White light in sky?

White light in sky?
Location: Hudson MA

Time: 7pm

I observed this light for about 30 minutes waiting for my husband to leave the store. It was so bright and the sky was really dark, I couldn’t see any other lights. The white light didn’t move at all! My mom about 20 minutes away also observed it and thought it was abnormal looking. Does anyone have any ideas? 

Thank you so much!
