In the Nautical Almanac provided, when would Jupiter and Saturn be visible in temperate latitudes for both evening and morning stars?
• Nautical Almanac daily pages — how planetary visibility (rising/setting) is shown for different latitudes • Difference between morning star (visible before sunrise in the east) and evening star (visible after sunset in the west) • How temperate latitudes tables differ from equatorial or polar visibility
• Look at the Almanac pages around each of the four dates and see on which dates both Jupiter and Saturn have times listed that place them in the sky during evening and again before dawn • Think about how the planets’ positions relative to the Sun affect whether they can be seen both after sunset and before sunrise on the same date • Compare which dates show Jupiter and Saturn above the horizon during civil twilight in both the evening and the following morning for temperate latitudes
• Confirm on the Almanac page for each choice date that both Jupiter and Saturn have visibility entries for temperate latitudes • Verify which date(s) show them clear of the Sun’s glare long enough after sunset and before sunrise to be classed as evening and morning stars • Make sure you are reading the right latitude band in the visibility table (temperate, not equatorial or polar) before deciding
