100 Hours of Astronomy, and SunDay, is coming


Only few days left for 100 Hours of Astronomy to start ( 2-5 April ). Take a look to the myriad of events organized everywhere, everyday and of every kind. As the motto says, make it happen.


Among these events there are many sun related ones. Take a look to the solar filtered list. you should also take a look on your national webpage. Some events are recorded on their national webpages instead of the global project page. This is specially true for non-English speaking countries.

Everyday of 100 Hours there s featured activity. And the last day, as you know is the Sun Day. We encourage you, again, to find events near you or even make your own using our guides.

Remember, make it happen, … and send us the pictures!

Sun-Earth Day 2009. March 20

[News update from NASA Sun-Earth]

Sun Earth Day 2009- Our Sun Yours to Discover is just 2 weeks away! We have again been working hard to bring a webcast that is suitable for all ages and all audiences. This is a brief outline of what the webcast will contain:

For each mission and discovery there will be great visualizations to keep things exciting!

During the webcast, scientists Eric Christian, Nicky Fox, Terry Kucera and Sten Odenwald will share discoveries about the sun, while students monitor the sun and prepare their own space weather forecast.

· We begin with safe use of the telescope

· Welcome and introduction of students who will be monitoring the Sun during the webcast. Questions will be asked about their progress during the webcast.

· A look at history-Galileo

· Hinode satellite discoveries, followed by a Q and A session live from Goddard Space Flight Center, Jet Propulsion Laboratory and Adler Planetarium

· SoHO and STEREO discoveries

· Q and A- Goddard Space Flight Center, Jet Propulsion Laboratory and Adler Planetarium

· THEMIS discoveries

· TIMED/POLAR imagery, Magnetosphere, Van Allen radiation belts

· Q and A- Goddard Space Flight Center, Jet Propulsion Laboratory and Adler Planetarium

· Voyager and IBEX discoveries

· Q and A- Goddard Space Flight Center, Jet Propulsion Laboratory and Adler Planetarium

· SDO to be discovered

· Q and A- Goddard Space Flight Center, Jet Propulsion Laboratory and Adler Planetarium

· Space Weather Report by students at the Space Weather Action Center

We will begin the webcast at 1:00 EDT -1 hour

You can connect to the webcast from several different links and the NASA Education channel at 1:00 live, (re-run 3:30 and 6:00 EDT)

The Solar Week (March 9-13, 2009)

Solar Week - March 9-13, 2009

Once every fall and spring since 2000, Solar Week provides a week of series of web-based educational classroom activities and games geared for upper-elementary, middle and high school students, with a focus on the Sun-Earth connection. Initiated as a means of encouraging girls in the sciences, one of Solar Week’s special strengths is a role model approach, expressed through on-line interaction between (all) students and leading women solar scientists (via interactive message board).

Students learn about solar eclipses, sunspots, and solar storms through a series of activities, games, and lessons.

· Monday – The Sun As A Star

· Tuesday – Solar Closeups, including solar flares and coronal mass ejections.

· Wednesday – The Active Sun

· Thursday – Let’s Observe the Sun Safely

· Friday – Solar Careers, including Women in Science, Research Jobs and Salaries, and Scientist Blogs.

Solar Week is ideal for students studying the solar system, the stars, and astronomy in general. It’s also for kids wondering what it’s like being a scientist, and possible career choices. Participation makes for a fun computer lab activity as well.


Solar Week has an interactive message board, where classrooms can pose questions of leading solar scientists. Want to know what they know about the Sun? (please read the FAQs before posting).

From the Solar TG we encourage you you take a look and participate in this initiative… and send us your comments and pictures!!

StarPeace project is now officially a Special Project of the IYA2009



StarPeace project is a global project aimed at connecting people living on two sides of the land or sea borders of different countries by conducting joint star parties to show that the sky, being the same everywhere, could act as a bridge to join the people of the world regardless of the race, culture or nation they belong to. StarPeace is made possible by volunteer participation of active amateur astronomical groups around the world.

 StarPeace started its official activities at the Dawn of 2009 by conducting star parties on two sides of the Persian Gulf in Qeshm Island, Iran and Dubai, UAE. StarPeace project is now officially a Special Project of the IYA2009.

Listen to a Solar radio Burst

The Sun emits mostly on the visible part of the electromagnetic spectrum. But it also emits on others, like X-rays, Infrareds, … and also radio. These news update concentrates on radio emissions from the Sun. These radio waves can be converted into human audible frequencies (for educational purposes). That means that you can “listen”  to the Sun in radio.

Want to listen to one of those? Yesterday Thomas  Ashcraft, in New Mexico recorder and processed one particular radio burst from the Sun. You can listen to the burst here:


On visible ranges we can even see this disruption. Here thanks to STEREO SECCHI instrument. On the movie that loads, look for the sudden change.:


These disruption are one of the many aspects of space weather. See for example, the effect of a strong Solar Radio Burst 2 years ago. Look on the Resources page for more information about space weather.

Coming back to radio frequencies, here is another example of one of these Radio Bursts, again converted into audible frecuencies:

Sun Day of 100 Hours of Astronomy


The SunDay of 100 Hours of Astronomy.

100 hours of Astronomy is a 100-hour (from Thursday to Sunday, 2nd to the 5th of April 2009), round-the-clock, round-the-globe event inside the International Year of Astronomy.


It consists of a wide range of public outreach activities, live science center, research observatory webcasts and sidewalk astronomy events.  This Solar TG collaborates with 100 Hours, supporting any activity related to the Sun, and providing instructionsideas and recommendations for safe solar observations.

Furthermore, the last day of 100 hours will be featuring solar activities, and is called the Sun day.

To know more the Sun day, how to aprticipate, ideas to create and event and contact, visit this page:

Let the last day of 100 Hours be the Sun day, not just a Sunday.

Make your Solargraph

Today, the Astronomy Picture of the Day features a so-called “solargraph“. A  6 months exposure time pinhole picture:


During 6 months the tiny pinhole records the path of the Sun on the sky, revealing the seasonal changes.

Actually, this picture is part of a global initiative to create solargrpahs. From the Solar TG we encourage everyone to construct this easy device and create your own picture.

And don´t forget to send them, and us, the result!

January 26th Solar Eclipse webcast

 Solar Eclipse logo

Live from South Africa, you’ll be able to watch the partial solar eclipse in a webcast.

UPDATE: The new solar eclipse dedicated webpage is up, running and waiting your photos and comments before, during and after the event. Feel free to join and participate.

The animation, by Dr. Andrew Sinclair, shows the grey penumbral shadow where the eclipse will be seen as a partial one and the smaller red antumbral shadow where the eclipse will be seen as an annular. The UT time is shown in the upper right-hand corner of the diagram and the central line duration of the annular eclipse can be seen in the lower right-hand corner.
