This is the latest from the British Astronomical Association...
----------------------------------------------------------------------------------- In the past 24 hours, a spectacular event has taken place involving the periodic comet P/Holmes (17P). Its predicted brightness is about magnitude 17 however last night it was discovered by the Spanish amateur, Juan Antonio Henríquez Santana to have undergone a tremendous outburst having attained magnitude 10 at that time (Oct 24 0h UT). It was a similar outburst in 1892 that led to its discovery. Latest reports (Seiichi Yoshida, Oct 24 13h UT) indicate that it is stellar in appearance and 3RD MAGNITUDE in brightness: so bright in fact that it is readily visible to the unaided eye. That's almost one million times brighter than normal ! Fortunately for UK-based observers the comet is well placed for observation and is visible throughout the entire night. Its position at 0h UT tonight (Oct 24/25) will be: R.A. 03h 53.0m, Dec. +50 08' Its appearance will probably be that of a fairly bright naked-eye star moving at an apparent rate of close to 10 arcmin per day at PA 298 deg. It is currently 1.63 AU (245 million km) from the Earth. ------------------------------------------------------------------------------------------------------- Of course, after 3 gorgeously clear nights here in Kendal it's totally (chink) overcast tonight... -------------------- |
