At the 31.7.2016 the minorplanet 24-Themis has occulted a 12 mag star.
Before the event I´ve checked the target field via Palomar Sky
Survey at http://archive.eso.org/dss/dss.
On the POSS-1 picture is a little comet visible.
The comet is at the position RE 21:55:20 DE -13:53:30.
The plate was selected via the POSS-Plate-Finder at
The picture was made at 29.June.1982 17:53 UT at the Anglo Australien
It´s part of the SERC-J Survey.
The exposuretime was 60min. The comet was slowly!
With the JPL Small Bodies Data Browsers are all comets calculated which
are visible at that time. Nothing fits to the position.
Similar is the situation with http://ssd.jpl.nasa.gov/horizons.cgi. The
MPChecker shows only a minor planet nearby. It´s (4270)
The position of Juanvictoria don´t fit to the position of the
To check the comet I´ve fitted the comet with the right
orientation relative to the stars into a skychart of the australian
At 29.June.1982 17:53 UT the sun and the moon were more than 18 degree
below the horizon. The area of the comet was 70 degree above the
The comet was near the ecliptic and has 140 degree distance from the
sun. So the gas-trail is very short. Length and position of the
gas-trail fits to the position of the sun. The longer and better
visible trail is the dust-trail.
The comet looks real!!
- Maybe it´s undiscovered. 1982 is 34 years ago. At that time
there were no much observers active on the southern hemisphere.
