Describes how SNFactory will measure ~300 type Ia supernovae in the range 0.03 <z <0.08 over the next 3 years.

Would like to know about other similar projects, esp how many supernovae will be measured in this low redshift range before JDEM/SNAP.

For example, where can I find more info on the KAIT/LOTOSS line in Figure 2? I had a look at the KAIT website http://astron.berkeley.edu/~bait/kait_lwd.html but couldn't see this info. Is this an ongoing survey or a past one?

I see the Carnegie Supernova Program http://csp1.lco.cl/~cspuser1/CSP.html should measure in detail >100 type 1a supernovae over the next 5 years. Would be interested in an update on this.

Are there any other similar projects?

Are there any plans to follow up on the ~6000 local supernovae that should be found by GAIA eg. [arxiv]astro-ph/0210570[/arxiv]?

The proposed Dark Energy Survey (DES), a Blanco upgrade, will observe ~1900 SN Ia out to z ~ 0.8, starting in 2009.

Hi Jon, thanks very much indeed for that.
Does anyone know how many SN that will give at low z? ie. 0.03<~z<~0.08?

The SDSS is starting a new SNe project to target SNe in the range 0.05<z<0.35. The predictions estimate ~300 good SNe light curves will be measured and it will run for the next 3 years. Josh Frieman at FNAL is heading it up, but there is a growing european effort to follow these SNe up; contact me if your interested. There is also an effort to find SNe in the SDSS spectra - approximately 100 at z<0.1 have been found this way already (I believe these are public).
