TREE STUMP-LIKE OBJECT SEEN ON MSL SOL 1647. We are not yet ready to declare that the object on Figure 1 is really a tree stump, although it certainly looks like one. Care is needed because sometimes in a geological process molten material may rise to the surface, be denser than the surrounding surface material, cool and remain while surrounding material erodes away. When this occurs what remains may resemble a tree stump, but not be one. However there are two items in conjunction with the MSL Sol 1647 anomaly that are worthy of discussion. First, in looking at the track of the Curiosity rover it can be seen that the rover went about 10 meters further east the next sol, but then turned around and went back to the area in question. We may assume that it reexamined the object from another angle, but we don't see the images of it then. We need to see them, and know if there was any attempt made to examine the geological property of the object. Second, at about this time ground temperature reports from the REMS Team went berserk. MSL was in its summer season for MSL Year 3 at Sol 1647. During MSL Years 1 and 2 the coldest ground temperature seen was -87° C. But look at an extract from our record of REMS Team daily weather reports for MSL Sols 1643 to 1650. The night time air temperatures (Column F) are consistent with each other with variation from -73° C to -75°, but the ground temperatures (1.5 meters lower) vary radically (see Column J) with variation from -78° C to -110°.
