ALCon 2023 Presentation

The 2023 Astronomical League Convention will be held in Baton Rouge, Louisiana from July 26th to 29th. Our theme will be “Astronomical Gumbo," which represents the blend of diverse subfields and people within the vast field of astronomy. Gumbo is a dish that combines the culinary practices of Africans, Native Americans, French, and Spanish, and is often used as a metaphor for the mix of cultures that exist in southern Louisiana. Baton Rouge, which is French for "red stick," is the capital of Louisiana and sits along the mighty Mississippi River. The city's many attractions include a planetarium, the new and old State Capitol buildings, and many museums. Serving as the melting pot between the urban cityscape and the rural scenes of nature, Baton Rouge is home to plenty of art, music, and great food for visitors and families to enjoy.

 

Baton Rouge Astronomical Society, or BRAS, was established in 1981. With over 100 members, it is Baton Rouge's premier meeting place for amateur astronomers. BRAS features a diverse collection of individuals, ranging from new members seeking to learn the basics to more experienced observers sharing their knowledge with others. Anyone who shares the common love of astronomy is welcome to join.

 

Louisiana is home to LIGO Livingston, one of only 5 gravitational wave interferometers in the world, and one if only 2 in the United States. Visitors are able to tour a world-class scientific research facility located deep in the of the pine forests of Livingston.

Back of the Envelope Calculation Using the JPL's Fireball Data --- 2018 VP1

 I did a back of the envelope calculation using the JPL's fireball data to estimated that asteroids equal to or greater than 2018 VP1 impact the Earth at a rate of one every 37 to 53 days. IMHO we are at greater risk from the "background." https://docs.google.com/spreadsheets/d/12i7lhXgL0u6m36eoenKDKV-dLtkoedz0/edit?f#gid=1305411600 asteroid https://cneos.jpl.nasa.gov/fireballs/ https://cneos.jpl.nasa.gov/sentry/details.html#?des=2018%20VP1

The NEO 2020 NK1 On 2020-07-21 From Siding Spring Observatory Australia.

The NEO 2020 NK1 Has Been Rated Torino Impact Hazard Scale 1 this happens a few times a year. The current The NEO 2020 NK1 Has Been Rated Torino Impact Hazard Scale 1 this happens a few times a year. The current Torino Scale state for 1 " A routine discovery in which a pass near Earth is predicted, that poses no unusual level of danger. Current calculations show the chance of collision is extremely unlikely with no cause for public attention or public concern. New telescopic observations very likely will lead to reassignment to Level 0."  I in order to help lower uncertainty I did an imaging run with itelescope.net's T30 in itelescope.net
