I’m Robert, an astronomer at the California Institute of Technology working on thePalomar Transient Factory (PTF). I have arrived at the Palomar Observatory in anticipation of my two night run on the 5.1 meter Hale Telescope. The plan is to take spectra of new PTF discoveries to find out what they are, and maybe follow-up on some of the more interesting sources we’ve already identified.

As you can see from the photo, the mountain was dusted with snow a couple days ago, but it was quite nice out at my arrival. Hopefully the wet stuff will help clear up our ash problem left over from this summer’s wild fires. More rain and/or snow may fall in the next few days, but I’m hoping the skies will clear up enough at night so that I can get some observing in.
Our survey telescope, which is just a short walk from the Hale Telescope, has gathered some new images over the last few nights. These likely contain a few new supernovae which you can help us identify. If all goes well, I will make spectroscopic observations the next two nights of the best candidates found. These data will reveal what the candidates are. There’s always the chance of discovering something new, which makes this all very exciting!
So happy hunting, and look for updates throughout my observing run.

I love Mt Palomar, it was the first mountain we visited when we moved to CA from NY …. I have always wanted to visit the Hale Telescope, but I guess helping your fellow galaxy zoo scientist classify our fellow outer-space galaxies from home can help better understand our own existence. Can civilians actually get a tour of Mt. Palomars’ Observatory?
Cool Picture. I wish I could go to see the Hale telescope. My dad told me it’s a really old telescope. I’m hoping to organize some of the Hale telescope’s new pictures.
Thanks
