Message from CFHT Librarian, Liz Bryson:

Aloha! Welcome to our latest version of Hoku! Thanks to our summer students, Tito Jankowski & Jeff Mori, for the new look to our web site.

We are grateful for your feedback and support of our venture. Feel free to send us an email.

CFHT Community Outreach

July 3, 2005: Deep Impact, we were participating via video conf (Gary Fujihara at IfA in charge), and prepared images and near realtime movies for the public shows.

Deep Impact


August 28, 2005: The Waimea Festival was very successful. We had a booth with the telescope model, making a comet, and stickers. Many visitors and a lot of interest, small posters very popular.


August 28, 2005: CFHT Star Party on the front lawn of the CFHT offices in Waimea. Unfortunately the clouds only parted for about 40 minutes for observing through the telescopes. There were many groups passing through the Remote Observing Room at the downtown office.


Upcoming Events

Early October: There is a Japanese Film Crew visiting the telescope for an afternoon of filming.

December 3rd, 2005: Star Party after the Christmas Parade of Lights in Waimea will be open to the public.

Various Tours of the summit coming up for teachers and students.

Explore the Sun

The sun is extremely HOT. Core temperature can reach 22.5 million degrees!

But what does it all mean ? How do scientists know these temperatures?

Continue into this journey and let's find out!

Fun In the Sun: Introduction to the Sun Activities

Maintained by the High Energy Astrophysics Division of the Harvard-Smithsonian Center for Astrophysics, the Fun in the Sun: Introduction to the Sun Activities Web site offers some interesting learning activities. Students get to learn how to measure the size of the sun, how to determine the amount of energy that comes from it, and how angles spread sunlight. Each activity requires some basic materials such as paper and a yardstick, as well as a trip outside on a sunny day. Unfortunately, the activity instructions page is not very well organized, but does give all the necessary information for completing the tasks. These fun lessons are a great way for kids to spend a spring day learning about science.

StarChild: The Sun

This site provides information about the sun. You can choose two levels of pages based on the age of the students that use it.

StarChild: The Sun Site


The Schoolyard Solar System

"The Schoolyard Solar System was developed to demonstrate the solar system to scale; to show the relationship between units of thousands, millions, and billions; and to accomplish these goals with student involvement that will re-enforce the lessons." Students and educators can find images of the Sun and the nine planets in our solar system. The website presents bulk, orbital, and observational parameters as well as additional facts for the objects. By printing out the materials and following the hands-on activity discussed at the website, students can learn about the scale of the solar system.

Sun Fun


Here is a great NASA site which has everything one might think of including sun facts, sundials and telling time, how our weather depends on the sun, mythology, observing, and the parts of the sun.

Stanford Solar Center

The Stanford Solar Center is a project of the Solar Oscillations Investigation Team at Stanford and "is dedicated to sharing the joy and excitement of solar science exploration by providing hands-on web-based activities." Several quality educational lesson plans are provided on the site with titles such as Effects of the Sun on Our Planet, Build a Spectroscope, What is Ultraviolet Light?, The Spinning Sun, Galileo Challenge, Magnetism and the Sun, Sun Centered Physics, and more. Each contain a summary of the activity, its objectives, suggested grade level, and downloadable resources, all culminating in a easy-to-use resource that would be a welcome addition to any science curriculum.

Upcoming Astronomical Events
  1. Eclipse - There is a partial lunar eclipse on October 17th. It will be completely visible from Hawaii. The event will start at 11:51pm on October 16th, and will continue until about 4:15am on October 17th. Greatest eclipse will be at 2:03am. The moon will be passing through the penumbral shadow of the earth, not the darker umbral shadow so it will not be too red in color. There should be a noticable darkening of the moon.
  2. Meteor Showers - Don't forget to watch the Orionid meteor shower on the evening of October 20th, and morning of the 21st. Best viewing time is midnight to sunrise with the peak occuring at 11pm on the 20th. Predictions are 20 meteors per hour. The moon will be just past full so it will be bright, hampering good viewing of the shower. It is best to bring along a sky chart to identify the constellations in this case Orion and then look in that direction. The Leonid meteor shower will be at its peak in the early morning of November 17th. The predictions are around 15 meteors per hour for this event. The moon will be bright but should set before twilight, so viewing will be better after it sets. The best show will be the Geminid meteor shower which will be at its best on the evening of December 13, and morning of December 14th. Peak is about 8pm on the evening of the 13th but even with the bright moon, 120 meteors per hour have been predicted. See the August 2001 issue of Hoku in the archive to learn more about watching meteor showers.
  3. Planets - Mars will be at its closest to earth in the evening of October 29th. Shortly after its greatest elongation East on November 3rd (best view from the southern hemisphere), Mercury will be 1.3 degrees N of the moon. Venus also reaches its greatest elongation on November 3rd. Venus will be at its most extreme declination (-27deg 05min) 3 nights later on November 6th. Mercury will be better for the northern hemisphere when it reaches its greatest elongation W on December 12, best viewed right before sunrise either on the 12th or 13th.
  4. Solstice - The winter solstice will be occuring on December 21st at 8:35am.
  5. Daylight Savings Time Ends - In the early morning of Sunday October 30th, people on the mainland will be getting an extra hour of sleep as daylight savings time ends.

All times listed above are HST. The link below contains many calendars and includes a nice section on astronomical events. Check it out!
