Agenda: Here comes the sun March 21 1.Learning Target: I can explain my Science Fair project to other Astronomers 2.Kick-off: What was the most interesting thing you learned from someone else’s science project 3.Science Fair continued Fair participants. Most explain your project to each group that comes by. (three minutes) Fair observers-fill out sheet for each observation 4.SDO videos and Solar Week 5.Solar Storm DVD and Questions 5.Reading pages , concentrate on Discovery 16-1, write 10 questions 6.Iris Challenge-in class

A coronal mass ejection (CME) hit Earth’s magnetic field at 0600 UT on March 17, 2013, sparking a moderately strong geomagnetic storm (Kp=6) and auroras over Canada and as far south as Colorado. The impact lifted the solar wind speed from 300 km/s to 700 km/s. Read more at: ews/News cme.html ews/News cme.html Auroras are expected to continue over the next few days as the storm plays out. On March 19-20, more solar excitement can be expected as accelerated solar wind from a massive coronal hole reaches Earth.

Vocabulary CME (coronal mass ejection) Solar cycle aurora

Sun weekly challenge in class ov/iris_weeklyquestions.htmlhttp://irischallenge.arc.nasa.g ov/iris_weeklyquestions.html Question #6 is online ready for you to research and respond. The compound question is: What is a sun quake? What is a Hyder flare? Your answer should be submitted to: m/s/6TZGL5Q m/s/6TZGL5Q

Quiz 1.What is the SDO? 2.What are the three instruments on the SDO? 3.What is a solar storm? 4.What causes auroras? 5.What impacts can solar storms have on Earth?
