2016-02-28 22:24:44 UT: bright sporadic meteor

CAMS BeneluxPosted by Koen Miskotte Mon, February 29, 2016 11:24:49

In the afternoon of Februari 28, 2016 it seemed that middle NL would be conquered by a thick layer of cirrus moving in from the southsoutheast. But in the evening the cirrus comes to a standstill over Ermelo. I wanted to observe from the Groevenbeekse heath, but decided to stay at home so that I can observe to the north. However, around 20 UT I noticed that the remaining cirrus was dissolving quickly. So I took of to the heath. Once there, there is still some cirrus in southeasterly direction, but it was very thin.
I started the session at 21:22 and at 21:24:44 UT I observed the best meteor of this session and year! A very nice and slow magnitide -2 sporadic meteor moved from below Castor and Pollux through Cancer and then to the sickle of Leo. Duration 2 to 3 seconds. Very beautiful with a yellowish color and a short wake. The meteor showed no flares and extinguished slowly. The finest meteor of this year and the last part of the track was captured with my CAMS 351 camera. That must be simultaneous. The all sky camera also captured the meteor, but marginally. See the combination picture In total I observed during 2h44m effective time 15 meteors of which 4 were Antihelions.

Later that night CAMS 352 recorded a slow and long meteor near the "head" of Draco.

CAMS Benelux results

CAMS BeneluxPosted by Koen Miskotte Mon, October 06, 2014 11:02:00

Today Marco Langbroek published three pictures with results of the CAMS Benelux network (calculations done by Carl Johannink) on his Facebook page. Two of them I placed here. Thank you Marco!

Figure 2: All trajectories of meteors captured with my CAMS stations 351 & 352.
The single trajectory between both aimingsponts is the trejectory of the great fireball of 19 september 2014.

Meteor observatory

CAMS BeneluxPosted by Koen Miskotte Sat, January 25, 2014 16:37:28

On January 25, the roof of my dormer was adapted as a small meteor observatory. There are now two fixed CAMS systems (CAMS 351 and CAMS 352), and a all sky camera (EN-98). |
The all sky camera is still in a preliminary setup, in the future it eventually comes at a higher place so I have no obstruction anymore of a part of the roof and the chimneys.

Around the flat roof I made a lightshield, it is about 30 cm high. It was made of trespa. Trespa is made of very strong wood fibers combined with various resins. It is very strong material and requires no maintenance. Notably the all sky camera suffered from light reflections that ended up in the camera via the sector.

For visual observations I made a place with eight rubber tiles of 40 cm (so it measures 80 x 160 cm) were I can lie down and observe the meteors. There I have a very good view in northern direction, but also in southern direction (although there is some obstruction of the roof to about 20 degrees high).
My regular observing place is at the Groevenbeekse Heide (a heath 500 meters away from my home), but I regularly have problems with strongly varying weather conditions or there is a thick layer of ground fog on the heath. So this is a nice alternative. Maximum Lm on the heath is 6.5, on my flat dormer roof it is about 6.3.

Hoping now on clear nights.....
