Annular eclipse at the Albuquerque Balloon Fiesta 10/14/23 part III: super-annular eclipse montage and animations

 You may recall that there was a supermoon in late september.  the corollary to this is a "micro-moon" crossing the face of the sun during the solar eclipse at the subsequent new moon, resulting in an annular eclipse rather than a total eclipse 😢

or, to look on the "bright side" a super-annular eclipse with the widest band possible.

in creating a montage of the partial phases, i viewed the annular phase and decided on a clock-like arrangement with small images of partial phases forming a ring around the annular eclipse.  after meticulously arranging the partial phases, i looked at what i had done...not exactly what i was going for, but i'll take it.

flower power!

the disturbance mid capture above is likely due turbulence from the burners firing off in the field at annularity :(

if  you look at the final images of annularity, you'll note that the moon does not contact the sun evenly.  mountain peaks contact the sun first:

by offsetting each image (captured at 4 frames per second) by 1 pixel, one can generate a magnified image of the lunar surface:

  1. Really like your final composites. Lot of work went into that!
