Span cylinder at 1250 psi, N2 at 550 --> 1800 psi

at approx 14:30 MST, removed cc40798 (n2) and started cc234071 at 1800 psi

started saving internal logger data every 10 min rather than every 5 min (new programs: prf_04.csi, met_11.csi, nctc_06.csi, soil_04.csi, tc_14.csi)

played a bit more with the photospec computer (still seems to be having problems! left it with the keyboard and mouse unplugged)

swapped radCAM SD card (appears to be working ok)

tried to fix the MBR on the photospec computer; unplugged the USB hub (no keyboard or mouse); it was working when I left
