Observations of Venus

On Friday, May 21, in a prelude to the Venus Transit, the 2-day old
Moon covered Venus’ very slim crescent and hid the planet from view
for observers from Europe to central Asia. Many in central Europe,
e.g. those near the ESO Headquarters in Garching near Munich
(Germany), were frustrated to see clouds moving in during the hours
before. However, others were able to make fine observations of this
event, see e.g., the photo-montage by Jan Vesely and collaborators of
the Public Observatory in Hradec Kralove (Czech Republic) and the
short video prepared by Herbert Raab of the Linzer Astronomische
Gemeinschaft (Austria). More photos are being added to the VT-2004
Photo Archive as they become available.

At the time of this “Venus Occultation”, Venus was at a distance of
approx. 50 million km from the Earth. A fictitious observer, located
just outside the dense atmosphere above Venus’ southern pole would
have seen the Earth partly covered by the Moon. The drawing also
illustrates the relative sizes of our planet and its companion.

The next Venus occultation will take place on November 10, 2004, and
be visible from Australia. On that date, Venus will be about 194
million km from the Earth and will therefore appear nearly four times
smaller than this time.

Enjoy the transit!

Useful advice is now available at the “Day of the Transit” area
(www.vt-2004.org/transit/) for all who want to partake in this unique
celestial event on June 8, 2004, and who are not professional or
amateur astronomers. The step-by-step join-the-transit explanations
contain plenty of ideas and suggestions for how to get the most of
this occasion!

The pages, chronologically arranged, carry the titles “Beginning now”,
“Ten days before”, “A few days before” and “THE DAY!” and provide
guidance on how to be well prepared for the event.

TV Film about the Venus Transit

A preview is now available of the first part (about 1/3) of the 28-min
TV-film about the Venus Transit and the VT-2004 programme, currently
in the final production stage in the Czech Republic. It concerns
observations of the transit and the involvement of school students and
their teachers. The preview may be downloaded from the VT-2004 website
[MPG – 83.4 Mb; 11 min; English version], together with an English
transcript [Word – 40k and PDF – 80k]; and also from the special page
at the website of the VT-2004 Czech Node.

The producers will be glad to discuss the possible use of this material
by other broadcasters. Interested parties may contact Ms. Sarka
Spevakova, Herafilm (Prague), by Email: sarka.spevakova@popularis.cz or
mobile phone: +420 724 348 388.

Activities at the VT-2004 National Nodes

Many VT-2004 National Nodes have been extremely active during the past
weeks, preparing for the Venus Transit in their respective areas in
different ways. On most of the corresponding websites, detailed
information is now available in the local languages, reflecting the
broad international scope of this public programme.

A look at these websites will reveal the enormous width of the
activities and numerous links across the borders. In many places,
there will be references to historical expeditions to the
corresponding sites, e.g. in northern Norway, Siberia and Tasmania; in
at least one place, a telescope, used during observations of the two
Venus transits in the 19th century, will again be on display.

Special efforts have been directed towards the schools and it is
gratifying to note that they have clearly been successful – a very
large number of classes all over the continent are now preparing to
witness the transit, most also doing their proper observations. For
this, the VT-2004 educational materials have obviously been of use,
especially since translations into a large number of languages are now
available via the National Nodes.

VT-2004 Observing Campaign

More groups and individual observers have registered with the VT-2004
Observing Campaign; the count by May 21 was 623 and rising rapidly. Of
these, 203 were school classes, 226 were individuals, 125 were
astronomy clubs and 69 were others. 89 countries are now represented,
from Afganistan to Vietnam (alphabetically), Norway to South Africa
(North-South) and Mexico to Australia (West-East).

The introductory page for amateur astronomers has been updated with
more useful links towards the many pages at the VT-2004 website that
describe fine opportunities for observations of the Venus transit, as
well as interaction with the general public. As members of the local
communities and present in virtually every city on all continents,
amateurs will have great opportunities to interact with their fellow
citizens on this widely publicized occasion.

Among the new and very useful features is the “STOPER” software
[ZIP-file – 704k], developed by Arkadiusz Dudka, active member of the
VT-2004 programme in Poland. This programme mimics a traditional
stopwatch and allows precise time measurements to be made with a
PC. It greatly facilitates the timing observations during the transit
by means of which the distance from the Earth to the Sun will be
determined. This software may be distributed as FREEWARE, provided the
author and VT-2004 are credited.

CD-ROM – “Venus’ Rendez-Vous”

A unique CD-ROM has been produced by the Paris Observatory with more
than 10,000 fascimile pages of historical documents related to transit
expeditions and observations, cf. the description with some examples
of the pages. It includes early texts from the 17th century, as well
as the reports of many expeditions in the 18th and 19th centuries,
together with numerous, fascinating illustrations.

The major part of these documents comes from the extensive library of
the Paris Observatory. Access to the facsimiles is either by starting
from a chronological list, from the titles of the books and periodicals
concerned, or from a text of comments that guides the reader towards the
most interesting pages. The comments and the presentation are provided
in French and in English.

The production of this CD-ROM was supported by Observatoire de Paris,
by CNRS and by the European Commission via the VT-2004 program. More
information, also about how to order it, is available here. It is also
on sale at EDP Sciences at a price of 25 Euros.
