Meteor Activity Outlook for 2-8 December 2017

During this period the moon will reach its full phase on Sunday December 3rd. At that time the moon will lie opposite the sun and will lie above the horizon all night long as seen from the northern hemisphere. Later in this period the moon will rise during the late evening hours allowing a few hours of observing under dark skies between dusk and moon rise.

Leonids 2017 from Norway – A bright surprise!

Introduction After missing the maximum nights of the Orionids due to bad weather, I hoped for better luck in the maximum night of the Leonids. November weather is generally very bad in Norway, but the weather forecast gave hope for a clearing in the morning hours on November 17. The IMO calendar had indicated two possible maximum times, in the early afternoon hours of November 16 and 17 respectively, both with ZHR around 10. Being hours away from these timings, my best hopes was hourly rates between 5 and 10 meteors. These expectations were met, but the Leonids were...

Meteorite fall on Nov. 16

This meteor event was recorded over the Atlantic Ocean on Nov. 16 at 0:06 universal time. The event was produced by a fragment from an asteroid that hit the atmosphere at about 54000 km/h. The fireball began at an altitude of around 90 km over the sea, and ended at a height of about 27 km. The analysis of its atmospheric path shows that this was a meteorite-producing event. The meteorite would have fallen into the sea. The event was recorded by the meteor observing stations operated by the SMART Project (University of Huelva) from Sevilla and...

Stunning Leonid meteor over Spain on Nov. 18

On Nov. 18, at 4:35 local time (3:35 universal time) a very bright (mag. -8) Leonid meteor was spotted over Spain. It was produced by a fragment from Comet Temple-Tuttle that hit the atmosphere at about 260.000 km/h. The event begun at an altitude of around 133 km over the province of Jaen and ended at a height of about 83 km over the province of Cordoba. It was recorded in the framework of the SMART Project (University of Huelva) from the astronomical observatories of La Hita (Toledo), Calar Alto (Almería), La Sagra (Granada), Huelva and Sevilla. This video shows this event as spotted from La Hita Astronomical Observatory...
