              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tonight was the night of giving! The sky gave us (mostly) clear views of the stars, with good seeing and an easy breeze.  CU02's object became quiet low and she donated 19 of her minutes to UW02.  UW02 could not go far into twilight and he too donated the hour before sunrise. But where was there an observer to be found who could use such time?  Venus was not up. Ah! But the Kepler field was rising! And NM07 was able to drop in and gladly accepted the twilight time that was donated. And was happy.
No problems tonight.
-----------
Once there was a telescope...
and she loved the observers.
And everyday the observers would come
and they would gather the photons
and make them into data
and play PI of the lyman alpha forest.
The telescope was happy.
But time went by.
And the night grew colder.
And the telescope was left alone.
Then the next observer came to the telescope
and the telescope said "Come, observer, come and
climb up the skies and slew from my
azimuth and grab photons and play in my
sky and be happy."
"I am happy to climb and slew" said
the observer.
"I want to see things and have fun.
I want some funding."
"I'm sorry," said the telescope, "but I
have no funding.
I have only mirrors and photons.
Take my photons, observer, and publish them in
the city. Then you will have funding and
you will be happy."
And so the observer gathered her photons
and carried them away.
And the telescope was happy.
But the observer was not on for very long
and the telescope was sad.
And after a long time
an observer came back again.
"I am sorry, observer"
said the telescope, "but I have only twilight
left to give you."
"I don't need very much now," said the observer
"just a couple spectra before I rest.
I am very tired."
"Well," said the telescope, slewing
herself up as much as she could,
"well, some twilight spectra is good for science and resting
Come, observer, sit down. Observe and rest."
And the observer did.
And the telescope was happy
