Profile of (216) Kleopatra in progress

Donnerstag, März 19th, 2015

10:05 UT

A list of all positive and negative observations and the profile is available at Eric Frappa’s euraster.net:

http://www.euraster.net/results/2015/index.html#0312-216

 

From „Occult Watcher“:

Nine stations reported a „Clouded out“ and therefore are not included at the list of euraster.net.

Five stations had technical problems. Unfortunately all of these stations were inside the real path.

 

Many thanks to all observers who joined the team for observing this great event!
