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.

Meteor Activity Outlook for 11-17 February 2017

During this period the moon reaches its full phase on Saturday, February 11. This weekend the bright moon will make meteor observing extremely difficult as all but the brighter meteors will be obscured by the lunar glare. Toward the end of the period there will be several hours of dark skies available between the end of dusk and moonrise during the evening hours.

Radio Meteor Observations in the World: Monthly Report in January 2017

Radio Meteor Observations in the World: Monthly Report for January 2017 by The International Project for Radio Meteor Observation. Quadrantids 2017 One of the major meteor showers, the Quadrantids occurred in this month. The activity level was the same as other years, although it was weaker than in 2016. The maximum activity level was 4.0 at around 15:30(UT) on January 3rd (solar longitude 282°.2). Its FWHM was -9.0hours  / +5.0hours. You can see the detailed information on the page “Result for the Quadrantids 2017“. In addition, Mr.Hirofumi Sugimoto converted from the Activity Level index to the visual ZHR.
