Summary:

Naked eye observation

We had an opportunity to wave at our friends on the ISS as they flew in an

arc over MDRS. Beginning at 18:46 PM on Sol 10, Commander Scott Kelly and

his crew were visible for 3 minutes at a maximum height of 86°, appearing

24° above SW and disappearing 28° above NE, over the hab. The visiting

photographer captured the ISS flyover with his camera.

Objects viewed: International Space Station

Problems encountered: None.

Summary:

Visual Astronomy

I practiced calibration using the two-star alignment method. It was

successful but I would like to repeat the steps with additional calibration

stars for accuracy. I performed systems checks of the observatory dome,

shutter, power and lighting systems as well as visual inspections of the

telescope mount and lenses. Replaced the burnt out red light bulb and

placed the spare in the observatory storage drawer. Dome was able to rotate

a full 360 degrees. The clacking noises observed by the last crew during

telescope slewing were not heard but I will keep an ear out for them.

Imaging Astronomy

I mounted the CCD camera to try and image one of the five visible planets

as they are currently aligned in the SE-SW sky arc. Due to dropping

temperatures, I was unable to stay outside long enough to focus correctly

in the CCDOPS software but it served as a good practice for setup

procedures and confirming equipment and connections are working correctly;

the telescope and the computer are able to successfully communicate.

Objects viewed:

Using 2-star alignment and calibration method:

Pollux

Rasalhague

Ghost of Jupiter Nebula

Problems Encountered: Ice on top of the dome shutter caused it to stick at

first opening. After waiting for it to warm up and nudging it, I was able

to fully open the dome shutter and rotate the dome as needed. Directly

below the shutter closure point in the dome home position, ice had formed

on the floor of the observatory while not in use. I was unable to fully

close the shutter at the end of my session as it had either frozen open in

the cold weather or the shutter battery box had drained while open. I let

it sit in the sun (with telescope stowed in home position and covered) for

2 hours after sunrise and was able to fully close the shutter and secure

the observatory. Photos of shutter frozen shut and ice on floor are

attached.

Naked Eye Observation:

Our rotation lines up with the best time for all of 2016 to see Mercury,

Venus, Saturn, Mars and Jupiter together. All five worlds visible 80

minutes before sunrise began at 07:26. The moon was paired up with Saturn

this morning.

Problems encountered: Extremely cold temperatures and fatigue by crew

prevented prolonged enjoyment of this astronomical phenomenon.
