Module 6

State the B-v, the absolute and apparent magnitudes and the distance in parsecs and light years for each of your 3 stars.

Module 5

Give the 3 names of your stars. For each star state the temperature, the class, the balmer lines and any other absorption lines that you used to determine your classification. Then go to the simbad website and find the B and V magnitudes for each  star.

Module 1, Assignment 2

What is the largest value you can find within the image of the sun? Let’s call these “Data Numbers” or DN value.Comment on what you estimate is your measurement accuracy. How many significant figures are meaningful? (In other words, can you measure the diameter to an accuracy of one pixel? One tenth of a pixel? One hundredth of a pixel? None of these?)How much fainter in DN units is the sunspot than its surroundings?Repeat your measurement of the Sun’s diameter several times and post your average value of the diameter in kilometers on the Blog. Include a comment about sig figs.
Describe the general nature of the sun's surface around the location of this sunspot.
