Sun Observation

In this observation, you will be observing the sun and learning about the current space weather forecast. Since we cannot directly observe the sun without blinding our eyes, we will be looking at the sun from the comfortable seats on your house, or on a laptop which could even be connected in your carport while you are winter camping someplace. Your assignment is to complete this worksheet by surfing the web on recommended websites for answers to my questions.

Now, click on box that says "The Sun Now" and look closely at the MDI Continuum photo of the sun as it appears today, and count the number of visible sunspots on the sun’s disk. How many spots do you count in the image?


#4 Please look at this next website to answer a few questions. The site is http://www.spaceweather.com. The questions are
What is the "space weather forecast" for today?
I. solar wind speed:
II. How far south did the Auroral Loop extend when you were logging onto the site?:
III. solar flare possibility (X and M class):
IV. geomagnetic storm forecast: (mid-latitudes):
V. As you look at this site, is there anything of interest happening today or tonight that might be exciting for astronomers to see, and if so, what might that be?


#5 Finally, go to a relatively new website TRACE and answer one question ... what is "TRACE" and what does it study? After you answer this question, go to Trace Picture of the Day, and spend some time gazing at this"image." Finally, you have got to check out the archives of TRACE satellite pictures. It takes a little time to upload all of the pictures, but when you scroll down and click on some of the images, they might be the most amazing pictures in this entire course. In a few words, describe what you thought of some of these pictures.

What is "TRACE?"

In the space below is the room for your comments about the Trace Archive of Pictures


When you have answered the questions, please press the submit button. Have a nice time viewing the sun :) You should also check the mirror to see if you got too much sun today from this observation, and whether you need some Aloe to reduce the burn.
