Green orb appeared near Sun…

On March 31, 2015, an inhabitant of Trenton (in the province of Ontario, Canada) was walking his dog when he has noticed the Sun appeared weird. So, he has taken some photo. On his images, he noticed a curious green orb. What is it?

Witness statement:

Walking my pup Ruby...the sun appeared weird with a great halo surrounding it and what appeared to be an electrically charged arm of the sun reaching out like a beam to a spot to the right and that opened up to a rainbow...I found this interesting...I took out my BB and took 4 pics...the 1st 3 were taken quick...not looking at sun directly...too bright...the 4th pic was last taken when I rounded a corner a few minutes after...

I never seen the greenish orb in air...just took pic of it was a shock to see it when I looked at the images...the Trenton Air Force base is 2.8 km west of the pics taken...I am retired military...could be something could be nothing!
