Meteor Activity Outlook for 28 January-3 February 2017

During this period the moon reaches its new phase on Saturday January 28th. At this time the moon will be invisible in the night sky and will not hinder meteor observers at all. Later the in the period the waxing crescent moon will enter the evening sky but will set long before the more active morning hours arrive.

Long and fast trail grazing meteor over Spain Portugal

Fireball atmospheric trajectory over southern Spain and Portugal   A long and fast trail grazing meteor with an absolute magnitude estimated of -2, was captured on 20th January under clear sky condition by three PMN (Portuguese Meteor Network) systems; TEMPLAR5, TEMPLAR2 and TEMPLAR4. TEMPLAR5 summed image (IPT-Tomar). TEMPLAR2 summed image (Linhaceira-Tomar). TEMPLAR4 summed image (Linhaceira-Tomar). The meteor started at East (Templar5 at 00:03:32-35), crossed from left to right Templar2’s entire field at south (00:03:34-37) and ended at southwest at Templar4’s field (00:03:37). Rui Gonçalves has calculated the trajectory, but unfortunately the meteor had traveled through PMN gaps, and only his systems caught this event. Systems from south Spain were under clouds. The baseline between Templar5 and Templar2&4 are only 9 km apart. Nevertheless, the trajectory seems correct (with interception plane’s angle of 1.8°) and 0.0° horizontal angle. UFOrbiter gives roughly the same result. The meteor was detected from 106.6 km to 113.0 km with an initial velocity of about 66.0 km/s. The velocity remains almost constant with small increase ?!. Estimated photometric mass is very small (about 1 g). Ground projection from UFOrbit software. At start, altitude is decreasing (for just 0,32 s) then altitude increases until the meteor vanished after a flight of about 300 km in the course of 4,6 s. The light curve values decreases also as the meteor interacts less and lesser with the thin upper...

Fireball over Denmark 20 January 2017

A bright slow moving fireball was captured above Denmark at 06h12m50s UT. It started at 78 km and ended at 50 km elevation with an entrance angle of 14°. The velocity was 19 km/s and the radiant was sporadic with R.A. at 132.3° and decl. +5.1°. The featured photo was registered at Hobro, Denmark (see top). The orbit was of an asteroid type with: q= 0.545 AU e = 0.467 i = 6.8° ω = 113.6° Ω = 120.2 The video can be from both camera stations can be viewed from: http://stjerneskud.info/fb/event2017-01-20-07-12-50/klh.avi http://stjerneskud.info/fb/event2017-01-20-07-12-50/hob.avi...

Meteor Activity Outlook for 21-27 January 2017

During this period the moon wanes from slightly less than half illuminated to nearly new, when it will be to thin and too close to the sun to see. This weekend the waning crescent moon will rise during the early morning hours and will interfere with viewing meteors if you look in its direction. If you face away from the moon once it clears the horizon the moonlight will hardly be noticeable.
