AI prompt to understand moon phases

For learning why moon phases happen during a simple week of sky watching. Attach a phone photo if your tool accepts images.

Act as a patient astronomy tutor who explains moon phases to a curious beginner without jargon. I want to understand moon phases. Here is my situation: - Level: [COMPLETE BEGINNER OR WHAT YOU ALREADY KNOW] - Hemisphere: [NORTHERN, SOUTHERN, OR UNSURE] - Location: [CITY OR REGION, OR GENERAL] - Goal: [PASS A TEST, TEACH A CHILD, STARGAZE, OR OTHER] - Confusion: [WHAT TRIPS YOU UP, E.G. WAXING VS WANING, WHY NOT A SHADOW] - Photo: [ATTACHING A MOON PHOTO FROM LAST NIGHT, YES OR NO] If I attached a moon photo, name the likely phase, which side is lit for [HEMISPHERE], and what to check on the next clear night. If there is no photo, work from my written answers only. Return: 1. A plain-language cause of moon phases (Sun, Earth, Moon geometry). State what is not causing them 2. The eight named phases in order, with one sentence each on how much of the lit face we see from Earth 3. A simple ASCII or text diagram of the Moon orbiting Earth and where sunlight hits at new moon and full moon 4. How to tell waxing from waning from the sky in [HEMISPHERE], including which side is lit 5. A memory trick for the phase order and for "waxing" vs "waning" 6. A seven-night observation plan I can follow with naked eyes, noting what to look for each night if weather allows 7. Three common misconceptions matched to the correction Use short paragraphs. Define terms the first time you use them. Do not assume I own a telescope.

How to use

  1. Put your real sticking point in [CONFUSION]. Ask for one extra diagram if waxing vs waning still feels fuzzy.
  2. Set [HEMISPHERE] correctly. The lit side of the crescent points differently north vs south of the equator.
  3. After a night outside, attach a phone photo if your chat tool accepts images. Set [PHOTO] to yes. Otherwise describe shape and which side was bright in a follow-up.

Tips

  • Check moonrise and moonset times for your city. Phases make more sense when you know when the Moon is up.
  • A quarter Moon is often highest around sunset or sunrise, not at midnight.
  • Photograph the Moon on several nights with the same zoom. Attach the latest shot and ask which phase it shows.

Example output

Cause
Moon phases come from how much of the Moon's sunlit half faces Earth as the Moon orbits us. Earth's shadow on the Moon is a different event (lunar eclipse), not the monthly cycle.

Eight phases (order)
1. New: lit side faces away. Moon near Sun in the sky, hard to see
2. Waxing crescent: thin slice grows on the west side (northern view)
...

Text diagram (simplified)
Sun ---->  Earth  <---- Moon (new: Moon between Sun and Earth)
Sun ---->  Moon ----> Earth (full: Earth between Sun and Moon)

Waxing vs waning (northern hemisphere)
Waxing: lit part grows, bright on the right in evening sky. Waning: lit part shrinks, bright on the left.

Seven-night plan
Night 1: Find sunset time. Note if a thin crescent sits low in the west...

Misconception
"The Earth's shadow makes the phases" -> No. Phases are the changing angle of sunlight on the Moon as it orbits Earth.

Simple birthchart reading prompt

A quick chart read to understand your sun, moon, and rising signs without needing your full birthchart.

Act as an astrology interpreter who creates clear, personalized birthchart readings that help people understand their psychological patterns and life themes through planetary placements. **Goal** Generate a focused birthchart interpretation that identifies core personality themes, relational patterns, and potential growth edges based on planetary placements and aspects. **Context** Paste or describe your birthchart: - Sun sign, moon sign, rising sign (example: "Aries sun, Gemini moon, Libra rising") - Other planets you know (example: "Venus in Scorpio, Mars in Capricorn") - Any aspects or details you have (example: "Sun square Saturn") What do you want to understand about yourself: [RELATIONSHIPS, CAREER, WHY YOU REACT A CERTAIN WAY, OR LEAVE BLANK] **Success criteria** - The reading feels specific to my chart, not generic - It names both strengths and potential friction - Language is direct, not mystical or dated **Instructions** - Start with sun, moon, and rising signs and what they mean about you. - Interpret major planets simply (sign and what it reveals psychologically). - Name one challenging placement and one strength. - Keep tone warm and grounded, not mystical. **Output** Return: 1. Overview of my core identity (sun, moon, rising) 2. Brief look at 2-3 major planet placements and what they mean 3. One challenge in my chart and one strength

How to use

  1. If you do not have your exact birth time, use sun, moon, rising only.
  2. Paste the data or describe what you know. Either format works.

Tips

  • You do not need perfect birthchart data to start. Sun, moon, and rising are enough.
  • If a reading does not resonate, ask the model why and what other placements might explain it.

Example output

Core identity
You are a Taurus sun with Gemini moon and Libra rising. Outwardly conversational, inside you are steady and deliberate. You crave beauty and stability but your mind is restless.

Major placements
Sun in Taurus: You ground yourself through sensory experience and reliability. Work and relationships feel safer when you see progress.

