Sounds like failed bumping episodes.
A quick search on "old faithful diurnal" turns up other examples of "solar powered" activity in the park:
Diurnal Activity of Beehive Geyser, Upper Geyser Basin, Yellowstone National Park, Wyoming.
Geyser Hill Group-Pretty neat, I didn't know that.Some geysers additionally but inconsistently exhibit diurnal behaviors--that is short intervals by day and longer intervals by night.
Actualy now that i've had some time to think about this, It makes sense, and we already had examples of it in the solar system.
Comets have outgassing that is driving by the harsher sunlight in thier environment.
While the Earth's atmosphere does filter out much of that harshness, there is still a lot of solar energy being placed into the ground during day time hours. It only makes sense that cycles of warming and cooling of ground (day/Night) would effect the trapped steam pockets in geyser locations, causing more frequent eruptions during day light hours as heat builds up in the ground.
