The comet hover above my neighbors house. The blue plasma tail and the white dust tail is visible.
These days I prepare for a visit to the observatory NOT at La Palma.
Together with the French astronomers we shall study the comet and its tail. |

| Comment : |
This is a later attempt to process the image a bit better.
The film is scanned at 2400 DPI and with 16 bit depth each channel.
The big problem is to get rid of the background to get the weak details in the tail visible.
Comet discovered 1995-07-23, then it was outside Jupiter's orbit.
Earth closest approach 1997-03-22, 1.315 AU.
1AU (Astronomical Unit, distance Earth-Sun)=150million kilometers.
The blue tail is the plasma tail and the white is the dust tail.
The blue tail is always pointing in the direction out from the Sun.
Only one year after the super bright comet
Hyakutake we got this, comet Hale Bopp with the brightness peaked at magnitude -1 too. |

NOT, Nordic Optical Telescope and Hale Bopp.
To the left the Pleiades.
My view of the comet from 2'200 meters above sea.
One of few moments when we had a clear sky. |
