EN-98 Fireballs Posted on Mon, November 23, 2015 18:41:27

After ending the visual observations I noticed a bright flash that lit up the ground and surroundings. It was a Northern Taurid fireball with a terminal flash of at least magnitude -7.

Dusttrail of Comet 55P/Tempel-Tuttle

Meteors Posted on Mon, November 23, 2015 17:19:17

During the night of 22/23 november 2014 I could observe
a couple of hours from the Groevenbeekse Heide. This to see if the dusttrail of
Comet 55P/Tempel-Tuttle from the year 636 shows some activity in the form of
Leonid meteors. I counted some Leonids from 1 to 4 an hour. All Leonids were
weak, but one was a beautiful magn. -2. In total I counted 48 meteors, amongst
them 11 Leonids, 3 alpha Monocerotids and 3 Northern Taurids.
I took with me to the heath a
Canon EOS6D equipped with a
Canon EF 8-15 mm F4.0 USM lens ye fish. The camera captured 4 meteors, including two
Leonids of magnitude -2 and -4. It was also captured
with my all sky
camera EN-98. This is a Canon EOS 40D with a
Sigma 4.5 circular
fish eye lens and a rotating shutter. And
last but not least also my CAMS camera 352 captured this Leonid. Here are some
pictures of this night.
