It is a Supplement 1 to the SECGPN planetary nebula also known as TK Wed, 07 May 2008 22:58:58 GMT Tony Buckley http://tech.groups.yahoo.com/group/amastro/message/21269 http://tech.groups.yahoo.com/group/amastro/message/21269 Alan Prevailing winds, as used heavily in the days of sail are from west to eadt - the so called roaring forties at lat 40 south.

I also plan to go back down in Wed, 07 May 2008 20:50:34 GMT Steve Gottlieb http://tech.groups.yahoo.com/group/amastro/message/21265 http://tech.groups.yahoo.com/group/amastro/message/21265 Last month while I was observing in Australia, I took a look at LMC N49 (= LHA 120-N49), which I believe is the brightest SNR in the LMC.
