Provided a Conformation Check on a Work Card for removal of tools and materials and was later discovered that Speed tape was left on the Right-Hand (R/H) Static Port. The work was performed at the Line at night and I; Mechanic X; was working with Mechanic Y. The [Speed] tape was not seen during my walk around due to not having a red flag on it and Speed tape does not stand out well in that spot. A red flag should always be used when blocking any Static Port.
I did a Check on Aircraft X; an Embraer-145 aircraft and signed-off the Work Card.  Became aware that Speed tape was left over the RVSM Port. There was no damage to the aircraft; no delay; no emergency declared. Aircraft flew four legs [flights] and a pilot found it [Speed tape] on the walk around.  Communication Error on me and other mechanics.[Recommend better] communication between other mechanics. Aircraft in service at gate. Evening Shift.
Four Line Aircraft Maintenance Technicians (AMTs) including a Lead Technician; report about their involvement with an Embraer-145 aircraft that flew four legs with the Right-Hand (R/H) Static Port covered with Speed tape.
