Solar eclipse 2012 – Event facts

2001 eclipse in Zambia

Phenomenon

Moon's shade strip schemaA solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun, as seen from Earth. This can happen only at New Moon (Moon between the Sun and Earth) and if the Sun and the Moon are perfectly aligned as seen from Earth. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun appears obscured. During the brief moments of totality, the naked-eye planets and the brightest stars appear in the sky, creating an artificial “night”, although the lighting conditions are more reminiscent of advanced twilight than deep night. Around the full circle of the horizon the colours are similar to the colours of a sunset, because at such large distances, the eclipse is not total.

Expedition

Observation sitesGLORIA will follow the event from three locations in the Queensland (see figure): one located on the coast (G3 near Oak Beach) while the other two will be in the inner zone (G2 at 81 Rt road, G1 in Mareeba town). At these sites the totality duration will be approximately 2 minutes. The time chart below shows all the relevant times of the event. Expedition leader, Dr. Miquel Serra-Ricart, and Dr. Vanessa Stroud, astronomers of IAC, Canary Islands, will provide commentary of the live event in Spanish and English. The non-profit Shelios association (shelios.org) is responsible for the planning and logistics.

Broadcast

The total duration of the eclipse is 1h 50m and the retransmission is performed in two ways:

1. Live: There will be a live connection with a total duration of 15 minutes to encompass the second (C2) and third (C3) contacts (see table times below) and with streaming images of the Sun from the three locations G1, G2 and G3. From location G1. Find the details in this document.

Connection: Contacts 2 and 3 – 13th November 20:30 to 20:45 UT (21:30 to 21:45 CET).

  Note 1: The local time at the observing sites will be 6:30 to 6:45 Australia EST (14th November). See here.
  Note 2: UT – Universal Time; CET – Central European Time.

2. Time-lapsed: From 19:45 UT on November 13th, and every five minutes thereafter, the image of the Sun (partially eclipsed by the Moon) will be refreshed from the three observation points.

The broadcast can be followed on the GLORIA web portal live.gloria-project.eu.
