Confirm sisters report

I am one of the brothers that my sister described in her report as being witness of Jupiter 2 looking ufo.  
I was discussing this siting this evening with another brother who saw it and happened to come across my sisters report when looking for old ufo articles in baltimore.  Just wanted to confirm that as my sister described is exactly what i and brother recall and he believes he can narrow down the year after checking with parents.  I feel it is very similar to what other baltimore report saw.  
I believe our parents called police and would have been one of those 200 calls that evening.  That night was clear and the saucer low and moved soundlessly and slowly.  You could make out the outter diameter outline as perfectly circular.  Not blimp shaped.  It had smaller diameter of a dozen or so lights on underside.  I remember thinking at the time how ironic that a ufo would look exactly like the underside of jupiter two of lost in space but i suppose the tv model is modelled after actual sitings.  This was early 70's suburban area.  No hot air balloon and no testing site for aircraft.  Never saw anything like it since even on tv shows showing debunked cases.
Witness indicates that the date of the sighting is approximate.  PD
