YALO Telescope Observer's Report for 2001 Jun 18 Observer: Juan Espinoza Observed all night from 22:45 to 10:00 UTC. Conditions were Photometric most of the night. Problems were encountered, see the summary for details. Seeing and Weather: Beg: Seeing 2.0 arcsec, Clear, Winds Light & Variable Mid: Seeing 2.6 arcsec, Clear, Winds Light & Variable End: Seeing 2.0 arcsec, Clear, Winds Calm Observing Summary: Program mostly completed - Because of extremely bad near the end of the night. (above 3''), some Ohio targets were not observed. Cen X-1 landed slightly in the bad part of the chip on CCD. This happened because the pointing was lost, tricking me into believing I was using my usual guiding star. Yale magnitudes: Cen X-1 0.58 (mmm..) 4u1543 1.32 xte1550 7.17 Aql X-1 2.48 That is all from me for this week, cheers juan ------------------------------ Submitted by Juan Espinoza on 2001 Jun 19 [6:50:55]
