We kicked off our astrocamp early with some weather satellite data capture sessions which clearly show the clouds that will roll over us at about 2:00AM
Once the Sun went down started observing in earnest, with multiple scopes running.
Early in the night, before the Moon came up, we had magnificent views of the Milky Way
As we watched, Io and its shadow transited across the face of Jupiter. This image shows Io emerging from the disk of Jupiter, with its shadow close by.
Along the way we collected some spectroscopy data for our projects, including spectra of Jupiter and Saturn, we also got some close up views of the Moon and did a spot of Deep Sky nebula hunting.
OK, It’s just a rainbow. A rainbow appears when the light from the Sun is split into its component colours as it passes through water in the Earth’s atmosphere.
A Backyard AstroScience team is currently exploring Spectroscopy using their telescope and a Grating to split the light into its unique spectrum. The next step analyse each of the images using RSPEC to see how much science we can extract.
I used a basic radio scanner and a Quadrafilar Helix antenna (QFH) made from bits and pieces from my local hardware store, to capture this image from the NOAA 19 Weather Satellite as it passed overhead.
WXTOIMG was used to process the radio signal and produce the final image.
Tasmainia shows up clearly in the centre of the image, with Victoria and South Australia above it.
If you play the recording of the satellite transmission, notice how the signal quality changes as the satellite rises above the horizon and finally drops out of sight.
The next challenge is to capure a night-time pass and image the satellite itself as it passes overhead.
NOAA-19 was launched on February 6, 2009 and is the last of the United States National Oceanic and Atmospheric Administration’s POES series of weather satellites.
