Ive been interested in the stars since i was about 8 years old. I joined the JAS (SPA) in my teens and started timing Lunar occultations, being spurred on by the then Lunar Section Director Goeff Amery who lived not far away.  I joined the BAA in 1974 aged 23.  Then in 1980 I started visual monitoring of asteroidal occultations using the predictions by Gordon E. Taylor.    I have now recorded more than 30 positive events and been in the shadow of an asteroid for over 500s.

In the last few years i have also video recorded some nice lunar grazing occultations with good timing accuracy.

Professionally I worked in Pharma and later the Agrochemical industry as a physical and analytical chemist, now retired.  I coordinate occultation observing for the Asteroid and Remote Planets Section, and the Lunar Section.  I am a member of the International Occultation Timing Association, European section. (IOTA/ES).

This graze of a 6,7 mag star occured at a  favourable cusp angle of 6 degress (Northern Limit) with the Moon only 38% sunlit. The most interesting aspect was the double star. The telescope was set up in a carefully planed location which was expected to reveal some interesting graze phenomena. I was not dissappointed. On the light curve I have drawn a green line that represents the appearance of the fainter companion (while the brighter one occulted). The red line is both stars having appeared. The whole event lasted was 27 sec
