Today ANDE is at about 182 km.
Looking at the plot, at the most one more day is left: http://home.vianetworks.nl/users/hamoen/pa3guo/ande_predict_pa3guo_22dec2007...
But it can be less.
SO DOES ANYONE HAVE SOME UP TO DATE KEPS OR CAN MAKE PREDICTIONS FOR WHEN PASSES ARE FOR THE MID WEST (SOUTHWEST WISCONSIN HE HE HE ) OR EVERYONE TRY TO CAPTURE IT ON VIDEO/ JOE WB9SBD

Actually Joe...I just received your email @ 2200
look out your window...
or look here and add 1-1/2 hour for each westerly pass

Or i wonder how up to date the stuff on heaveans above are? I have passes in en43 on the 23rd of 08:21 and 12:57 cst sound close?

Hi Joe,
During the year I also used Heavens-above, but not during the last days.
I also use NOVA, which uses Celestrack, and it is still very accurate.
For my own antenna tracking SW I use celestrack as well: http://www.celestrak.com/NORAD/elements/amateur.txt
These sets gave today accurate information within 1 minute.
Unfortunately, this site does not include ANDE, NO-61: http://www.amsat.org/amsat-new/tools/predict/
Not sure which SW you use, but the keppler sets are there. Just update them prior to every pass.
Please note though that in the coming hours they will become not accurate anymore. ANDE will dive down very fast. (more doppler, smaller footprint, earlier as the SW predicts)
Success ! Henk

Hi,
I have been getting my Keps from Space-Track.org for the past year or two, since the service came online.
My understanding is that it's the "real" one, and most or all other keps around other web site etc are obtained from there. There are however, restrictions on reuse of the data from Space-Track.
As at right now, the Celestrack keps are set "727" and Space-Track is "729" with a slightly later Epoch time. However, still about 25 hours old.
I've noticed over the last few days that the ANDE Keps have updated multiple times per day, but have stayed some 20 to 26 hours old.
Its possible that this is by intent, for legal or other sensitive operational reasons, given the dramatic rate of change as ANDE is getting lower.
Normally, keps for objects can be only a few hours old when they are updated.
If you look at older copies of the AMSAT Journal, one finds articles about "making" your own Keps, based on the known pass times, as measured over time, and by multiple stations.
I assume that if one had a good model for the drag and other things happening to ANDE, it would be possible to adapt the 24-hours-old Keps, and "tweak out" the minute or so early as reported by some stations.
I imagine that Bob's students could make rather a nice project of collecting every Keps update, and all the telemetry, and feed it into various models to see what can be discovered.
Nothing really new here; just saying ...
As I write this, http://www.findu.com/cgi-bin/pcsat.cgi still shows telemetry just 30 minutes ago, but NOVA is now showing ANDE is ranging between 177 Kms and 195 Kms around the orbits. Even if the weather is fine up at 195, it must be getting windy down at 177, so at some point soon, it will be all too late.
Thanks ANDE, its been fun these last few days.
Regards, Jim, ZL1TYF

Hi All,,
I just ran Satscape, and it spat out the following data.
I'm located northwest of madison WI. -90 long and roughly 43.3 north, 9rough can give more accurate if needed.
satscape did a kep up date,
so do these numbers look good?

Hi,
For the pass just now, 23-dec-2007, 07:40 UTC, multiple stations here in New Zealand sent packets via ANDE.
I decoded 13 packets per below, and heard a few others. I expect most or all of those other stations also captured some too, and maybe some I don't have.
Yay ANDE! - still operational at some 190 Km, per Nova and Space-Track keps.
Unlike other passes, I attempted to track my antenna very close to what was predicted by the program, and it seems to work better than leading as I had been on other passes.
Regards, Jim, ZL1TYF
First packet about 07:38 UTC, and last about 07:42, give or take a minute.
