A tiny world beyond Neptune has an atmosphere that shouldn't exist
A team of professional and amateur Japanese astronomers have found evidence for a thin atmosphere around a small body in the outer solar system. The object is so small that it should not have a sustainable atmosphere, raising questions about when and how the atmosphere formed. Future observations to better characterize the atmosphere will help solve these mysteries.

57 observing stations are announced on Occult Watcher Cloud.
Fingers crossed for a few breaks in the clouds. ⭐ ☁️ 🔭

A portrait about (136108) Haumea was published in Journal for Occultation Astronomy 2019-03, page 22-25.
A special zoomable map for this event is available here:

It shows the path limits as well as the limits for the ring.
Special Call for Observations:
Trans-Neptunian object (136108) Haumea occults UCAC4 524-056397 (Vmag 14.7) on 2026 May 04.
Haumea has two moons and a ring!
An occultation by the ring can be observed from central Europe. Be aware: this is a very challenging observation.
52 stations have already announced their observation attempts on Occult Wachter Cloud:

An expedition by IOTA/ES has successfully observed a stellar occultation by asteroid (65803) Didymos at Pabillonis, Sardinia, on 2026 April 16.
An occultation with a duration of 0.3 s was recorded with IOTA/ES' portable 50-cm-telescope M2.
Good work, guys! 👍
(65803) Didymos and its satellite Dimorphos were targets for NASA's DART mission. ESA's mission HERA is now on its way to reach the asteroid in November 2026.

MEETINGS - Trans-Tasman Occultation Alliance
TTOA have run annual meetings – The Trans-Tasman Symposia on Occultations (TTSO) – since 2006. These are open to members and visitors on a range of occultation topics including training and information sessions. Apart from the ‘COVID’ years, these have been physical in-person meetings with online streaming/sharing increasingly engaging involvement with international participants. Pages on […]
