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.</div><div style="text-align: justify;"> </div><div style="text-align: justify;">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.</div><div style="text-align: justify;"> </div><div style="text-align: justify;">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.</div><div style="text-align: justify;"> </div><div style="text-align: justify;">John R.

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 <a href="http://itelescope.net/">itelescope.net's</a> T30 in itelescope.net</div>

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." 2020 NK1 just need more observations.<br />

Credits
The Observations of 2008 TC3 was obtained from the
The Minor Planet Center (MPC)

The data was examine with
Find_Orb Orbit determination software - Project Pluto

The Close-Approach of 2018 VP1 is only about four months away, and an internet search will reveal several clickbait stories. Many times it appears that tabloid writers pick a random asteroid and writes a "story" about it. At times one must have some background or do some research to see what the more accurate story is.</span></span></div>

In other words, it would be safe to assume objects the size of 2018 VP1 has impacted Earth's atmosphere since 2018-Nov-03, the date of discovery. The Earth Impact Effects Program also suggests that the fireball is unlikely to do any significant damage. NASA JPL list kinetic energy at impact from 2018 VP1[IF ANY] as ~ 0.00042 MegaTons of TNT. The Chelyabinsk event was 0.4 to 0.5 MegaTons of TNT.</span></span></div>

It's only a few meters across but JPL's SENTRY has it at 1 chance in 240 of impacting on Nov 2, 2020 (ESA/NEODys has it at 1 in 400). Path of risk stretches across the Pacific.
