quadruple dips

• by williamaskew

  I keep running into these quadruple dips usually followed by a quadruple flare. Can anyone tell me what causes these?

  This is a glitch visible on lots of stars in Campaign 4 (BKJD 2276.5 - 2277.5). Kepler fires it thrusters about every 6 hours to compensate for drifting. Most of these movements have been corrected in the light curves on Planet Hunters, but it looks like something went wrong here.
