If you use the contents of an Observatorio ARVAL page in your Web site,you must credit it and link back from your page to ARVAL's original page.
ARVAL's Web site is dedicated to propagating astronomical information since February '96.
All of it is bilingual (Spanish - English), except for the 'Astronomía Caraqueña'
section, which contains local astronomical information centered around Caracas, Venezuela.
The emphasis is on the wonder and beauty of astronomy.
Observatorio ARVAL was retired from www.arval.org.ve by anonymous interests
on September 1 '01,
having served more than 65,000 visitors and answered more than 700 messages from them.
But I'm pleased to announce that since Sept. 26 '01 you can browse the pages of Observatorio ARVAL in its new Web address, at www.oarval.org, thanks to Roger Curry and David Knighton of the Northeast Florida Astronomical Society (NEFAS).
If you use the contents of an Observatorio ARVAL page in your Web site,
you must credit it and link back from your page to ARVAL's original page.
The background on these pages is black,
to remind you that astronomical observation
is only really possible from dark sites,
that let you see a black sky.
One of the main enemies of astronomers is light pollution.
Do not allow light sources under your control to illuminate the sky!
It is a waste of resources that helps nobody, but does hurt many people!

In these pages, the word "billion" indicates one thousand millions;
Not a million of millions, like "billón" (in Spanish).
This site is designed so that its pages are easy to save and read off-line,
as some pages are too dense to just browse.
All .htm text files, .gif and .jpg graphics, are in just one directory.
