Select Phase for Guide Stars- Not shown here -------------------------------After a visit is on a short term scheduled, we know the time and V3PA angle. We then select the guide stars and reference stars for OSS.

Funding Still not determined. US Senate CSJ subcommittee funds JWST

at the funding level needed for the 2018 launch date. Assuming this is preserved in the final vote, the final budget will need to be

decided at the House-Senate conference.

Several expressions of support. Most recently 1400 European Astronomers sent a letter to the head of the OSTP, Holdren. Professional societies with membership exceeding 85,000 have also expressed support.

A lot of misinformation (or disinformation) on the web. To help solve this there will be a webinar on Wednesday 21th at 2pm. Speakers: Matt M., Rick Howard and Eric Smith (HQ), John Mather, Julianne Dalcanton and Roberto Abraham.

SWG at STScI

There will be a SWG Meeting at STScI on Sept 20th and 21st. Agenda still being prepared.
