Lunar Impact Candidates recorded
5° Lunar Impact Candidate recorded by SNdR Luna UAI
A new important flash of an impact 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. Dalle primissime analisi che ho effettuato direttamente sul filmato in file AVI fornitomi dal membro di Sezione Bruno Cantarella, dopo aver convertito con il programma VirtualDub i frames della sequenza del flash in file BMP ho potuto verificare con il programma IRIS che il flash è visibile in 29 frames consecutivi, ed il tempo di durata del flash calcolato sempre con VirtualDub è stato di 1,12 secondi (11,2 decimi di secondo) quindi di circa 11 volte superiore al tempo medio della durata di un classico flash da Impatto che è di circa 1 decimo di secondo.
Di seguito sono pubblicate le due immagini del flash al picco di luminosità riprese dai due strumenti impiegati per le osservazioni, e per il tempo esatto di riferimento è quello segnato dal timestamp sull’immagine ripresa dal telescopio Newton 100/400 ed è espresso in TU.

Di seguito è invece pubblicata l’animazione in formato gif del flash da Impatto ripreso dal telescopio Newton 200/1000 ad f/2,9 e la sequenza è stata composta con 23 frame ed il tempo di inizio del primo frame della sequenza è 20:56:10:093 (N.B. qui il tempo del timestamp è espresso in Ora Estiva).

E' stata poi ricavata la posizione selenografica del flash da Impatto e le coordinate selenografiche ottenute sono alla Latitudine 8,0° Nord e Longitudine 76,5° Ovest, +/-1° su entrambe le coordinate selenografiche, e la zona lunare dell’impatto è stata individuata ad Est del cratere Glushko, a circa 20 km di distanza dal bordo Est del cratere.
Come per i precedenti Candidati Impatti già registrati dagli stessi membri della Sezione è stato effettuato il consueto invio dei dati osservativi al Marshall Space Flight Center della NASA che si occupa a livello professionale per la raccolta dei dati sugli Impatti Lunari dove il Team dei ricercatori statunitensi ha valutato in modo molto positivo il risultato ottenuto, e quindi i risultati saranno pubblicati sul rispettivo sito web dello stesso Centro NASA competente in materia.
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.

3° Lunar Impact Candidate recorded by SdR Luna UAI
On 2016 November 6 at 17h 43m 12s UT the members of SdR Luna UAI Bruno Cantarella and Luigi Zanatta (Melazzo, AL, Italy, 44°39'25" North, 8°25'52" East) have recorded the third flash of meteoroid impact on the lunar surface. The observation and record of this impact flash has been made with one telecope Newton 200/1000 f/2.9 with astronomical videocamera ZWO mod. ASI 120MM at frame rate of 25 fps and image resolution of 640x480 binning 2x2. The telescope at the moment of observation was installed on equatorial mount EQ6 Skywatcher. At this moment the Impact Candidate it is not confirm by others independent observers. 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 first and second 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° 30 in the list of Independent Observers of NASA Meteoroid Environment Office . The phenomenon is last about 0.08 seconds (1/12 sec.) and the impact zone has been located at the selenographic coordinates 74.5° Ovest and 2.2° North +/-0.5° in the lunar zone to North of Grimaldi, and more precisely at South of Hedin F crater and to North-North-East of Riccioli H crater.
