Watch the 2006 total eclipse with ESA

29.03.2006


On Wednesday 29 March 2006, the Moon’s shadow will sweep over the surface of Earth during the fourth total solar eclipse of this century.


Eclipse of the Sun at solar maximum



The path of the Moon’s ‘umbral’ shadow begins in Brazil at 10:35 CEST and crosses the Atlantic reaching Africa about 11:08 CEST, where it will travel over the northern part of the continent. It next crosses the Mediterranean Sea to Turkey, and then central Asia where it ends at sunset in western Mongolia.

For lucky observers in Egypt, Turkey, Russia, Brazil, Mongolia, Libya, Togo, Nigeria and Chad, the Moon will completely obscure the Sun and cause almost total darkness for a few minutes. This is the total solar eclipse and such an event only happens every few years.


In addition, many countries in Europe will enjoy the spectacle of a partial eclipse. This partial eclipse will be seen within the much broader path of the Moon’s penumbral shadow, which includes the northern two thirds of Africa, Europe, and central Asia.

A solar eclipse occurs when the Moon comes between the Sun and the observer. This happens when the shadow cone of the Moon intersects the surface of Earth, and is observable by anyone within this shadow zone.

Take care!

You need to take some precautions if you want to enjoy watching the eclipse. Looking directly at the Sun can be very dangerous!

Looking directly at the photosphere of the Sun (the bright disk of the Sun itself), even for just a few seconds, can cause permanent damage to the eye because of the intense visible and invisible radiation that the photosphere emits. The retina of your eye has no sensitivity to pain, and the damage may not appear for hours, so there is no warning that injury is occurring.

SOHO and the eclipse

Any total solar eclipse is an exciting opportunity for unique observations from the ground. Free from the overwhelming glare from the Sun itself, the corona that surrounds it is usually the prime target for the observations.

So almost invariably during any eclipse, expeditions go out to whatever sites seem favourable, to capture what may be a once-in-a-lifetime observation of phenomena that are otherwise hidden by the brightness of the Sun.

To make the most of the observations, however, some expeditions are relying on additional data supplied from the ESA/NASA SOHO and other spacecraft, either to determine the pointing of their instruments, for context information to help interpret the data in a broader setting, or both.

Especially in demand are images from the EIT and LASCO instruments on SOHO. EIT observes the storms in the Sun’s atmosphere by ultraviolet light, which is blocked by Earth’s atmosphere.

LASCO is a visible-light coronagraph that keeps the Sun perpetually eclipsed by masks in its telescopes. Viewing a huge volume of space, LASCO can show how features seen close to the Sun, by ground observers during the eclipse, relate to space weather further out.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
