On August 1, 2013 at 02:21:55.7 UT, a small meteoroid has impacted the Moon's surface. The kinetic energy transformed by the impact into thermal energy also caused a short and intense flash of light that was detected by telescopes of R. Lena, A. Manna and S. Sposetti.

The simultaneity of the flash and the same position on the lunar surface indicates it is an impact. The event described above has been observed by Raffaello Lena (GLR group, Rome Italy) with a refractor 130 mm and with a video camera Mintron. Andrea Manna observes from Cugnasco (Switzerlnd) and this morning decided to with a Schmidt Cassegrain 200 mm and a camera watec 120N+. Stefano Sposetti (Gnosca, Switzerland) detected the flash using two telescopes: Refractor 150 mm and SC C11” equipped with watec 902H2 cameras.The two observatories in Switzerland are at a distance of 10.0 km. The observatory in Italy (Rome) is at a distance of 558 km from Gnosca. Time synchronicity of the various files is assured by using a GPS time inserters (KIWI-OSD) and an Atomic Clock Synchronization protocol.

The meteoroidal lunar impact detected on August, 1, 2013 at 02:21:55.7 UT was simultaneously from four independent video recordings. The duration of the flash correspond to 0.08s and reached a peak brightness of 8.3 ± 0.7 mag. The selenographic coordinates of the lunar impact flash are determined to 73° ± 4° E and 27° ± 3° N, near the crater Seneca C. The examined impact flash probably corresponds to a α-Capricornids shower exhibiting favourable impact geometry on the impact date.

Enclosed an image of the detected lunar impact. A report of the observing session is published in Selenology Today 33 http://digilander.libero.it/glrgroup/

Thanks at all.
I am proud of this study, carried out with a team of 3 observers. As for my detection i used a TMB 13 cm as telescope ! well Jim:)
The distance between Rome and Gnosca (Switzerland) is very long really => 558 kms. This is an aspect of relevance for a genuine detection!

Congratulations on this Raf. It is amazing to me that this object is still under bombardment but such is the life of a body without an atmosphere. Thanks for posting!!!

We will try a future observing run during the perseids
