Turntable Hum

Hello all. I have a very unusual issue that just started a couple days ago. I noticed some hum when my cartridge came in contact with a record (Project Debut Carbon with an Ortofon 2M Blue) turntable on.  The hum isn't as loud as say when you remove one channel of your interconnect and also seems to occur when I touch my Onzow stylus cleaner to the stylist.  The problem did go away briefly yesterday afternoon, then came back, then went away again last night.

Any thoughts?
