It depends on whether you are living in the bush, the suburbs of the heart of town. Light pollution is so bad in some places, you can only see the brightest stars. Want to be involved in some participatory amateur science? Then get involved in this sky survey that my year 9 Research Science and Technology <SPAN>student</SPAN>s are running as part of the GLOBE project this month.<BR><BR>Learn, Observe, Report and Map! <A

Between now and March 21, go outside at around an hour and a half after sunset, possibly a bit later. Stand in a spot where street lights or neighbours outdoor lights won't get in your eyes and let your eyes adjust for a few minutes (or more, after looking at the<SPAN> computer screen </SPAN>it can take up to 5 minutes for my eyes to adjust). <BR><BR>Compare what you see of the constellation Orion to their <A title=http://www.globe.gov/GaN/observe_magnitude.html href="http://www.globe.gov/GaN/observe_magnitude.html">starcharts</A>, (see map at <A title=http://home.mira.net/~reynella/skywatch/ssky.htm#Stars
href="http://home.mira.net/~reynella/skywatch/ssky.htm#Stars">Southern Sky watch</A>) or print out the maps in the attached Family <SPAN>Activity</SPAN> pack) and submit your observations to this link:<BR> <A href="http://www.globe.gov/GaN/report.html">http://www.globe.gov/GaN/report.html</A><BR><BR>If you are using a torch to read the Family <SPAN>Activity</SPAN> Pack maps, remember to put some red cellophane over the end so as to not destroy your night vision. Simple as that, and you are contributing to our understanding of light pollution as well a doing a bit of amateur science.<BR><BR>(share me your location and finding, I hope to use it with my year 9 Research Science class to compare results, data quality and validation etc..)<BR clear=all><BR>-- <BR>Roland Gesthuizen - ICT Coordinator - Westall Secondary College <BR><A
