Below is my assignment for the astronomy lab I am taking. I would
LAB 1 - ObservationUnlike the labs in the text (which will each take a week to complete), this lab willtake several weeks to complete.Please see the bulletin board or course calendar for the specific date this lab is due.This lab involves naked eye observations of the darkness of your sky, the Moon(both its position and phases), the rising or setting positions of the Sun, and theplanets.Please print the observation sheet (the last page of this lab). You will be drawing onthis sheet to complete this lab exercise. PART 1: The Darkness of Your Night SkyOn a clear night, once your sky is dark, please set your sky clock to the currentdate and time. Using your sky clock as a guide, look towards the north and findboth the big and little dippers in your sky (note the little dipper stars are not asbright as those in the big dipper).Once you locate the little dipper, find the dimmest star of the group that you cansee (naked eye). This will be an indication of the limiting magnitude of your sky.Note that a normal eye can see stars down to 6th magnitude under truly a dark sky.If you live in a major city, the limiting magnitude might very well be much higher(3 or even 2). Please write down the limiting magnitude of your viewing locationon the provided observation sheet. Use the image below as a guide for determiningthis value (note the dippers may be rotated from this view depending on thedate/time of your observation): If your value is 3 or 2, you should feel quite disgusted about the level of lighting inyour area. For more information about the problem of artificial lighting ruining ourability to enjoy the night sky, please visit the International Dark Sky Society'swebsite:http://www.darksky.org/ PART 2: Moon and Sun ObservationsOn the blank observation sheet provided, draw (as best as you can) your horizon(from the east to the south and around to the west). You can determine yourdirections by use of a compass or by the star Polaris (in the north). Use the skyangles sheet to approximate the appropriate height of hills along your horizon. Thisimage will serve as the basis for all of the following observations you willcomplete, so do your best!A. The MoonI have posted the dates of the nearest new and full moons (please check the bulletinboard and/or calendar).Starting a couple of days after the new moon, please go outside, around sunset, atthe same time (every two days or so) for two weeks. Draw the position and phaseof the Moon on your horizon chart. Use the sky angles guide for approximating theposition of the Moon in your sky. Next to each moon image, please write in thedate and time of your observation.If you are not able to perform these observations at sunset, you will need toperform them at sunrise. In this instance, begin your observations starting a coupleof days after the full moon. Observe the position and phase of the moon at thesame time (every one or two days) for two weeks. Draw the position and phase of the Moon on your observation sheet. Use the sky angles guide for approximatingthe position of the Moon in your sky. Next to each moon image, please write in thedate and time of your observation.B. The SunNEVER LOOK DIRECTLY AT THE SUN (EVEN FOR A MOMENT)!! PERMANENT EYE DAMAGE WILL RESULT.On the same observation sheet used above, please draw the setting position of theSun in the west once every 5 days or so. Label the date and time of yourobservation next to each setting position on your chart.If you are not able to perform these observations at sunset, you will need toperform them at sunrise. In this instance, begin your observations around the dateof the full moon, and draw the position of the rising Sun in the east once every 5days or so. Label the date and time of your observation next to each rising positionon your chart. PART 3: The PlanetsOn a clear night, set your planisphere to the current date and time. Look in the skyand see if there are any bright stars in the sky not present on your planisphere. Ifthere are, these are planets! For all you find, plot their position on your observationsheet. After doing so, please determine what planet each is by looking at yourmonthly skymaps, and label them on your observation sheet.
