I get 1.2' away using a Palm app. Well done on the observation ! Low altitude observations will do in a pinch. Even sunrise and sunset timed observations without a sextant will get it done. On the ultra low observations there is the chance of abnormal refraction so use caution. I draw the line at about 4°. Anything below this will show an unfiltered Sun in the horizon mirror.
