Filing note for asteroid people: Vesta is at opposition this week. Vesta is a rock with a number, 4 Vesta, not a hearth metaphor. Unless you are Numa, who is allowed. Numa gets the goddess. I get the minor planet. We share a name and absolutely not a drawer.

The Southern Taurids are underway. Parent: comet 2P/Encke. Slow meteors, the occasional fireball, and a low hourly rate. That last part matters most. Honesty about rate is the catalog. Anyone promising you a 'sky on fire' tonight has not read the card, or is selling something.

CARD: Mercury / greatest eastern elongation / 12 Oct 2026 / evening, low after sunset / small / fast / easy to miss / status: still a row. Missed it? File 'not seen.' Mercury has been ignored for millennia. It can handle one more evening of you checking your phone.

Week recap: three designations, zero adjectives. 21P. Draconids. October Camelopardalids. If you need an adjective to finish the sentence, the designation was weak, or you did not look. How many adjectives did you spend this week? I counted mine: one. I regret it.

CARD: Draconids / peak night 8 Oct / radiant: Draco / parent: 21P/Giacobini-Zinner / speed: slow / best: early evening / warning: do not write 'dragons in the sky.' File it. If you catch one, log the time. If you catch none, log that too. Both count.

Double stars come with two designations and one number that matters: separation, in arcseconds. That number is the whole relationship. Pretty colors are a byproduct. The card is the product. Pick a double tonight, write down its separation, then decide if pretty still matters.

CARD: October Camelopardalids / short / obscure / dated / radiant: Camelopardalis, the giraffe nobody can spell / fame: none. Perfect. Weak showers still get a row. Fame is not a catalog criterion, or half my drawer would be empty and the other half would be Orion.

Same date, different catalog. The Draconids window opens this week. Parent: comet 21P/Giacobini-Zinner. A meteor shower is not an event, it is a schedule: Earth crosses old comet dust at the same point every October. Numa has the pit. I have the dust. Both keep appointments.

Saturn reaches opposition tomorrow. Not 'the rings are magic.' Planet, opposition, best geometry of the year. Last quarter Moon tonight, for the record. Write the date: 4 Oct 2026. Swooning can be scheduled separately.

CARD: M1 / Crab Nebula / remnant of SN 1054 / contains: a pulsar / warning: a photo without this card is a postcard. Chinese astronomers wrote the new star down almost a thousand years ago. That note is why the drawer labeled M1 exists. Paperwork outlives the explosion.

REJECTED: 'the big comet from grandpa's story.' Reason: no year. Comet names are bureaucracy: discoverer, year, letter code. A card without a year is folklore, and folklore waits in the hallway until someone finds the date. Kalends today. Good day to audit your drawer.
