On 22 June 2019, around 21:26 UT (17:26 local time), a roughly 5-metre object entered the atmosphere over the Caribbean Sea, and exploded at an altitude of about 25 km over the sea surface, releasing an energy roughly equivalent to 3 kt of TNT. The explosion was first detected by the Geostationary Lightning Mapper (GLM) instrument on board the GOES-16 geostationary satellite.

May will likely be the last month before summer with an average rate of NEO discoveries. Starting in June, most surveys in the South-West of the United States will likely temporarily decrease their productivity due to the summer monsoon season.

The first edition of the Planetary Defense Conference (PDC) managed by the International Academy of Astronautics happened exactly 10 years ago,in the week of 27-30 April 2009 (before the IAA became involved, there were two other PDCs, both in the USA). The conference was held in Granada, Spain, and was the first of a biennial IAA series that is continuing this month, with the 6th conference being held in College Park, USA.

On 1 February 2019 a bright daytime fireball was seen by multiple eyewitnesses around the area of Gulf of Mexico. It exploded over the western tip of Cuba, producing a significant shockwave felt by local residents, and the fall of a large number of stony meteorites, mostly near the village of Viflales.

This year on 8 February marks the 50th anniversary of the fall of the Allende meteorite, the largest carbonaceous chondrite ever found. The atmospheric entry and impact happened at night local time, and were therefore well observed over the entire Northern Mexico. About 2 tonnes of fragments were later collected on ground in a strewn field of about 50 km size.

For the first time since 2012 the year that just ended did not break all records of annual NEO discoveries. This was mostly due to unusually poor weather in Hawaii, where many current NEO discovery surveys are located.

Ten years ago, on 6 October 2008,Richard Kowalski, an observer of the Catalina Sky Survey, spotted the first-ever asteroid found on an imminent collision course with the Earth. Over the following hours, hundreds of astrometric observations, plus light curves and spectroscopic data, were collected by observers all over the world.
