Space Weather Flow Chart

I made a Space Weather Flow Chart which provides an oversight on solar phenomenon, solar activity, effect and consequence.

Versie 2 van Onze Zon : De meest nabije ster

De afgelopen maanden noteerde ik alles wat maar enigzins te maken had met de zon. Dit met de bedoeling om mijn eerste versie van mijn paper "Onze Zon : De meest nabije ster" aan te passen en af te stemmen op deze nieuwe informatie. Mijn Kerstverlof was er dus aan voor de moeite maar heeft wel geleid tot een nieuwe tweede versie van mijn paper.
Je kunt het werk hier downloaden en ik wens iedereen veel leesplezier. 

ISS Crossing Disk of the Sun

Tomorrow, Wednesday December 27, around 13h57 (12h57 UT) ISS will be crossing the Disk of the Sun between Antwerp and Liege. This is only visible using a small telescoop with Solar blocking Filters.

Orion Nebula M42

Using a different way of editing my astropictures within CS4 gives some nice results. As an example I used a picture of M42 (Orion Nebula). The technic used results in a complete shift of the histogram and taking out some noise.

Congratulations

Celebrating 5 years of blogging.
