I for one welcome the idea of measuring time in lightpetametres ;)

(that's about 38.6 days for the curious)

The problem is with what a year is, which is arbitrary to begin with, but worse still, a year is not constant. The momentum of every planet is affected by the gravity of every other planet, leading to fluctuations in solar orbital speed, which means a full orbit is likely never the same period as the previous or subsequent orbit. Maybe these fluctuations are small, but light travels so fast that over long distances it is sure to be significant. Thus the definition of a light year is defined as the distance light travels in a Julian year, 365.25 days, but this just pushes the error down to a different measure, because days are not constant either. Since the speed of light actually is constant, maybe we should define years and days by the speed of light instead of vice versa.

Astronomers also use angstroms when refering to the filters used for solar observations.

Just because they're pretty, here's a link to the SDO gallery: https://sdo.gsfc.nasa.gov/gallery/main

Also, the SDO takes an image through each filter as it rotates through the filter wheel, IIRC, it takes 15 minutes to rotate through them all. They are then made available for each filter at different resolutions. Being the hacker-ish type, I wrote a script to use curl to download the image sequences for chosen filter/framesize for the sun's full rotation to create a one day timelapse.

And if used literally, parsecs (parallax arc-second) should have smaller values the father away something is!
