2. GLOBE AT NIGHT: The global citizen-science campaign on light pollution, known as GLOBE at Night (http://www.globe.gov/GaN), started on Monday, March 16th and runs through Saturday, March 28.
People around the world are invited to participate in GLOBE at Night, which is part of the International Year of Astronomy (IYA2009) "Dark Skies Awareness" Cornerstone Project. IYA2009, as you know, is a global celebration of astronomy and its contributions to society and culture, marking the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei.
For more information, and to learn how to make and report measurements, see www.globe.gov/GaN
To make a measurement, you must wait for astronomical twilight (approximately 20.30 in the UK this week) for the sky to be properly dark, look in a south westerly direction and look for three bright stars close together in a straight line. If you can spot it, you've found Orion's belt.
Go to http://www.globe.gov/GaN/observe_finder.html for further tips.

3. ISS EVENING PASSES: The International Space Station which recently had a close miss with a piece of space debris, will be visible in our evening skies from March 18. The largest spacecraft ever built, it is currently hosting the Space Shuttle Discovery which was launched on March 15th, on a construction mission to complete the power grid of the international space station. This 125th shuttle mission will deliver and install the final segment of the station's truss backbone and unfurl two giant solar wings.
