Shift L2521. Start at 167:12:00 GMT = 08:00am 16 Jun EDT End 10:00am 16 Jun SOT Lead DAS (Times will be given in GMT on day 167.) PLAN ---- Continue running load JUN1206A. Do cti measurements surrounding perigee passage. Next orbit will do obsid 7145, an ACIS-S observation of NGC1493 as part of a study of nuclear star clusters in very-late-type spiral galaxies. Then do obsid 6649, an ACIS-S observation of the quiescent neutron star 1H1905+000 to constrain the equation of state via detection or upper limit to the X-ray emission.

EPH temp: 96.12 degF EPH 27V: 17.20 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day, no issues. The JUN1906B loads were approved and signed by the flight director. JUN2606 products are in work for release next week. Expect to uplink the monthly empheris update at the next pass today. ACE solar proton fluxes remain at background levels. The sun is extremely quiet with no significant activity expected. The FD CCB approved the OFLS patch 11.5.3 to correct the OBC patch command generation bug. Expect to install it today.
