Lyrid Meteor Shower Project - ISS was created by michaeloconnell
Tolis in Armagh Observatory was in contact with regard to a project involving the Lyrid meteor shower and the ISS.

Tolis states:

Don Petit (who is currently at the ISS and an amateur astronomer) will be using his digital camera to take pictures of Earth's nightside atmosphere to detect meteor streaks from orbit during the night of the Lyrid meteor shower peak (21-22 April). At the same time a ground-based campaign will be going on to attempt to observe the same meteors from the ground and triangulate the orbits.

As far as observers from Ireland are concerned, I woud advise anyone with a video/ CCD camera or just the Mk1 Mod 0 eyeball to go out and observe. The best direction to observe given the ground track of the ISS at the time (mid-Atlantic) is probably due SW. If you have a small FOV (30-40 deg or less) camera my suggestion would be to point it as close to the horizon as possible (unless strongly castrated by light pollution in your area) in order to cover a large atmospheric volume. For wide filed/viual searches a search in the broad SW sky while keeping
an eye to the horizon is advisable.

If you would like to participate (and the weather proves favourable) the one thing that we would absolutely need from you is the time of the meteor so that we are able to identify a match among Don's meteor detections. High timing accuracy is not necessary but you need to know the time of your observation to the nearest 10 seconds.
At the end of your observing session please submit:
(a) your geographic location lon/lat
(b) the region of sky covered (high/low, which quadrant or, even better, elevation/azimuth or constellations)
(c) the times of the meteors you detected in UT (subtract one hour from BST to get that) and your own personal estimate of the uncertainty in those time estimate.


If you would like to participate, please post your results here.
I will then co-ordinate with Tolis on behalf of members here.

If you have any queries, please do not hesitate to ask.
