Last night was a busy night for the AMS: 2 very bright fireball events occurred less than 6 hours apart.<\/p>\n

Fireball over Germany: 45 reports from 4 countries<\/h3>\n

AMS first received\u00a045 reports<\/strong><\/a>\u00a0(so far) about of a slow green\u00a0fireball<\/a>\u00a0seen above north Germany on Tuesday, April 16th<\/sup>\u00a02019 around 21:50 Universal Time (23:50 local time \u2013 CEST). The event was mainly seen from Germany but reports also are sent from Sweden, Denmark and the Netherlands.<\/p>\n

AMS Event #1774-2019<\/a> \u2013 Witness location and estimated ground trajectory<\/p><\/div>\n

Trajectory<\/h4>\n

The preliminary 3D trajectory computed based on all the reports submitted to the AMS* shows that the fireball was traveling from South East to North West and ended its flight right above Hamburg.<\/p>\n

* through AMS partners:\u00a0Arbeitskreis Meteore e.V.<\/a>\u00a0(D), the\u00a0International Meteor Organization<\/a>,\u00a0Werkgroep Meteoren<\/a>(NL),\u00a0Vallendesterren<\/a>\u00a0(NL) and\u00a0UKMON<\/a>\u00a0(UK).<\/p>\n

Video<\/h4>\n

AMS AllSky6 Camera operators Andr\u00e9 Kn\u00f6fel from Lindenberg, Germany and Sirko Molau from Seysdorf, Germany caught the event on this cam (see\u00a0video<\/a>\u00a0below). It is the only media sent to AMS about this event so far.<\/p>\n

Fireball over Delaware: 325 reports from 12 states<\/h3>\n

AMS also received\u00a0325 reports<\/strong><\/a>\u00a0so far about another bright and green fireball that happened over Delaware the same night at 02:57 Universal Time (10:57pm EDT). Reports was sent from Washington DC, Delaware, Massachusetts, Maryland, North Carolina, New Hampshire, New Jersey, Pennsylvania, South Carolina, Virginia, Vermont and West Virginia.<\/p>\n

\"AMS<\/a>

AMS Event #1775-2019<\/a> \u2013 Witness location and estimated ground trajectory<\/p><\/div>\n

Trajectory<\/h4>\n

The preliminary 3D trajectory computed based on all the reports submitted to the AMS shows that the fireball was traveling from North to South and ended its flight in the Atlantic Ocean in front of Bethany Beach, DE. It means that if anything survived, it\u2019s in the water.<\/p>\n

Video<\/h4>\n

Both AMS AllSky6 Camera operators Elizabeth Warner (MD) and Ed Abel Mathias (WV) caught the event:<\/p>\n

Fireball, Meteorite\u2026?<\/h3>\n

Several thousand meteors of fireball magnitude occur in the Earth\u2019s atmosphere each day. The vast majority of these, however, occur over the oceans and uninhabited regions, and a good many are masked by daylight. Those that occur at night also stand little chance of being detected due to the relatively low numbers of persons out to notice them.<\/p>\n

Additionally, the brighter the fireball, the more rare is the event. As a general thumb rule, there are only about 1\/3 as many fireballs present for each successively brighter magnitude class, following an exponential decrease. Experienced observers can expect to see only about 1 fireball of magnitude -6 or better for every 200 hours of meteor observing, while a fireball of magnitude -4 can be expected about once every 20 hours or so.<\/p>\n
