A partial solar eclipse isn’t nearly as spectacular as a total solar eclipse when the Sun is completely covered for a few minutes. Nevertheless, it’s still an amazing sight to behold – ... sight is the thing to beware of as any attempt to look at the Sun with binoculars or a telescope (or even the naked eye) can result in blindness. The Gisborne Astronomical Society is opening the Cook Observatory on Kaiti Hill from 4:45pm this Thursday to show people how to view the event safely.

The Sun–Earth connection is studied using long-term measurements from the Sun and from the Earth. The auroral activity is shown to correlate to high accuracy with the smoothed sunspot numbers. Similarly, both geomagnetic activity and global surface temperature anomaly can be linked to cyclic changes in the solar activity. The interlinked variations in the solar magnetic activity and in the solar irradiance cause effects that can be observed both in the Earth's biosphere and in the electromagnetic environment. The long-term data sets suggest that the increase in geomagnetic activity and surface temperatures are related (at least partially) to longer-term solar variations, which probably include an increasing trend superposed with a cyclic behavior with a period of about 90 years.

On Thursday afternoon (7th February 2008) a large chunk of the Sun will disappear as the Moon covers it in a partial solar eclipse. This rare event only happens every few years from Gisborne’s perspective. At first a small bite of the Sun will disappear at 4:43pm and then the Moon will progressively cover the Sun until its greatest coverage of 63% at 5:49pm. From there it will move off the Sun until it is all over at 6:49pm.

Explanation: That large sunspot near the right edge of the Sun is actually not a sunspot at all. It's the International Space Station (ISS) and the Space Shuttle Discovery on mission STS-114. In the past, many skygazers have spotted the space station and space shuttles as bright stars gliding through twilight skies, still glinting in the sunlight while orbiting 200 kilometers or so above the Earth's surface. But here, astronomer Anthony Ayiomamitis took advantage of a rarer opportunity to record the spacefaring combination moving quickly in silhouette across the solar disk. He snapped the picture on Thursday, July 28th from Athens, Greece. Launched on Tuesday, Discovery joined with the ISS Thursday, making the already large space station seem to loom even larger.

Close-up videos of the Sun reveal a panorama of constantly bubbling, turbulent gas. Yet this scene of perpetual motion is not the whole story. Scientists using the Michelson Doppler Imager (MDI) experiment on the ESA-NASA SOHO spacecraft have discovered that the surface of the Sun is covered with long-lasting depressions and humps that are very similar to features on the Earth's oceans.

Sunglasses are definitely not suitable for viewing the Sun. They still allow harmful UV light to reach your eyes. Do not use them for viewing either the Sun or the transit of Venus.
