The year 1986 in images and words
During the 1986 Perseïd campaign Bauke and I were back in Puimichel. There was also a large group of Belgian meteor observers. After four clear nights there was a period of four nights with unstable weatherconditions. Also the first part of the night 11/12 August was lost in heavy thundersstorms. Eventually the storm complex moved away to the northeast and within a few minutes a heavy mistral was blowing and the sky was crystal clear (lm 6.9).

Picture 2: the flat roof of the 1 meter telescope building provided a good view on the heaven's...


Picture 3: a so called Purus Omloop Mount.


Picture 4: early morning hours of August 13, 1986. Orion and Taurus rising in the east...


Picture 5: August 14, 1986: a Perseid with two flares of magnitude -4 in Ursa Minor. The first "flare" is not a flare but the star Polaris, what a coïncidence! Camera: Canon T70 with a Canon FD 50 mm F1.4 ssc lens mounted on the Purus mount.


Picture 6: August 13, 1985: during dusk a Perseid of magnitude -3 near Polaris. Camera: Canon T70 with a Canon FD 50 mm F1.4 ssc lens mounted on the Purus mount.

The next night was spotlessly clean with a strong mistral. Thanks to this clear sky ( lm 6.9 a 7.0) I saw the Perseid hourly counts go far into the 100. Calculations showed, that the ZHR was around 80, a normal level for the Perseids. I had three Canon T70 camera's equipped with commando backs and captured 80 meteors. See also my photo page.


Picture 7: november 1986, the 1 meter building is finished....

In the period from October 26 to November 8, I was again in Puimichel, along with Bauke. During this period we could observe two major meteor streams, the Orionids and Taurids. This campaign was to Dutch standards a big success. The last night we saw a sporadic fireball of magnitude -8. This night ended my career as a very active meteor observer. I had decided to quit with the observation of meteors. The last three years I had seen so much that I literally was saturated! In addition, I saw not the purpose of observing the annual meteor streams year after year. Now I know better....

In 1987 I did nothing at all on the meteors area and later that year I met my wife. But, halfway 1988 the meteor bug striked again. During that and next years I did some meteor observations, but at a lower level than during the previous years.
