Here's a full sun blink between a Big Bear GONG H-alpha image

and an SDO/HMI continuum image both taken at ~2030 UT on 2024

February 12.  The GONG image used is 2048x2048 pixels at

~ 1 arcsec/pixel while the SDO/HMI image is 4096x4096 pixels

at ~0.5 arcsec/pixel.  To get them on the same scale the HMI image

was binned 2x2 to get it to 2048x2048 at ~1 arcsec/pixel and then

this was resized by a factor of 0.93.  This latter factor will change

during the course of the year as the instrumental distances from

sun changes.  IMPPG was used to register the two images and

Movie Maker was used to make the blink.

 

Cheers,

SgrB2
