I chose to group these pictures because they were all taken consecutively.

The story behind these images is interesting...
My Father-In-Law passed away a number of years ago.  Since then, the family has moved around a bit.  The clock in the pictures was the PRIZED possession of my Father-In-Law.  No one was allowed to ever touch it, wind it, or anything.  This clock stopped running.  Just recently, it began running again...It has not been running for a number of years (5 years I believe).  I recently visited my family in their current home.  They related the story of the clock to me.   I remember how he revered the clock, but was unaware of it not running then starting up again.  They asked me to casually investigate - which I did.  I shot these pictures.  They were shot consecutively and what appeared was compelling to me.  I do not normally consider orbs to be a validation of a haunting but these were intriguing to me.  I shot others, after these, and there were no shadows, no orbs, and no light anomalies.
I truly believe my Father-In-Law to be there watching over his clock, but more so watching over his wife, because that is what he knew best in life.
The images show 2 'garden variety' orbs, then a 'gel' orb (#3), and then a light anomaly (#4), I could not find explanation for. 
I had no readings from the EMF detector.  I did use a digital voice recorder and found nothing unusual.  I found nothing unusual with the digital thermometer. 
A lot of the time, orbs can be moisture captured in a flash, but the area here is a dry, desert area.  There were no bugs flying around.  I came up with no explanation for the images.  Please comment.
Oh, and you can see the times the photos were taken...just look at the clock!
