I realize I’m growing weary of Haiku.
But still I’d like to express myself in some old fashioned way
And at the same time, try something new.
So tonight, I write in the form of a sonnet
Like the Bard would have, centuries ago.
But when it comes to news, though you might want it
I have very little to report that you don’t already know.
The Observatory continues her graceful figure eight,
SDOGS2 remains watchful and ready for command,
But there are no activities planned for this date,
And thus, the uplink is short on demand.
Thus concludes a nominal shift report:
I have expressed myself, and await your retort.

Eadweard Muybridge is the father of stop action photography. He developed techniques to look at tumbling humans and moving animals. One of his most famous works was to see whether a galloping horse had all four hooves off the ground at the same time. Muybridge set up a series of cameras on the grounds of Stanford University and took 16 photographs that proved the horse gathered all four hooves under its belly at one instant in the gallop stride.
SDO uses similar techniques to make movies of coronal loops, magnetic fields, and prominence eruptions. We also need to ensure we sample the time intervals quickly enough and our pixels are small enough to see what is actually happening on the Sun. Muybridge answered similar questions as he studied animal locomotion.
Muybridge’s photographs are on display through July 18, 2010 at the Corcoran Gallery of Art in Washington DC.
