I'm continuing to monitor Lemmon's fantastic Oppy weather page and I noticed something: the table of sols/opacity near the bottom of the page lists a couple of sols recently where tau dropped below 0.6, namely 2859 and 2861 - on both sols the table gives tau = 0.59. But the graph for MY31 doesn't drop below 0.6 for many sols. Perhaps this is just a matter of resolution on the plot?

... Indicates that the Mössbauer integration on Amboy began February 1st. Will be interesting to see when it stops! |

Whenever we get upwards of 100-something hours on it! Will take a while. She's an old bird.
What else has been going on in here? Winter ops and MSL have slowed down my shift work with Oppy... -m |

A quirk in the opacity page is that the data happen to get into it via two separate paths, just due to hysteresis. The plot shows individual data points, but they are filtered to only include mid-sol data (excluding, for instance, calibration data taken with a low Sun). The table shows data used in operations, which happens to be a sol-average that is more inclusive. The two are usually identical. On sols with calibration points (or for a recent sol, no mid-sol value), they diverge. The variation should be slight, but the low values in the table are due to the fact that the calibration values are systematically lower and indicating that tau will come down with the recalibration. I'll say more about that in a few days.

New fanciful "nowhere near accurate scientifically, just a pretty picture" view of sunset at Endeavour Crater...

I took my time with that gorgeous Sol 2847 sunset view, here is my version. (Also an experiment in linking to a Facebook album.)

Beautiful job, Don!

Great job Don!
What a Marvelous Pancam sequence that turned out to be. Thanks to the whole MER team for making that possible. |

... Oppy weather page... I just delivered recalibrated data for the next PDS release. Including the more recent data, the tau values look about the same at Ls=0 and fall back into line with previous years by Ls=30. All in all, MY31 so far looks quite like MY27, with tau now ~0.54. The dust coming out of the sky will mean more is modeled on the arrays, since power production is a known. I'm not sure when the update will go live; since it affects other systems, it must be done carefully. |

While the panorama fills in... here is a little dune with an interesting rock formation off to the right.
To this old beach bum, it reminded me of rotten planking of a long ago and forgotten schooner sticking out of the dunes of Cape Cod. This was an L456, but the picture look really blue, so I adjusted it... EDIT: The old 'figure-ground' perception paradox. What looked like an upraised rock (at first) is actually a falling away down-slope. The dirt is darker (more in shadow, its falling away). The bright apex near the darkest materials is a 'cape' for lack of a better word. oops! -------------------- CLA CLL

"North Pole"... ( )
Larger version on my blog at: http://roadtoendeavour.wordpress.com/2012/...ere-for-a-while ...where I ask Steve Squyres about plans for Oppy... * Can you give us some idea of the plans and schedule for driving away from this winter haven? I gather we may be here for another few months - unless a friendly neighbourhood cleaning event gives Oppy a good brush? Yeah, we'll be here for another few months unless we get lucky with the wind. * And then? Head north to check-out the tip of Cape York, or backtrack and look for some more gypsum veins? Or is Solander Point - and the hills of Tribulation - calling from the south? Basically south, I think. We want more gypsum veins, and we'd like to find a contact between the kind of rock we saw at Chester Lake and the kind of rock we saw at Tisdale. And then, of course, there's always the hunt for clays. But I don't think we'll want to prolong our stay at Cape York too much... we've already accomplished a lot here, and there's good stuff farther to the south. We'll see... -------------------- |

... a 'real' ding ... http://qt.exploratorium.edu/mars/opportuni...43P2544R2M1.JPG Around the middle of the image, near the edge between light and shadow, is that a 'real' ding in the LGA? |
