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.
Grimthorpe Handicap Chase Grimthorpe Handicap Chase The Grimthorpe Handicap Chase is a National Hunt handicap steeplechase in England which is open to horses aged five years or older. It is run at Doncaster over a distance of about 3 miles and 2 furlongs and during the race there are 19 fences to be jumped. The race is scheduled to take place each year in late February or early March. Prior to the early 1980s the Grimthorpe Chase was run over two miles and 150 yards. The distance was then upped dramatically nearly doubling to a stamina testing four miles and 100 yards. The
