemisphere and form explanations, but speculative trades, animation timing and future reveals are not treated as confirmed mechanics. Nisu has not played or measured this event. Pokémon and official artwork remain with their respective owners; this guide is not affiliated with Pokémon GO.
