*Watch the Moon "Eclipse" the Seven Sisters

 

(Voorstelling op TheSky6 voorberei)

*Watch the Moon "Eclipse" the Seven Sisters - Sunday Feb 21st*
On 21st Feb at about 8:45pm, South Africa will see some of the Pleiades 
stars disappear behind the Moon .  It's pretty rare, and will best be 
viewed through binoculars.  The Pleiades are also known as the Seven 
Sisters or isiLimela.

Technically this is called an occultation - in fact an eclipse of the 
Sun is technically an occultation (one body passing in front of 
another).  For all occultations, the timing depends on where you are on 
the planet.  A list of times for a selection of South African towns, and 
a map of the Pleiades, is at www.planetarium.co.za

Hoe om met sterrekunde as stokperdjie te begin

In die nuwe Canopus (Kliek hier om uit te vind wat is Canopus) is `n paar wenke wat uit "Sky and Telescope gemelk is, oor hoe om jou sterrekunde stokperdjie van die grond af te kry.

Vertaal uit Canopus:

1. Leer die naghemel met die blote oog te ken.

2. Lees! Lees! Lees! Biblioteek en Internet

3. Dink en beplan om jou erste teleskoop aan te skaf, maar begin met `n verkyker.

4. Kyk na sterkaarte en ander konstelasiegidse.

5. Begin om `n sterrekunde dagboek te hou. Dit is pret.

6. Gesels met ander amateurs en sluit by `n sterrekundevereniging aan.

7. Jy sal weet as die tyd reg is vir `n teleskoop. Koop die grootste wat jy kan bekostig.

8. Begrawe jou ego en vrae "dom" vrae.

9 . Ontspan en geniet dit.
