Finally a good image showing the Great Red Spot! It has been hiding on the back side in all previous attempts, and last year it was quite pale. Here it is seen in nice colour. Image shot at 22:34 UT 19. Feb 2003. C8 + 3x barlow + ToUcam 740. |

After a long period (1 year!) of bad seeing, a new opportunity came. This image was shot 18. Feb. 2003, 20:49 UT, and it shows the silhouette of Io in front of Jupiter. Io's shadow is seen in transit across the surface, and Europ is seen at lower left. Lots of cloud details!! C8 + 3x barlow + ToUcam 740. |

February 10, 2002. C8, 3x barlow, Philips Vesta 675 webcam. Temp +2C. The first night in weeks with imaging options, but the clouds destroyed the session after about 25 minutes, and the conditions were generally poor. The image shows Europa in shadow transit. Processing was done with IRIS using compute_trichro1 command. |

Removed, see above | January 06, 2002. C8, 3x barlow, Philips Vesta 675 webcam. This is an MPEG video (383.13 KB) showing the rotation of Jupiter from 20:43 UT to 22:17 UT. The sky was steady but very far from transparent, -5C. Can be presented in Windows Media Player, but if you want to reduce the speed, I recommend IrfanView |

December 12, 2001. C8, 3x barlow, Philips Vesta 675 webcam. This image has been stacked from 22 frames selected from a 123 frame AVI.
