The Hypoxic Observer© is the official newsletter of The Colorado Springs Astronomical Society. In 1999, the editor was awarded Mabel Sterns Award (first runner-up) by the Astronomical League for outstanding newsletter editing.

The Hypoxic Observer© is available as PDF (Portable Document Format) documents and is distributed each month, free of charge, through this website. The added bonus of the PDF version is that it is in full color!

To view the PDF version of the newsletter, you must have Adobe Acrobat Reader 4.0.1 or later installed in your system. If you do not, you can download it now from Adobe Systems for free!

Below is a list of newsletters available for download. These PDF files will open in the same browser window (if your browser supports PDF files) so you’ll need to hit the browser back button to return to our website. If it opens in your browser window you can save it to your computer from the PDF menu. Thanks!
