morning sky. This narrow angle keeps the thin waning crescent moon and the star Regulus buried in the glare of dawn at southerly latitudes.
• Sun at zenith over Earth's equator on September 22 equinox
• For example, at Boston, Massachusetts - at 420 north latitude - the moon rises about 100 minutes before the sun and Regulus rises approximately 110 minutes before sunrise. But directly south of Boston - at 42o south latitude in South America - the moon comes up about 70 minutes before the sun whereas Regulus rises about 50 minutes before.
• By the way, mid-northern latitudes in Europe - and especially Asia - may even see an old and extremely-thin waning crescent moon before sunrise on Saturday, September 15.
• Bottom line: There has been some excitement all week in the predawn sky as the moon passed first Jupiter and then Venus. Now the moon is an old moon, a thin waning crescent near the sunrise. See if you can spot the lunar crescent and Regulus over the eastern horizon before sunrise on Friday, September 14. Next week, the moon will return to the western sky after sunset.
