Article: Sun Experiences Seasonal Changes, New Research Finds.
"Sun Experiences Seasonal Changes, New Research Finds." ScienceDaily. ScienceDaily, n.d. Web. 07 Apr. 2015.
Recently, a new study by a team of researchers and astrologers, led by the National Center of Atmospheric research (NCAR), found that the sun experiences changes and withstands a seasonal changeability where its activity is waxing and waning over the course of about two years. The suns inconsistent behavior affects the peaks and valleys in the eleven-year solar cycle and sometimes weakening the solar storms that can strike the Earth's atmosphere. Scott Mcintosh, the lead author of the new study and director of NACR’s High Altitude Observatory said that in the below picture “What we’re looking at here is a massive driver solar storms” and by better understanding the activity of the solar storms and how these activity bands form in the sun and cause seasonal instabilities, the potential to vastly improve forecasts of space weather events.
According to the observations by the research team at NACR, the overlapping magnetic bands are powered by the rotation of the Suns deep interior. This causes the bands to move within the Sun’s northern and southern hemispheres, activity rises to a peak as the bands move over a period of about 11 months, which is also part of a longer cycle that lasts about 22 years, and then begin to wane. This is called a quasi-annual variation, and can be compared to regions on the earth that have two seasons, a dry season and a rainy season. 
The new study led by the National Center of Atmospheric Research is only one of a variety of research papers by the NACR research team that examines the magnetic bands on several; interrelated cycles of solar magnetism. In a paper last year in the Astrophysical Journal, the authors grouped the 11 year sunspot cycle in terms of the two overlapping parallel bands of opposite magnetic polarity that slowly migrate over almost 22 years from high solar altitudes towards the equator where they discontinue. Researchers can now look to modern computer simulations and receive more detailed observations to find new discoveries in the the profound influence of the bands on solar activity.
I like how you used evidence, such as the experiments put forth, to back up your topic and convince the reader. The way you confronted your topic made the audience aware of the Sun`s changes. I also like the image you chose to support your essay, it is relevant to your topic and looks interesting.

Lauren, I I thought that you did a very nice job on your current event. I like how you include a picture in your review. It helps the reader gain a picture of what you are talking about. Likewise, I like how you made your summary very thorough. By making your summary very thorough the reader can clearly understand what the article was about and make connections to their own life. Moreover, I like how you use excerpts from the article and quotations from the experts. By using these excerpts, you show that your article has expert analysis from real scientists proving the author as well as the article have scientific credibility. Your facts are backed up by your quotes and it makes your review and article more scientific.
I found it interesting that the sun, a star, has seasons. I wonder if other stars have seasons as well. I also found it interesting that scientists could even figure out that there are seasons on the sun. Finally, in order to improve your article review. I suggest that you make your critique and relevance paragraphs more distinct. I feel like you barely touch on these two parts of the review and in order for a reader to gain an idea of whether this article is credible, you must critique it and state its flaws.

ReplyDeleteI liked the Introduction, picture, and theme. I really like how the paper is formatted correctly through the entire paper. After reading the hook you know what your going to be reading. The picture helps me get and idea of the suns solar storms. The theme of the paper is very interesting, the suns seasonal changes is a new idea and i'm glad there was a current event on it. One thing that I would fix is the placement of the picture, its messed up the format of the current event.

ReplyDeleteLaurens review of her current event article was very clear and straight to the point about what her article was about. She gave us a very informative summary of the information in the article but kept it short which made it a nice and easy read but yet informative at the same time. I like how Lauren gave us names and specific information taken straight from the article, and then explained the quotes taken from the article. This really gave us a better understanding of what the article was talking about, and showed us what the professionals of this topic have to say about it. Lauren did a great job of not only telling us the information in her own article that she picked, but telling us that there are plenty of articles on this too. It is great that Lauren informed us of some of the articles, because if someone had read her article and liked this topic, they could then explore more and learn more about it by going to the other articles that Lauren suggested. Lastly, I like how Lauren kept referring back to the Article and the information in it. For example, when Lauren had said in her review “According to the observations by the research team at NACR…” It lets us know that she is looking at the information shown in the article, and then making her own connection with it by putting it in the article.
ReplyDeleteI learnt many new things reading Laurens article because I do not know a lot about this topic, but one very interesting thing that I read in Laurens article was about the suns behavior. I did not know that the sun has inconsistent behavior, and that this inconsistent behavior can have an affect on the peaks and valleys in the eleven-year solar cycle. And that the weakening of these solar storms can strike Earth and impact us. So by not only learning about the suns inconsistent behavior, Lauren also taught us about future damage that could be caused to Earth by the suns behavior. Reading Laurens article I also learnt that the Sun experiences a quasi-annual variation, which can be compared to regions on Earth that have two seasons, and dry season, and a rainy season.
Laurens review was very well written, and very informative, but I would make a suggestion that she tells us more about the change the suns seasons, because I would have liked to hear more information about it.
I decided to comment on Lauren’s current event response to an article about the Sun’s seasonal changes, and I think that Lauren did a good job, and I liked many aspects of her response. For example, I liked how Lauren’s grammar was very good, and she did not have any punctuation or spelling mistakes that I could discern either. This made Lauren’s review easy to read and understand, and this is always good when reading something. I also liked how Lauren compared the seasons of activity in the Sun to something that ordinary people can understand (dry and rainy seasons on Earth). In doing this, she simplified a relatively complex idea for the average person, and made the information that she was presenting much more easy to understand. I know that for me, at least, this comparison made understanding Lauren’s topic much easier. Finally, I liked how Lauren included an image in her response, as this caught my eye and made me want to read her article immediately. Also, the image was related to her topic, and because many people are visual learners, the image will help people reading her response to understand her topic.
ReplyDeleteI did not just like Lauren’s review for the way in which it was written, but also because of the information she included because it taught me a lot. For example, I learned that the Sun has seasons, similar to rainy and dry seasons on Earth, where its activity falls and rises over time. This was very interesting because I did not think that stars could have seasons like a planet. Also, I learned about how the rise and fall of solar activity can affect solar storms which can actually affect people on Earth. Therefore, not only did I learn something completely new, but I learned about how it can actually change my life and those of people around me. This shows that the quality of information in Lauren’s review was very good.
Even though I liked all of these things about Lauren’s response, I thought that she could have done something better. I think that Lauren should have included a critique about the article that she read, because I did not see this in her review. However, aside from this, I thought Lauren did a very good job.
