Sounds like he difference between magnetic and true. In Salt Lake that difference is about 14 degrees. The compass in the phone is almost surely magnetic, but the software should be able to compensate by using the GPS for position. Magnetic variation is pretty well known. ________________________________ From: Chuck Hards <chuck.hards@gmail.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Thursday, December 22, 2011 7:09 AM Subject: [Utah-astronomy] Google sky map The sky map seems to be offset from the actual direction one faces by 15-20 degrees or so. Does anyone know if this is intentional? Perhaps in order to not block the view with the phone itself? _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
