Another Fireball captured by Portuguese Meteor Network Cameras

Picture 1 Another fireball crossed last night 21 to 22th February the sky over Portugal. It was registered by TEMPLAR4 and RO2 systems from Portuguese Meteor Network (pictures 1 and 2). Picture 2 We were able to compose two MPEG videos from individual BMP frames from each camera (videos 1 and 2). http://meteornews.org/wp-content/uploads/2017/02/T4.mp4 Video 1 http://meteornews.org/wp-content/uploads/2017/02/SPO20170221.mp4 Video 2 Rui Gonçalves calculated its initial velocity as being 58400 m/s, beginning at 117,1 km high and ending at 76,4 km (pictures 3 and 4). Picture 3 Picture 4 With a negligible mass its magnitude was estimated to be -2,7 according to...

Two slow meteors with spectra

Authors: Martin Dubs, Stefano Sposetti, Roger Spinner and Beat Booz On January 2, 2017 two peculiar meteors (M20170102_001216 and M20170102_015202) were observed by several stations in Switzerland. Both had a long duration, slow velocity, similar brightness and a very similar radiant. As they appeared in a time interval of 100 minutes, a satellite was suspected as a possible origin of these two observations. A closer inspection however showed that this interpretation was incorrect. The two objects were slow meteors.  Spectra were taken from both objects, which were nearly identical. Together this points to a common origin of the two...

Meteor Activity Outlook for 18-24 February 2017

During this period the moon starts out just slightly less than half illuminated and wanes down to a thin sliver, rising just before the sun. This weekend the moon rises near 0100 as seen from mid-northern latitudes. It’s nearly half illuminated and still bright but it does not possess the overpowering effect on faint objects that the full moon does. One can hold successful meteor viewing sessions this week by simply facing away from the moon toward darker portions of the sky. You can also view before the moon rises but February evenings are dreadfully slow as seen from the northern hemisphere.
