Up: The Sky Previous: Sidereal Time

Southern Hemisphere

Our observatory at Mt. Kent is near Toowoomba, Australia, about 100 km from Brisbane. Mt. Kent is located at -27 deg 47 min 52 sec and -151 deg 51 min 19 sec.

15. Convert both to decimal degrees, and convert the longitude to hours, minutes and seconds of time.

16. Identify a bright star in the northern sky that is not visible from Mt. Kent and give its celestial coordinates.

17. What is the difference in standard time and date between Louisville and Toowoomba? For example, if it is 6 PM Monday here, what day is it and what time is it in Toowoomba?

18. If Sirius is crossing the meridian here at 9 PM, at what local time would it cross the meridian in Toowoomba?

19. Does the Sun rise in the East and set in the West as seen from the southern hemisphere?

20. If you face south at mid-day at Mt. Kent in July (winter in the southern hemisphere), the Sun passing across the meridian, is it moving from left to right or from right to left?
