Bernhards Comet Project

Bernhard's Comet and Asteroid Project (MPC code: B82 Maidbronn)

Welcome Surfers from all over the world

The private Comet Project is open for all lovers of comets. I invite all comet and asteroid photographers, both amateurs and professionals to take part in this project.
We are publishing our images, analysis, actual news and share our love to comets and asteroids.

News: periodical comets, non-periodical comets

Hearty Welcome, friends of comets and minor planets!

We are living on a smart planet, surrounded in space by its big and small brothers and sisters since unimaginable times.
This web is an independant approach to the great show in our neighborhood in space with amateur skills.

The comet has a magnitude better than 8 now, so everybody is invited to observe it with binoculars.
Michael Mattiazzo is predicting an "edge-on" view to the comet at its best visibility. --> Yohoo Comet images Group message

Meanwhile from our Earth perspective, the direction of the main tail changed to the "other" side of the comet. Image at April, 12 (April, 13 2009)

Blinking a series of 60 images (total 180min.) of comet 116P/Wild at Febr.,15 2009,
I found three asteroids, two of them are already known, one was seemingly a new object: K09C45D or 2009 CD45.
On Febr.,19 I could find the "new" object again on this image of comet 116P/Wild.

detected by Spacewatch at January, 31 2009.
Indeed I found two different objects, not a single one. They had a similiar position, so I could easlily mismatch them. (March, 7 2009)
