The quick answer

Orionids ended on October 24, 2026. The next announced window is Leonids, November 14–19 local time; its core color remains unconfirmed in the reviewed sources. Green Core is the confirmed debut, and shiny availability is not confirmed.

Find the right field note

The catch guide explains the operational loop. The forms page separates seven-color artwork from the released color; the shiny page explains what has not been announced. Battle notes keep a moveset recommendation separate from a claim that Minior is a leading raid attacker.

What is available, and what is still unknown

Review date: October 28, 2026. The distinction between a published rule, a community data table and our editorial advice stays visible. No game account is connected to this site, and the guide cannot check your individual research or local spawns.

A practical catch plan

Before the next announced window, reserve bag space, check your ball and berry stock and choose a familiar route with ordinary access. Check the game’s own news for changes before travelling. During an active shower, use the 5–9 p.m. local encounter increase as a planning aid, not as a promise of a spawn at a particular stop.

On the encounter screen, observe the attack and movement pattern before throwing. Choose the ball and berry for the catch you want, then wait for a comfortable opening. Keep successful catches long enough to check their form and appraisal. This is general catch technique, not a measured Minior-specific catch-rate formula.

Color, shell and shiny are three different questions

Meteor is the rocky defensive appearance; an exposed core is the higher-Attack battle state described in the official announcement. That transition does not award a different core color. The seven colors are a collection question tied to release events, while shiny is a separate release status.

Do not treat a black-core image, a main-series screenshot or a selectable gallery preview as evidence of a shiny GO encounter. Keep a confirmed collector’s copy before deciding what to transfer, and compare actual game labels with the identification guide.

Pick a battle mode before spending resources

The existing PvP starting point is Rollout with Acrobatics and Power Gem, attributed to the reviewed simulation and move data. Treat it as a test candidate. Check current league eligibility, actual CP and how the game handles the new form transition before investing in a second attack or power-ups.

A database’s Rollout / Power Gem PvE recommendation compares Minior’s own moves. It does not establish live Core-form raid access or make Minior the best Rock attacker. The current GO Hub Core entry explicitly distinguishes its displayed damage model from raid eligibility. Use a team you can verify for the actual boss.

Keep three clocks on your checklist

The calendar is a planning tool. Research can have a separate claim deadline, and historical Orionids reports disagreed on that deadline. Read the account’s actual countdown rather than deriving it from the spawn window.

Frequently asked questions

Can I catch Minior after Orionids?

The next announced shower is Leonids, November 14–19, 2026. This guide does not establish ordinary between-event spawns or a repeat Green Core release.

Is shiny Minior available in Pokémon GO?

The sources reviewed for this guide do not confirm a shiny release or shiny odds. Artwork is an identification reference, not proof of availability.

Does Minior evolve or change core color?

Minior does not evolve. Its Meteor-to-Core battle transition is different from changing its core color.
