PASS Support-UTC BOT EOT ---Station------ Local Time ----------------- ------------ --- --- ---------------- ---------- 141/1010-1225 1110 1210 DSS-24 GOLDSTONE 0710-0810 EDT MP: The MAY24 load was approved yesterday. The MAY31 products should be released on Monday or Tuesday. S/C: We successfully completed CAP 1151 yesterday. We now have SCS120 activated, looking for momentum dumps and set to cut them off automatically at 400 sec. We'll be executing preapproved CAPs 750 D, E, F to dump checksum memory in the next couple of days. SIGNIFICANT SOLAR ACTIVITY: At midnight there was 1 spotted region on the visible solar disk. Also, a dark magnetic filament is bisecting the sun's northeastern quadrant. Filaments like this can grow unstable and erupt, producing a type of spotless "Hyder flare." If that happens now, Earth would likely feel some effects from the blast because the filament is turning to face us. GOES X-ray flux: Very quiet. Earth-directed CMEs in the past two days: none.
