Observation 3.2

It was 10:40 p.m. on 2/15/11 and was observing the night sky.  Not very many stars were visible but I was able to locate Canis Major by means of the star Sirius and the constellation Orion.  The moon tonight was beautiful as it appeared to be a full moon and it was shining very bright.

APOD 3.3

This picture shows a runaway star, Zeta Ophiuchi.  This star is about 20 times more massive than our sun and it is producing an interstellar bow wave or bow shock.  This incredible picture was captured by the WISE Spacecraft.  Zeta Ophiuchi is traveling at about 24 kilometers per second.  Its strong stellar wind compresses and heats the interstellar material causing it take the shape of the curve.  The only hypothesis for why this star is moving like this is that it was once a binary star and the other star was more massive and it exploded as a supernova.  This supernova then sent off Zeta Ophiuchi to its current motion.

Observation 3.1

2/1/11 7:35 pm 

At about 7:35 I went outside of my house to prepare for the flare.  I looked in the southeast direction and located the constellation Orion.  I then located the two references stars, Sirius and Rigel.  I then waited for the flare and then a little past 7:40 a bright red light appeared in the sky and it continually got brighter for a few seconds and then quickly faded back out.  This phenomena, the iridium flare, was really interesting to see.
