Final answer:
The time of sunset varies depending on geography and date. In the Northern hemisphere, in October, the Sun transitions from spending more daylight hours, thus causing an earlier sunset. An exact time would require the specific location.
Step-by-step explanation:
The time of sunset varies depending on geographical location and date. The question of when sunset occurs specifically on October 23, 2010 is challenging to address without this information. As shown by Figure 4.7 The Sun's Path in the Sky for Different Seasons, the Sun follows a different path across the sky at different times of the year.
In the Northern Hemisphere, the Sun sets north of west around June 21 when the Sun is above the horizon for about 15 hours. Around December 21, the Sun sets south of west as it remains above the horizon for only about 9 hours. However, on or around March 21 and September 21, the Sun spends equal amounts of time above and below the horizon.
In October, the Sun starts transitioning from spending more time above the horizon to less in preparation for the winter solstice in December. Therefore, on October 23, 2010, the duration of daylight would have been shorter than in the summer months and the Sun would have set earlier. However, an exact time for sunset would require the specific geographical location.
