T-4 minutes from launch as the last hurdles (concerns for toxic vapors over populated areas) are cleared

We're still a long way from that yet. blink.gif The launch has gone well so far, waiting info on whether the spacecraft have seperated from each other and solar panel deployment.

Watching the live stream here, and people are clapping and smiling, so I presume things are going well.

http://secchi.nrl.navy.mil/index.php?p=DataAnalysisOverview

SECCHI has an open data policy. Calibrated data will be made public via the Internet within hours of its receipt. The SECCHI team will provide modern data visualization tools to display the information from one telescope, to overlay data from multiple instruments, and to visualize coincident data from both spacecraft.

And a little more info on some of the instruments:

http://secchi.nrl.navy.mil/index.php?p=Specifics

Coronographs: COR2 will image the corona with five times the spatial resolution and three times the temporal resolution of LASCO/C3.

Extreme Ultraviolet Imager: EUVI provides full Sun coverage with twice the spatial resolution and dramatically improved cadence over EIT.

Afternoon all,

I've managed to catch the X-Band signals from both of the Stereo satellites this morning, the signal was extreamly strong which isnt too suprising as they are so close to earth. I could see sidebands on the X-band signal, presumably downlink telemetry. The satellites only peaked at 15 degrees elevation this morning, so half of the dish was blocked by local buildings. Tommorows pass looks better with a 21deg peak elevation.

I've put up a report of the x-band reception at http://www.uhf-satcom.com/stereo/

regards,

Paul

Are there any stereo websites that uh, don't suck? Just finding a basic rundown of instrument parameters for something like SECCHI/EUVI is like pulling teeth. I hope that once things get going there's a revamp and consolidation of mission information on ONE website.

Yeah but that's what I mean. I visited all those sites and most of them point to the NRL site for information on instruments but even after poking around that (positively byzantine) site for a while I still don't even know how big secchi's ccd is sad.gif

The SECCHI HI instruments have a 2kx2k CCD (page 5) with 2x2 binning.

Shameless plug - I found this using my Google Space Flight Customised Search just by searching for "SECCHI CCD .pdf". It's the first link.

no updates in this topic since october, but actually, very interesting things had happened last week:

QUOTE
December 4, 2006: The SECCHI team opened the doors to the SECCHI SCIP-A instruments and took a few first-light images. Everything went absolutely smoothly. The three doors opened without incident. The first images look great even though they were sent down highly compressed to keep the downlink time reasonable.
The EUVI was opened first and an image from each of the four quadrants looked fine - no major tears or pinholes in the front filters. The sun is close to being in the center of the CCD, and the resolution is beautiful.
Then we opened COR2 and took an image--also beautiful, although there is a slight offpoint (which we expected). The exposure time is just about where we expected, about 3-4 seconds. We then took a pB sequence of 3 images with the result that streamers could be seen all the way to the edge of the field.
Then COR1 was opened and it was also as expected. A pB sequence shows the inner corona nicely out to about 2.5 R, which is what we expected.

(and even more news at http://stereo-ssc.nascom.nasa.gov/new.shtml)

so i am eager to see new pics, especially ones from December 7, when enourmous solar flare had been taken place.

PS First lunar swinby is scheduled for December 15.

The website here doesn't seem to have been updated since launch nearly 2 months ago http://stereo.jhuapl.edu/ The site you posted is the only source of information.
