EN-98 Fireballs Posted on Sun, April 17, 2016 11:54:30

A very bright fireball with a possible meteorite impact appeared above Belgium on April 25, 23:00:45 UT and was also captured with myy all sky camera. Unfortunately, only the first 50-60% was captured before it disappeared behind the trees….

2016-03-17 03:16:55 UT: St Patricks Fireball

EN-98 Fireballs Posted on Sun, April 17, 2016 11:43:29

On March 17, 03:16:55 UT a very bright and spectaculair fireball appeared above the United Kingdom. A full report with many video recording: http://meteornews.org/st-patricks-day-fireball-united-kingdom/

After a close inspection of the images my all sky camera took that night I found this fireball. It was visible throught the branches of the trees low in the west. Not as spectaculair as the video recording, but it was captured with my all sky camera. Distance about 500 km!

EN-98 Fireballs Posted on Sun, January 17, 2016 15:12:24

In the morning of Januari 9, 2016 I was observing meteors between 00:05 and 03:05 UT. I logged 37 meteors, amongst them 3 late Quadrantids, 3 Antihelion meteors and 2 delta Leo Minorids. The brightest meteor was a magnitude -3 delta Leo Minorid. It was also captured with my all sky camera.

Four fireballs originating from the same location on the sky?

EN-98 Fireballs Posted on Sat, December 12, 2015 12:55:02

On December 8 (02:46:02 UT), December 9 (02:39:22 UT), December 11 (22:06:38 UT) and December 12 (03:25:41 UT) my all sky captured four fireballs. They seems the originate from one location at the sky. I made a composition of the three brightest fireballs. see picture below.

Picture 1. Composition made of three fireballs captured on December 8 (02:46:02 UT), December 9 (02:39:22 UT), December 11 (22:06:38 UT) and December 12 (03:25:41 UT). Click on the image for a better resolution.

The three fireballs are visible as tracks which are interrupted by the rotating sector. It therefore seems that the fireballs appear to originate from the same region of the sky (so called radiant). You can see this by extending the tracks backwards. The backward extended meteor tracks intersect in an area of the sky where the radiant of the December Monocerotids lies. So it is possible that these fireballs ar December Monocorotids!

Picture 2. Crop of previous image and the radiant of the December Monocerotids. Click on the image for a better resolution.

Several CAMS stations have also recorded these fireballs and the simultaneous calculations can hopefully then give a definitive answer about the origin of these fireballs.
