For over 70 years, March 23rd has been designated World Meteorological Day. Here are the arms of His Majesty's Astronomer Royal for Scotland, a post created in 1834 and granted arms in 1996.
Bleu celeste, on a pale Or voided Sable between two James Short reflecting telescopes, that on the dexter in bend sinister and that on the sinister in bend, both mounted upon tripods Or, eight mullets Argent (representing the constellation Orion) and on a chief Azure with a fillet in base Or a saltire Argent and in the centre point an open crown Or.

The arms are unusual in some respects - the fillet or thin fess only occurs in a few arms in the Register while the specification of two shades of blue is unique, clearly as the Scottish saltire needs a dark blue and the sky has to be celeste.
