I am working on getting a website The Asteroid News up and running

 I am working on getting a website the Asteroid News up and running. There is a need for very high quality researches, writers, editors, web editors, coders, databases, etc. info(AT)theasteroidnews(dot)com

The Asteroid 2020 NK1 Has Been Removed From Sentry: Earth Impact Monitoring

What is Up With Asteroid 2018 SV13

Here a write up "What is Up With Asteroid 2018 SV13" Is asteroid 2018 SV13 real? NO

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

The NEO 2020 NK1 Has Been Rated Torino Impact Hazard Scale 1 -- Normal (Green Zone)

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."  2020 NK1 just need more observations.

2018 SV13... "the object is not real"

There has been some media hub ba over 2018 SV13 Update on 2020 July 17 at 14:31 UT the Minor Planet Center Issued "MPEC 2020-O10 : RETRACTION OF 2018 SV13" .. 2018 SV13 " … the object is not real..." see https://minorplanetcenter.net/mpec/K20/K20O10.html

Using Find_orb and Guide9 To find the impact location of The NEO 2008 TC3. Credits The Observations of 2008 TC3 was obtained from the The Minor Planet Center (MPC) https://www.minorplanetcenter.net/db_search/show_object?utf8=%E2%9C%93&object_id=2008+TC3 The data was examine with Find_Orb Orbit determination software - Project Pluto http://www.projectpluto.com/find_orb.htm Text editing done with MS Notepad The impact.tdf graphic was done with MS Paint.
