The planet on which he was living underwent each day two mornings. First CY30 appeared and then its minor twin put in a feeble appearance, as if God had not been able to make up His mind as to which sun He preferred and had finally settled on both. The domers liked to compare it to sequential settings of an old-fashioned multifilament incandescent bulb. CY30 gave the impression of getting up to about 150 watts and then came little CY30B, which added 50 more watts of light. The aggregate luminae made the methane crystals of the planet's surface sparkle pleasantly, assuming you were indoors.
