New Occultation by 2010 EK139 on 20-21/March

[Felipe Braga Ribas]

Dear colleagues,

we will have another good opportunity to observe an occultation by the
large TNO 2010 EK139. The event will occur on the night of the 20 to
21st of March, crossing South America. The uncertainty is large, so if
you have easy access to telescopes, please observe.

The star is fairly bright R=14.5, and the event can last for almost 25 seconds.

The latest map can be found on my web page and a link to more
information is available.

Kind regards,
