Comments: 

- DIMM seeing reached 2.8", so, at 04:15 UT astronomers requested to observe only the brightest stars of the (updated) list and double their exposures times.
- For Alpha Cen B did 35 integrations.  
 - Last (25') integration on G2K001290 (a bad choice? It have a bright companion ES of it as shown in CDS charts) ended with the Sun at -9.8 degrees of altitude.
