Ed P. Mark L. 7/20/15- VERY HOT AGAIN TODAY The reduced size and somewhat new crew finished moving lights, generators and support equipment to the next section to begin cleaning. We also had some cord repair to do. We changed out the U-ground style cords on the vacuum machines for a twist lock style plug. Additionally we made some 250' long AWG #10 S. O. cords with twist lock ends and installed strain relief at the generator. 33.5 meters of tube cleaned ending 14.5 meters east of HSW-2-069. 7/21/15 Ed P. Mark L. The temperature has dropped slightly and is supposed to continue a cooling trend for the next couple of days, this makes being in the enclosure much more bearable. The crew cleaned 67 meter of tube today ending at HSW-2-065. We relocated the generator and cords. The new cords are working very well. Rodney is scheduled to return on 7/22/15. The crew will then be back to a full compliment of personnel.
