Dear Tohbans I would like to re-point Yohkoh tonight by about 41" N, 5" E. This will be the location of the new NORML PNT command, OG#32. Please upload OP+OG and issue the ROG#32 at any time. The contact times are at night now, so you will be not be able to confirm the motion directly by watching the image move. The details below are just my worksheet for doing the calculation for the new OG contents.
