(Remember to take Daylight Savings into account. The starting and ending dates vary, but to simplify the questions, assume Daylight Savings is in effect from March 1 through October 31.) In which direction should the star wheel be rotated in order to simulate the actual motion of the night sky: clockwise or counterclockwise? Explain how you can tell by examining your planisphere. 1. 2. According to the phanisphere, what bright star is directly overheadi 3. What constellation is visible on the southern horizon? 4.

Explanation / Answer

As per norms I should answer for first question only

1) Clock wise

On Sunday, March 11, most Americans will set their clocks forward an hour, as daylight saving time (sometimes erroneously called daylight savings time) begins and most of the United States can bask in an extra hour of daylight. These spring and fall clock changes continue a long tradition started by Benjamin Franklin to conserve energy.

Historically, daylight saving time has begun in the summer months and ended for winter, though the dates have changed over time as the U.S. government has passed new statutes, according to the U.S. Naval Observatory (USNO).

Starting in 2007, DST begins in the United States on the second Sunday in March, when people move their clocks forward an hour at 2 a.m. local standard time (so at 2 a.m. on that day, the clocks will then read 3 a.m. local daylight time). Daylight saving time ends on the first Sunday in November, when clocks are moved back an hour at 2 a.m. local daylight time (so they will then read 1 a.m. local standard time).

Last year, DST began on March 12 and ended on Nov. 5. And this year, DST begins on March 11 and ends on Nov. 4, 2018. You will then move your clock forward an hour on March 11, 2018, and the cycle will begin again.
