Observed from White Rock, New Mexico, USA on 14th October 2023. Purposely positioned away from the centre line to observe an asymetric annularity - still giving a generous duration of 3m 1s. Clear sky. Canon 700D DSLR used on a 60 mm f/6 refractor with a Thousand Oaks Solarlite Solar Filter.

This eclipse was one saros period after the 2005 annular solar eclipse, which I observed in Spain.
For the 20th May 2012 annular eclipse observed from east of Kanab, S.W. Utah, USA in the Grand Staircase-Escalante National Monument. Perfectly clear sky for the eclipse.At this site (very near the centre line) the magnitude was 0.963, giving the duration of annularity of 4m 31s. 70 mm refractor (Pronto) at an effective focal length of 528 mm.

Right: Still partially eclipsed while setting behind a distant mountain.
Bottom: A mosaic. Notice the dimming and reddening of the Sun, caused by more atmospheric extinction, as it neared the horizon in the final frames. Also the horizon is encroachingin the final frame.
Observed from Jalón, Alicante province, Spain on 3rd October 2005. Some cloud present at first which obscured the First Contact, but the sky cleared nicely soon after and remained so for the rest of the eclipse.At this site the magnitude was 0.949, giving an annular duration of 4m 10s.
