I took this after the eclipse, but the sun is fascinating at any time. I never gave thought to how complex its systems are, but I will think about how remarkable it is every day for the rest of my life. At least, on the sunny days.

This is one of the best courses of the many courses I have taken on Coursera.

Dr Duncan is excellent. Down to earth (so to speak) descriptions of quantum phenomena that explain common, everyday solar event. Graphics are terrific. The material is arranged in straight forward manner with excellent instruction by Dr Duncan.

Cannot think of a better way to learn this subject matter.

Thank You!

I enjoyed this course so much, and watched the eclipse the best I could that day.

Good Knowledgeable course for all the students. This course has increased my knowledge about the solar system and earth.

Awesome!

It was short, sweet, very timely matched with solar eclipse.

Great preparation course. Totally enjoyable.

The peer review process was confusing when there were no submissions to review. Would like to have more communication about what to do in this instance.

Excellent Course

Excellent information for a brief overview of the eclipse and the science behind it!

Interesting course.

Dr. Duncan's course was stellar. It gave a comprehensive overview about the science behind a solar eclipse and the inner and outer workings of the Sun. I was able to use the knowledge gained to hold a presentation about solar eclipses at the local school in Spray, Oregon, in the path of totality and it was very well received.

Great course, came just in time. Nice tutorial for this wonderful event! I like it!

This course shows how beautifull a Total Eclipse of the Sun is. Douglas Duncan is so enthusiastic to tell about the Sun. He shows you different lessons with beautifull websites that you probably didn't see earlier. It is not a difficult course, so anyone can follow this course. After this course you probably will be interested in more courses on Astrophysics, Astrobiology, Planetary, and Earth Sciences.

Awesome experience. Great information. Highly recommended. :)

Extremely informative. Course not only explained the Aug. 2017 eclipse, including extensive safety tips and viewing options, but also went into detail about solar studies. The offering of this course was very well-timed. ;)

This course is amazing and that's not all! Its quality is super and the lecturer is clear and understandable!

Thank you for the time you spent providing people with free education it's so valuable and i appreciate it!

Infinitamente agradecido con el docente, mis compañeros y por sobretodo la comunidad de Coursera, por brindarme la oportunidad de formarme como profesional y contribuir a superarme, apoyándome incluso con la situación económica que atraviesa mi país, realmente les deseo lo mejor y me comprometo a traer personas a que aprendan con esta plataforma única en la red.

Very nice and insightful

I learned a lot and wished I'd known how interested I am in physics. Looking forward to August 21, 2017. Thanks Dr. Doug for your teaching!

Excellent Course structure. This course is suitable for all the college going students and for all branches. Thus a universal course.

I really enjoyed doing the assignment on determination of sun spots. I will be repeating that experiment multiple times (and also using my own data once the monsoon season is over) to improve my analytical and observational skills. Thanks a lot for this course.

great and timely course!

The Course was great, except for two things. one it was too short :-), and two, the peer graded projects were confusing.
