Typical sequences and mnemonics are:

• The spectral sequence O B A F G K M. The classic mnemonic is Oh Be A Fine Girl, Kiss Me. You may replace girl with guy, depending on your sexual orientation, without changing the sense of the mnemonic.
  Sometimes, astronomers extend the spectral sequence by adding the R N and S stars, which are cool variants of M giants. Extend the mnemonic by adding Right Now, Sweetie!

  The original sequence has been extended to include brown dwarfs, with spectral types L, T, and Y.

  Other favorite mnemonics for the spectral sequence include:
  Old, Bald, And Fat Generals Keep Mistresses ,
  Oh Boy, An F Grade Kills Me., and
  Only Boring, Astronomers Find Gratitude Knowing Mnemonics.

  Can you do better (previous winners are listed below)?

  Can you create a mnemonic for the full O B A F G K M L T Y spectral sequence?

• The planets, in order of mean distance from the Sun, are:
  Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. The classic mnemonic for remembering this sequence, back when Pluto was a planet, is
  My Very Excellent Mother Just Sent Us Nine Pies.

  What can you suggest? If you think Pluto is not a planet, drop the P.

• The colors in the rainbow (the optical spectrum), Red, Orange, Yellow, Green, Blue, Indigo, and Violet are remembered in the classic mnemonic ROY G. BIV.

• The electro-magnetic spectrum, Gamma-ray, X-ray, Ultra-violet, Visible (or Optical), Infra-red, Sub-millimeter, Radio (GXUVISR) needs a mnemonic. (GXUVISR). The X will make this difficult!
