20.03.11: An Occultation Update.

This Super-moon Sunday, we’d just like to give a brief self promotional shout-out to an astronomical success we had last weekend. Last Sunday we managed to catch the occultation of the 4th magnitude star Mu Geminorum by the waxing gibbous moon from Astroguyz HQ here in Hudson, Florida;

24.9.9; “Anti”Crepuscular Rays!

Sometimes near-sky astronomy happens during the strangest of moments. Over the past week, we’ve been treated along the Florida Gulf Coast to some fine displays of crepuscular rays during sunrise and sunset. Generally these shining rays can be seen streaking through the crags and valleys of mountain ranges and ridges when the Sun is at a low angle. In the “flatland” of Florida, however, these occur for a different reason; scattering of sunlight through the edges of large, fluffy cumulus clouds. Humidity, dust and sun angle can all make for a swiftly evolving scene. This mornings’ display from Astrogyuz HQ in Hudson, Florida was one of the best I’ve seen, and even included what’s loosely termed “anti”- crepuscular rays, or rays streaming opposite to the direction of sunrise and seeming to converge towards an imaginary vantage point in the west. This is a fine example of an optical illusion; our minds tend to project the sky as a big, upside down bowl above us, and hence especially long or bright striped rays can actually appear to converge opposite to the Sun!

Antares Occultation; a Semi-Success.

Just a quick mention that we were successful in viewing the Antares occultation by the Moon from Astroguyz’ HQ here in Hudson, Florida. Alas, no sighting of a greenish tinged Antares B (or the planet Krypton…) was recorded. However, the ingress made for a cool video…

2009: The Year of Astronomy.

This is a shout out to the world; 2009 is the International Year of Astronomy. Check with your local astronomy club, observatory or planetarium to find out what events are near you; if they aren’t planning anything, ask them why not!
