Besoek aan Carnarvon meerKAT/SKA

Gaan loer hoe lyk die meerkatte (SKA) by Carnavon. Auke Slotegraaf was saam met `n groep daar.

Gedeeltelike sonverduistering Vrydag, 15 Januarie.

Net so `n katspoegie van `n verduistering. Die enigste vir 2010 hier in die Suide. Op die voorstelling wat met TheSky 6 gemaak is kan mens sien hoe die gedeeltelike verduistering Vrydag om 07:30 gaan lyk. Dit begin om 06:58, bereik sy maksimum om 07:30 en eindig om 07:59. Venus is regs bo in die prentjie.

2010 ASSA Symposium

The Pretoria branch of ASSA is proud to announce the dates for the Southern African Eighth biennial Symposium of the ASSA.  The symposium will take place at the Silverton campus of the Council for Geoscience on Thursday 7 October 2010 and Friday 8 October 2010.  The preliminary program for Saturday includes a morning visit to HartRAU and a guided tour through the Tswaing meteorite impact crater during the afternoon.

The symposium will focus on light/spectrum pollution and people interested in delivering papers are invited to send a short synopsis to Andrie van der Linde at andrie@eridanusoptics.com.  You can also make a preliminary booking if you plan to attend.

Details on registration fees and suggestions for accommodation, etc will be available soon.

Is die seisoen vir Sonvlekke hier? Het die gety gedraai?

Sunspot 1040 is busy growing again. In only 24 hours, it has expanded from a barely visible "sun-speck" to a planet-sized active region with 15 dark cores and a tangled magnetic field. Steve Riegel sends this picture from his backyard observatory in Santa Maria, California.

Meteoor! O, Meteoor!

So ver as Kimberley, Reitz en dan natuurlik verder Noord het mense hierdie vuurbal gesien. `n Muur het self gekraak na die impak op die grond. Iewers by 'n wildplaas. Vir ander het die ding net hier agter die koppie geval.

Gaan loer gerus op Auke Slotegraaf se webtuiste na die videos wat tot nou beskikbaar is. Ook wat die ouens sê wat hierdie ongelooflike gebeurtenis waargeneem het.

Leonid Meteor shower + Komeet 88P/Howell

 Komeet 88P/Howell in Sagittarius

Leonid Meteor shower

Vir die ouens wat snags wakker lê. Laat weet gerus of julle iets gesien het! 

This month is the time to look out for the Leonid Meteor shower. Maximum number of meteors per hour is expected on the 17th to 18th. Conditions are expected to be favourable and particularly dark, since this will be only a few days after new moon. As the name indicates, the radiant of the meteor shower will be located in the constellation of Leo. The radiant is the point in the sky from which all the meteors appear to originate from. Meteors, or more commonly called “shooting stars”, are small particles of space dust and debris that enter our atmosphere at high speeds, and burn up due to heat generated by air friction. For keen and enthusiastic observers, the radiant of the shower will be up above the horizon from about 03:00 to 04:00 in the mornings. (Source: The South African Astronomical Observatory (SAAO)

Stay up late or get up early this morning to catch the Leonids. Each year we pass through the
filaments—both old and new—of Comet Tempel–Tuttle’s debris, and the chances of encountering a
particular stream from any particular year becomes a matter of mathematical estimates. We know
when it passed. . . We know where it passed. . . But will we encounter it and to what extent?

Komeet 88P/Howell

Ek het die komeet Saterdagaand so 20:30 deur die stad se ligbesoedeling in die Weste vanaf Boyden opgespoor. Baie dof, maar sigbaar.  As jy `n kaart wil hê om dit op te spoor kan jy vir my e-pos stuur. Sal vir jou `n pdf-kaart stuur.

Hier is inligting oor die komeet.
On this night 88P/Howell is best visible between 19:55 and 20:17, with the optimum view at 20:15. Look for it in Sagittarius, fairly high in the sky during evening twilight. It is detectable visually in the Orion SkyQuest XT10 Dob. Use the Ultima 42mm for optimum visual detection. It is magnitude 9.3 with a diameter of 5.1'.

In the following 30 days this object is detectable visually from November 17-26, and again from December 3 on, with the best view coming on November 17. During this period it will fade by about 0.8 magnitudes and will remain constant in altitude.

88P/Howell will next reach perihelion in mid April 2015. It also is predicted to reach maximum brightness of magnitude 9 in mid April. The best visibility from Bloemfontein, South Africa near maximum brightness is predicted to be in mid April when it will be approximately magnitude 9. At that time it will be in Aquarius, fairly high in the sky during morning twilight and will be detectable in the Orion SkyQuest XT10 Dob. The previous perihelion was mid October 2009. Note that the magnitude and visibility of a comet can be very unpredictable.
