                                                                            5° Lunar Impact Candidate recorded by SNdR Luna UAI

A new important flash of an impact of one meteoroid on the lunar surface has been observed and recorded on 2017 September 27 at 18h 56m 12s UT by the members of Sezione Nazionale di Ricerca Luna UAI Bruno Cantarella and Luigi Zanatta from the observative site of Melazzo, AL, Italy, 44°39'25" North, 8°25'52" East. The observation and record of the impact flash has been made at the same time by two differents telescopes, the first a Newton telescope 200/1000 with a focal reducer at f/2.9 with astronomical videocamera ZWO mod. ASI 120MM at image resolution of 640x480 with binning 2x2 at frame rate of 25 fps, and the second a Newton telescope 100/400 at f/4 with an other identical astronomical videocamera ZWO mod. ASI 120MM at image resolution of 512x384 with binning 2x2 at frame rate of 30 fps. At the moment of observation and record of impact flash both the telescopes was installed in parallel mode on one equatorial mount EQ6 Skywatcher. From the first analysis made by Antonio Mercatali Responsible of SNdR Luna UAI and Coordinator of Lunar Impact Project, has been checked that the impact flash is visible in 29 consecutive frames, and the duration time of flash has been of 1,12 seconds (11,2 tenths of second) therefore with a time about 11 time upper of the medium duration of a classic impact flash that is about 1 tenth of second.
Under are published the two images of flash at the luminosity peak taken by two telescopes, and for the exact time UT of impact flash it is written in the timestamp on the image taken with telescope Newton 100/400.

                                                                            4° Lunar Impact Candidate recorded by SdR Luna UAI

A new flash of an impact meteoroid on the lunar surface has been observed and recorded on 2017 January 1 at 17h 47m 07s UT by the members of SdR Luna UAI Bruno Cantarella and Luigi Zanatta from the observative site of Melazzo, AL, Italy, 44°39'25" North, 8°25'52" East. The observation and record of the impact bright phenomenon has been made by a unique Newton telescope 200/1000 with a focal reducer at f/2.9 with astronomical videocamera ZWO mod. ASI 120MM at frame rate of 25 fps, with image resolution of 640x480 binning 2x2. The telescope at the moment of observation was installed on equatorial mount EQ6 Skywatcher. Also the same flash Impact has been observed and recorded and therefore confirmed by the Dott. Tony Cook of the BAA. After the send of the observativies date by the Lunar Impact Project Coordinator of SdR Luna to NASA Marshall Space Flight Center, as in the case of the previous Impact Candidate recorded by the same members of our Lunar Section, the Team of American researchers has valued in positive mode the result obtain and has classified the new flash as Lunar Impact Candidate n° 31 in the list of Independent Observers of NASA Meteoroid Environment Office . From the analysis made always by the Lunar Impact Project Coordinator of SdR Luna, the duration of the phenomenon has been about 0.04 seconds (0.4 tenths of second), and the impact zone has been located at the selenographic coordinates of 18.2° West and 21.6° South +/-0.5° in the lunar zone at North-North-East of Wolf A crater, and at South of Gould B crater. The image visible below show the impact flash sequence indicate by two red lines.
