RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Closest approach of Mars tonight - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

If you have any interest in astronomy, you won't want to miss the opportunity to view Mars tonight as it completes its closest approach to Earth in 60,000 years. From the U.S. eastern seaboard, Mars rises at dusk and is well over treetops by midnight. The new moon tonight will make the skies nice and dark. Mars is so bright now that you can't miss it as long as there is not thick overcast. If you're lucky, you'll spot the white south polar ice cap.

Anything less than about a 6" telescope won't reveal much other than a bright red disk, so don't expect NASA quality images. Many years ago, when I had an 8" Newtonian on an equatorial mount, I was able to see the polar ice cap line, but never anyhting like the "canali" observed by Lowell.

Anyway, a good pair of binoculars will turn up a very bright Mars, enough so that if you stare at it for a few moments with one eye closed and then look away, you'll notice how one eye is dark adapted and one isn't.

Here's a good link to Sky & Telescope
