Altair: Decan 19 - Vision & Speed (September 16-25)

The photons entering your eyes right now left Altair in 2008. This A7 V white main-sequence star rotates once every 8.9 hours, so fast it has squashed itself into an oblate spheroid. In 2007, it became the first star other than the Sun whose surface was directly imaged. The Flying Eagle opens Decan 19 with vision and speed: see clearly, move fast, accept the shape that velocity gives you.

Regulus: Decan 11 - Sovereignty & Heart (June 28-July 7)

The photons entering your eyes right now left Regulus in 1946. The Heart of the Lion spins at 96.5% of its breakup velocity, holding itself together at the edge of self-destruction for a quarter of a billion years. Every civilization that observed this star independently called it king. June 28-July 7: claim your sovereignty and discover what it costs to hold it.
