fellow students the various intricacies of the transit. |

A
technique which has been used with some success to observe
the transit is the mirror projection one. |

Using binoculars
to observe the Venus spot by projection can be fun, but
getting the Sun right through one ocular can be a bit tricky,
and better have a stable posture so as not to have a dancing
Sun... With fine focusing, the quality of the image is remarkable.
Here again the two sunspots existing at the time of the
transit could be spotted easily once the binocular was put
on a tripod. |

A
small exhibition with explanatory panels was set up next to
the observing area. |

Here we see the (inverted) picture of the "transited
Sun". As a check of the quality of the image, the two
sunspots existing at the time of the transit could be easily
spotted. |

In the early morning just after sunset, one young Sirius member,
bemused by the scene, looks at the tiny Venus spot from the
Ain-Bey sighting site in the Constantine suburb where the
the second contact was timed accurately, |

Quite few eclipse glasses were made available for the onlookers. |

main campus. The circular structure in front is the main library
with his several stories underground. Much farther on the
horizon is the new Tedjini Heddam campus. |

The
image was projected some 15 meters away in a shadowy corner
of the Main auditorium. Venus could be seen but with some
difficulty. |
|
Various
gatherings took place around the watching scopes...
