Hi, wonder if someone could answer a question about Guide 9.0. I installed Guide 9.0 on my PC and the software works fine, but I notice that if I try to...
You would be well served if you would download the MPECsort application file for Guide8 and 9 on the Arkansas Sky Observatories website; this freeware allows...
Motion is along a straight line (as far as I could tell with an approximate manual alignment of the images on what looks like a sunspot above/to the left of...
Some further information on the subject The camera was a Canon 10D mounted to a Meade ETX 90 and a Thousand Oaks solar filter. All images- 1/60 400iso and were...
My guess is a helium balloon. It moved significantly in 8 seconds, so its not a sunspot. But it is too slow to be an airplane or satellite. And it seems to...
Agreed: balloon. Would not be the 1st time. It's definitely not a sunspot. --Rob ... From: mpml@yahoogroups.com on behalf of Tony Dunn Sent: Sat 5/26/2012...
I posted the images on this group, I am leaning towards the balloon theory but the object seems large. It also seems to be moving too fast to be a NEO,...

... Have you attempted to measure the angular size of the object, and then compute the linear size as a function of distance to aid in deciding on a cause?...
I was away the last two weeks and so didn't keep close track of things going on here. I hope that among the "hot topics" was the flyby of 2012 KP24 this...
Brian's post prompted me to shoot a few images of 2012 KP24 (thanks Brian). 16 five second exposures with 15 seconds between each image. Fun to watch as the...
Excellent 2:58 video of the asteroid apparently tumbling through space as it passes near the Earth. Cross post from Tangra group. Terry - W6LMJ - 14.287 ...
Another possibility to observe an NEO crossing the sun? On May 29 about 10:10 UT, the minimum geocentric elongation from the center of the sun will be 0.1...
Dear All We just updated the blog with some info and our follow-up image and animation of 2012 KT42: http://bit.ly/KyzZiU Ciao, Ernesto Guido, Nick Howes and...
Hello all! I can confirm what rotation periods of 2012 KP24 is 0.0416679h +/- 0.00003 by measurements from ISON-NM. Amplitude about 1m. Regards, Leonid Elenin,...
I think the interesting thing is that the amplitude is significantly different for different observers. Depending on the phase angles involved and quality of...
The transit will occur at the zenith in Egypt, with a duration of 12 minutes. Since the apparent size could be half that of a Mercury transit, the object may...
Ignore my comment about observing the transit. As Aldo points out, the size will be 0.006", not 6"... Andrew...

... That's even larger than Apophis will be on 2029 April 13, yet this object is almost two orders of magnitude smaller than Apophis, which means it would have...
Hi all, I'm trying to plot a chart to see this asteroid visually tonight. I used JPL Horizons elements on the ephemerides page for 2012 KT42 and input them...
I'm tracking 2012 KT42 and for those who might be looking for it it appears to be running about 2 minutes ahead of its predicted position. patrick 718...
How did the figure of 6 arc sec diameter get derived for a 5m diameter asteroid? At the time of the transit, the geocentric distance is about .0008AU, or about...
When it finally cleared my horizon 2012KT42 was moving quickly and accelerating fast. Add to that the predicted positions being off a bit and 2012KT42.JPG was...
Hi All, The asteroid 2012 KT42 has experienced a partial eclipse while approaching Earth. I think this is the first case ever of an approaching asteroid...
... Pasquale, I seem to remember the tracking of 2008 Tc3 of which you posted on 2009, entered the Earth's umbra before impact.I seem to remeber this was the ...
Hi Tony, Yes, 2008 TC3 entered the Earth's umbra and then impacted. The case of 2012 TK42 it's a first in having both an eclipse and a transit during the same...
