RCW 88 of a larger halo of fainter nebulosity extending perhaps out to 10 arcmin. The RCW catalogue states the Hα image size is 3'×2. RCW 88 is located about 3300 parsecs (10,000 light years) from us, though other estimates place this at a closer 1800±300 pc. or 1800±200 pc. Assuming the former distance and the diameter as 5'-6' across, finds by simple trigonometry the true size subtends a minimum of 5±1 parsecs (16±3 light-years.) This small emission nebula shows a mean radial velocity of −18 km.s, and is also a faint radio source that was identified by Lloyd Higgs in 1971.
Cape San Blas Light enclosing a stair cylinder, with the lantern above ground and above water. The 800,000 candela 3-foot 2-order electric light flashes white every 20 seconds and is visible 16 miles (26 km or 30 km). A radiobeacon was established at the station in 1939. As of June 2012, the light has been added to the lighthouse Doomsday List. In July 2014, the lighthouse and two keepers' quarters were moved from Cape San Blas to George Core Park in Port St. Joe.
