"Plettstone 1999" Super Nova at Fiddletown

by Rashad Al-Mansour


On Friday November 5th. I left San Francisco for the California Gold Country and my New Moon observing site outside the sleepy hollow called Fiddletown. The drive was pleasant although there was more traffic than I expected.

I left at 2:00pm and arrived at 5:00pm to be greeted by Dennis Beckley, who had arrived not long before I did. 20 minutes we were later join by a young man named Casey, a friend who happens to work at the Orion store in S.F. who had come to do some astro-photography.

It was dark, or nearly so when I got there so there was little time to relax. I set up my observing equipment and then my tent and finally settled back and had a quick snack.

As darkness came so did the stars. The Summer Milky Way was a washed with stars and I was sure I was going to have a great night of observing. Later in the evening Dennis would remark that it was as dark as he had ever seen it there and was certainly the darkest I had ever seen at Fiddletown. We attributed the darkness to valley fog that must have just blanketed the Tracy/Stockton light dome and subdued the one from Sacramento. This place is always dark, but this night was really dark.

I rarely have a pre-planed observation program laid out when I observe and tonight was no exception, I usually let the sky conditions dictate what I choose to go after. On this occasion any program other than Double Stars would have been a winner. The transparency was excellent, and the seeing varied from fair to fairly good. At one point I was able to see the E and F stars in the Trapezium

There were several highlight during the evening, I resolved a 14.5 mag central star in a planetary, sorry I forgot the NGC #, several of the Hickson galaxies 15 + Mag. But the best, was the observation of "Plettstone 1999" the Super Nova in NGC1637, discovered by our own Michelle Stone. It was a fabulous sight. The brightness of the Nova was striking. Both David and I were confused as to which bright knot was the galactic core. After looking at a photo from the digital sky survey we were able tell. Congratulations again Michelle! Can't wait to get out to your place and see how you did it.

By 4:00am Venus had clear the trees in the East and it's brightness ruined my hunt for those faint fuzzies so at that point I turned in for some much needed sleep. Needless to say I had a great Friday night.

I had planned on staying two nights. And was hopeful that it would happen until about 3:00pm. I looked southward and to my dismay there was a large band of thick clouds coming my way. Not taking any chances and counting my blessings from the night before, I packed up my things. As I was packing Ray Cash drove up hoping to do some imaging. And as I drove down Fiddletown road headed home, I spotted Steve Gottlieb headed for the observing site. I hope they had partial success after such a long drive.

Below is a partial list of the night's observations
