Today the planet Uranus will pass through opposition, directly opposite the Sun in our sky. The planet will be well placed for observation all night long, rising at sunset, transiting at midnight, and setting at sunrise. If you are looking to observe Uranus, it is currently shining at magnitude 5.7 in the center of the constellation Pisces.
As the outer planets Uranus and Neptune move so slowly across the sky, the timing of oppositions is driven by the Earth’s orbit and occur each year at nearly the same time. The orbital period of Uranus is 84.1 years, taking the better part of a century to circle the celestial globe once.
It did not look like it was going to be a bad week. The schedule was for a light week with nothing serious envisioned. Better yet, Tuesday was scheduled to be our departmental retreat, a day at the beach with the operations crew, all good.
One. Deb is having a bad spell. With little warning I took off Monday afternoon to drive her down to Kona to spend a couple hours in the infusion lab for medication.
Two. Monday would just not die easily… The phone calls began just after sunset. The Keck 1 hydraulic bearing system would not come on properly, shutting down just after the main pump came online. It became quickly apparent that I would be joining John and Justin for a trip to the summit in the middle of the night.
