This image is an experiment I did using data from the GONG h-alpha network. I wanted to show the development of some solar filaments that I also imaged myself in July last year and that showed a very nice development in the days they were visible. I gathered data from the period from 4th of …
Some images of the last 2 days of the sun. There was a huge filament coming over the solar limb that made a lift-off in the late afternoon of August 4th. It was cloudy here, but just before the sun was setting behind the house the clouds cleared and I was able to capture the …

Already over a month ago we could enjoy the Mercury transit over the Sun. Yesterday I looked into the SDO satellite data archive to look at some images of the transit (which are great) and decided to use one of the images which was taken almost at the same time as my own image of …
Today was one of the rare occasions that Northern lights were visible from the Southern part of the Netherlands. I went into the polder to a dark place to see if I could catch a glimpse of it. I was nicely surprised 🙂 Camera: Canon EOS40D with 18-200 Tamron zoomlens @ 18mm F3.5 10sec …
The sun as imaged in H-alpha on 08/09/2014. Telescope: TMB-92SS Camera: DMK21-618 H-alpha: Lunt LS75
Here are some images and an animation taken on the 8th of July 2013 using my Lunt-60 solar telescope and Robtics ED110 with Herschel prism or Lunt 75mm etalon. Finally here is an animation showing about 100 minutes of solar activity:
