GRAZING LUNAR OCCULTATION, 1998 SEPT 11/12
Richard Miles reports:
A very favourable grazing lunar occultation takes place between
about 00:40 UT and 00:50 UT as seen from south and south-east
England on September 11/12 involving the bright star, gamma Tau.
Coordinates of the central graze track are listed below. The graze
takes place largely along the dark limb of a 61% illuminated waning
Moon.  The Moon will be quite high in the skyCan (27-29 deg alt).
Observers are encouraged to travel near to the graze track and to
begin observing about five minutes before the time listed for the
particular location chosen.  The track passes near Poole,
Winchester, Aldershot, Staines, Epping, Braintree, north of Ipswich
and south of Lowestoft.  Where possible a video record should be
attempted and the camera should also record a time signal before
and after the event whilst the camera is still running. Visually,
the grazing occultation should be capable of being timed visually
using a telescope having a 6cm aperture or larger. The star may
disappear and reappear several times during the course of the
graze, each event should be timed if possible. A tape recorder
would also be helpful - again time signals should be recorded
whilst the tape is still running.  Observers should select
geographical positions such that they are scattered up to 1 km or
so north of the central track, and up to 5 km south of the central
track rather than always be exactly on the track, so as to
adequately map out the profile of the lunar limb on the basis of
the timings made.
Observation reports should be sent to myself and to Andrew Elliott,
the BAA Lunar Occultation Coordinator.
