Ermelo, the Netherlands (52.2 north, 5.4 east)

The year in images and words
An excellent year. With regard to the number of hours of observations, it is even the second year after 1984. A successful Lyridmaximum is observed from Ermelo and we had many clear nights in May. During my vacation at Chios Island (Greece) I observed eight nights. I saw activity of the southern delta Aquariids and the Capricornids.

Of course, the Sino Dutch Leonid Expedition 2001 to China, was the highlight of the year. We (=Jos Nijland, Arnold Tukkers, Casper ter Kuile, Robert Haas, Michel Vandeputte and Sietse dijkstra) stayed in the period of November 15 to 20 at China's largest optical observatory near the town of Xinglong. It was the second time I was staying at a professional observatory and could make use of the infra structure (accommodation, food, internet, computers).
The team was split into three groups. They would observe from the radio observatory near Miyun (Jos and Sietse) and a hotel in the village of Panshan (Robert and Michel). This to do simultaneously photographic and video observations. I stayed at the XingLong optical observatory. After the first night there was a panic call from Robert Haas from Pamshan. There was too much light and air pollution. Astronomer Jin Zhu made a few phone calls and that resulted in the moving of the hotel guests to another hotel, extinguishing the coal stoves in the village and the closing of a factory after 22:00 local time. Try that to settle in the Netherlands! And finally our Chinese counterpart (the Chinese Academy of Scienses , CAS ) paid for al our accommodations, food etc. during this campaign. WOW....
So I observed my second meteor storm with a ZHR of 3600. Highest counts of the meteor storm was about 40-45 Leonids a minute with a radiant elevantion of 20-30 degrees. Because this outburst was caused by various dustrails left by comet 55P/Tempel-Tuttle in 1633, 1666, 1699 and 1866, we saw a broad outburst that lasted longer than the 1999 outburst (caused by one dusttrail of comet 55P/Tempel-Tuttle left in 1899). Because of that I couted 4109 meteors that night. A record for me.
It was the perfect meteor show: the numbers of the 1999 outburst and the the brightness of the 1998 outburst. In total I observed 167 Leonids of -3 or brighter up to magnitude -10.
