Preparation for the Venus Transit on 6^th of June

To prepare for the big occultation event this year, the VENUS TRANSIT in the morning of the 6^th of June 2012 (for Europe) various information will be presented here in the following weeks.

At first, you find a picture of the so called Lomonossow ring, recorded with a simple webcam and a 27cm Schmidt-Cassegrain System in the year 2004. The center wavelength of the image was 890nm.

Next Quaoar Event only for Specialists:

Quaoar occults star of magnitude 17m3 on the 27th of May 2012 around 0h 48min UT. Read more on Felipes Website here...

No Observation of (50000) Quaoar Occultation April 17th

Occultation of 3UCAC 064456146 (11m6) by (50000) Quaoar on 2012 April 17 visible from the Atlantic Ocean, Africa, Near East and probably Europe!

None of the many stations worldwide has observed any occultation. Observers were distributed in Reunion, 2 Islands of Cabo Verde, Tenerife, Marocco, southern Spain and other locations. Now its assumed, that the shadow may have passed between Cabo Verde and the Canaries, there has been a gap without observers of about 1350km. Perhaps Quaoar has used this exit.....

Special events:

Quaoar events from Europe

There are 3 good events for (50000) Quaoar observable from Europe or not too far away. These are:

17th February 2012	R-mag 15m1
17th April 2012	R-mag 11m2
27th May 2012	R.mag 17m5

All events are easy to observe, but they are not too high in the sky.

NIX event from Europe

There is an occultation by Pluto's satellite NIX on
21^st of Mar 2012 from northern Europe, very low in the sky. Worth to try....

Double occultation events for Pluto and Charon

These are occultation, where the same star is occulted by Pluto and Charon in the same night. They are very important for the relative astrometry of Pluto and Charon. That puts them on the very preferred list!

In order to simplify the management of actual stationmaps and other time critical information we will use from now a new Blog system. For occultations by minor planets you can look at it here.In general you will find the blog link on the outer right blue section of the IOTA-ES website. Or just go to http://call4obs.iota-es.de
