22nd February 2017

A fast moving Near Earth Asteroid that will approach us at a distance of 2.37 Lunar distance tomorrow. This asteroid is estimated to be between 47-150m in size is rotating at a rate of 0.823h per rotation. It is considered as a Super Fast Rotator and most likely to be monolithic .. compare to the regular rubble pile structure most asteroids of such size belong to. However with such low amplitude, could it be binary?

Dear Julian,
It is our pleasure to congratulate you on joining the "club" of those with named asteroids.  The naming will appear on the Minor Planet Circulars issued today, and will be announced along with eight others at the banquet of the Binaries-4 Workshop in Prague this evening, sorry you won't be here to join in the celebration, but be sure that some fine Czech beer will be consumed in your honor.  We attach a text of the nine naming citations that will be read at he banquet.

Best regards from Prague,
Alan Harris and Petr Pravec

The asteroid (20325) HO27 was recently renamed to the author (20325) Julianoey.

This animation was done using images taken on 8th of April 2016 in this year's apparition in which photometric work was done to capture the continuation of the events during the binary transits and eclipses.

News in the Wentworth Courier

The latest observations for both comets and asteroids are explained in more detail at the Blog page maintained by
Paul Camilleri

Observing campaign for comet C/2013A1 (Siding Spring) during close encounter with Mars.


All astrometric observations of comet 209P (2014) has been published at Minor Planet Center.

Astrometry report done as of 31st Decmeber 2014 :
192 CCD photometry observations of novae,  supernovae & variable stars to the AAVSO .
(American Association of Variable Star Observers).

We have also confirmed one Supernova SN 2013cz in Galaxy IC4892
Reference CBET 3547.

There has been 200 Minor Planets measured including 2041 astrometry observations
There were also 790 comet observations on 39 different comets.

Work done by Paul Camilleri (The past winner of Berenice and Arthur Page medal) showing some of the interesting observations that were done at Blue Mountains Observatory.
Data obtained on 13th March 2013:
"I found very faint images of an main belt asteroid 2013 CX71 which was discovered in February with pre-discovery images dating back to early January from the SpaceWatch survey in the USA.
The orbital arc for this one was 32days and with our observational data from March 13th  extended it out to 62days."
Just one of the examples where Paul has expertly retrieved the faintest of asteroids found in the data obtained from BMO asteroid photometry studies.
