Ten-Years Ago Today. Poppies and Lupines at Christ Church Cathedral, Stanley. (22-Dec-2014, Falkland Islands)

Silhouettes of an Airplane and Jets Passing in Front of the Sun.

Today, I captured images of an airplane and several jets transiting the sun while looking at the sunspots (we are at or near the solar maximum). I was observing the sun with a Vespera Classic and a Vespera Pro telescope each fitted with a solar filter. The exposure time for solar observations with the Vespera Classic telescope is 250 microseconds (1/4000 sec) and with the Vespera Pro telescope is 1400 microseconds (1/714 sec). The Vespera Classic takes 51-52 solar images per minute and the Vespera Pro takes 8-9 solar images per minute.

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail much shorter. You may need to look closely; the comet is in the center of the frame. The magnitude is now 10.9. The slideshow displays the 32nd, 64th and 96th stacked composite image (5 min 20 sec, 10 min 40 sec, 16 min). In the last two images there is some movement of the comet head.
