As ek so na die weerfoto op Kobus Botha se webtuiste kyk (15:30 - Saterdag) gaan die wolke vanaand weer die wenner wees. (Loer gerus hier na die infrarooifoto). En vanaand is die maan so vanaf 21:30 op sy pos. Dit kan net beter word met die maan wat aan die taan is.Maar ek is seker die lekker oop donker aande is op pad. So saam met die Volksblad-kunstefees.Die ouens wat lanklaas `n komeet gesien kan gerus hulle verkykers en klein teleskope uithaal en na C/2008 Q3 (Garradd) gaan soek. Die komeet is op my Nr 1 "Wanted"-lys om die winter se waarnemings mee te begin. Laat weet as julle hom sien.Die foto regs bo, is deur Michael Mattiazzo geneem.Kliek hier vir sy webtuisteHier is `n klompie inligting om dié komeet op te spoor:(Almal Pdf-formaat - Lees met Acrobat-leser.)

GOOD-BYE SUNSPOT 1024: The biggest, most active sunspot in two years is about to disappear. Sunspot 1024 is approaching the sun's western limb and, later today, it will go around the bend. Pavol Rapavy sends this photo from Rimavska Sobota, Slovakia.Readers with solar telescopes should train their optics on the edge of the sun. Even minor eruptions from sunspot 1024 could hurl photogenic blobs of hot plasma high over the limb where they would shine in beautiful relief against the black of space beyond. The parting shots could be the best of all. Besoek www.spaceweather.com vir meer inligting en nog foto's Posted by

Waarskuwing: Moenie met jou blote oog na die son kyk nie. Ook nie met `n verkyker of teleskoop wat nie met die nodige sonfilters toegerus is nie!Gaan loer op die veilige manier na hierdie sonvlek by www.spaceweather.com of kliek hierInligting verkry van Spaceweather.com:SUDDEN SUNSPOT: What a difference 48 hours can make. Only two days ago the sun was blank and calm, displaying the sort of unrelenting quiet we've come to expect from the deepest solar minimum in a century. Then, with startling rapidity, sunspot 1024 burst onto the scene: movie. Unlike other recent "sun-specks", this active region is a full-fledged sunspot group with more than a dozen planet-sized dark cores, crackling with B- and C-class solar flares. "Sunspot 1024 is putting on a spectacular show," says amateur astronomer David Tyler of Buckinghamshire UK, who caught it in mid-flare on July 5th.

In a recent article in the journal Nature, March 28, 1996 vol. 380, page 323, Dr.s A.D. Taylor, W. J. Baggaley and D. I. Street at the University of Adelaide in Australia discuss the results of their 1 year radar monitoring of incoming meteors. When meteorites slam into the atmosphere, they produce ionization in the atmosphere. Radar echos from this momentary ionization allow the velocity, altitude and distance to be determined if you have two or more such installations for triangulation. The AMOR radar in New Zealand was used for a year in this fashion to detect 350,000 faint echos from very small meteorites with sizes between 10 - 100 microns. This works out to nearly 1000 every day, just from this site alone! Over 1508 of these meteorites ( 0.9 percent) were found to be traveling at speeds up to several hundred kilometers per second! On any given day, the estimates are than the Earth intercepts about 19,000 meteorites weighing over 3.5 ounces, every year of which fewer than 10 are ever recovered. About 2800 meteorites are in museums from previous 'falls' and are chemically found to represent about 20 or so distinct parent-bodies. The Earth acquires about 100 tons per day of dust-sized micro- meteoroids.