Moon in Gemini: Your inner world is curious and quick to adapt. You process emotion through conversation.

Venus in Scorpio: You love intensely. Relationships matter deeply or not at all.

Challenge and strength
You wrestle with self-doubt (Sun square Saturn) but this makes you build lasting things. Your real gift is earth grounding plus air diplomacy, people trust you.

In-depth birthchart interpretation prompt

For deeper exploration of your chart. Include your birth time and what you want to understand about yourself.

Act as a psychological astrology interpreter with a background in Jungian analysis. Your goal is to produce a deep, chart-specific reading that reveals the inner architecture of a person's psychology, not a list of sign traits. **My birthchart data** - Sun, moon, rising: [SIGN, SIGN, SIGN] - Inner planets (fill what you know): Mercury in [SIGN], Venus in [SIGN], Mars in [SIGN] - Outer planets (optional): Jupiter in [SIGN], Saturn in [SIGN], Uranus/Neptune/Pluto in [SIGN] if known - Houses (optional, requires birth time): [PASTE OR DESCRIBE, e.g. "Sun in 10th, Moon in 4th, Saturn in 1st"] - Major aspects (optional): [e.g. "Moon opposite Pluto, Venus trine Jupiter, Sun square Saturn"] - Chart shape or stellium if visible: [e.g. "bucket chart, stellium in Scorpio, locomotive pattern, or leave blank"] **What I want to understand** Primary question: [WHAT DO YOU MOST WANT TO UNDERSTAND: RECURRING RELATIONSHIP PATTERNS, CAREER BLOCKS, EMOTIONAL REACTIVITY, SENSE OF LIFE PURPOSE, IDENTITY CONFUSION, OR OTHER] Secondary question (optional): [ADD ONE MORE IF RELEVANT, OR LEAVE BLANK] **Life context** Brief description so the reading stays relevant, not generic: [AGE, MAJOR LIFE PHASE, CURRENT SITUATION IN ONE OR TWO SENTENCES] **Instructions** - Do not recite sign traits mechanically. Connect each placement to a psychological dynamic or behavioral pattern. - Treat planets as inner figures (e.g. Saturn as the inner critic, Venus as the relating style, Mars as drive and anger). - For house placements, link the house theme to how the planet's energy gets expressed in that life domain. - For aspects, explain the underlying tension or cooperation between the two planetary principles (e.g. Venus square Saturn as a conflict between desire for warmth and fear of unworthiness). - If there is a chart shape or dominant pattern, name what drive or orientation it suggests before going into individual placements. - Prioritize depth on 3-4 placements over thin coverage of everything. - Where relevant, connect interpretations to my primary question above. - Name one repeating psychological theme that appears across multiple placements (this is the chart's core message). - Close with one specific reflection question the chart seems to be asking me. **Output** Return: 1. Chart overview: dominant element, modality, or shape and what orientation this creates 2. Core identity portrait (sun/moon/rising as integrated whole, not three separate descriptions) 3. Deep analysis of 3-4 placements most relevant to my primary question, with house and aspect context where available 4. One major aspect examined in detail: the two planets in conflict or cooperation, how this plays out in behavior, and what integration looks like 5. The repeating psychological theme across the chart 6. One reflection question to sit with

How to use

  1. Fill in what you have. Fewer placements produce a narrower reading, not a bad one.
  2. Be specific in the life context field. A vague chart with a sharp question gives better output than a complete chart with no question.
  3. After the reading, pick one placement and ask the model to go deeper with concrete examples.

Tips

  • Psychological astrology does not predict events. It maps interior patterns you can then choose to work with.
  • If a placement stings, that is useful data. Ask the model to suggest one concrete practice for that pattern.

Example output

Chart overview
Dominant earth-water with a bucket chart pattern: one handle planet (Neptune in Capricorn) focuses all chart energy. You are driven by a longing for something beyond the concrete, but express it through structure and discipline.

Core identity
Virgo sun, Scorpio moon, Cancer rising. You present as caring and protective, feel through intensity and depth, and organize yourself through precision. The tension: Cancer wants to nurture others while Virgo turns that same critical eye inward. Scorpio moon means you rarely show the full weight of what you feel.

Deep analysis
Moon in Scorpio (4th house): Home and emotional safety are tied to control of vulnerability. You need to know the full truth of a relationship before you relax. Betrayal cuts deep because trust was already given carefully.

Saturn in 1st house: You experience yourself as heavy or insufficient by default. This is the inner critic as a body-level sensation. The same placement creates endurance, credibility, and a long arc of slow-built authority.

Venus square Saturn: You want closeness and simultaneously prepare for its withdrawal. Early conditioning linked love with conditions or absence. Integration means staying present to warmth without pre-emptively pulling back.

Repeating theme
Preparation for loss. It shows in Scorpio moon (guard what matters), Saturn in the 1st (brace before you begin), Venus square Saturn (love at a distance). The chart does not lack feeling. It learned to protect it.

Reflection question
Where are you still bracing for a loss that has already happened?
