On Saturday evening/ Sunday morning the asteroid 426-Hippo will occult a mag. 7 star in Sagittarius.
Predicted time for the east coast - 14:13:55 UT = 12:13:55 am on Sunday 10th. The time uncertainty is +/- 5 seconds, but you should observe +/- 1 minute.
Here is the latest prediction...

Occultation of HIP 90639 by 426-Hippo
At right is a colour-inverted screen clip from SkySafari of Scorpius and Sagittarius for Sunday 10
th August 12:13:55am. Kaus Australis (epsilon Sagittarii) is about 52 degrees altitude.
For the star-hopper, the simple map below shows how to get to HIP 90639. The magnitudes are shown next to each star. Depending on your skies, most of the stars shown on the map should be visible in an 8x50 finderscope or 10x50 binoculars. At less than three degrees, the whole field is easily visible in a finderscope.
A magnitude 7 star near Kaus Australis can be used as a directional reference. The magnitude 7 star HIP 90639 and another magnitude 7 star are both about 1.2 degrees from Kaus Australis. In shorter focal length telescopes, it is possible to see Kaus Australis and HIP 90639 in the same field of view using a lowpower eyepiece.
While waiting, you might like to look at a couple of globular clusters in the area (M69 and NGC 6652). You won’t see them in 10x50 binoculars. They are best seen with a telescope of aperture 6” or larger.

Observation reports are welcome. Just post them here...I need to know,
Observer Name;
Site coordinates; Longitude, Latitude, Altitude and site name
Telescope Details; Type, Aperture
Time Reference; NTP, GPS, VTI, Micky Mouse Watch
Observation Times; Start, Disappearance, reappearance and End
If visual Observation; your reaction time estimate (PE) and if you have or have not subtracted PE from your event times.
