>> Hi,
>>
>>
>> I have made recent observations of V745 Sco in the I band. Preliminary values:
>>
>> 2014 Feb 1.1  13.98 CCD-I
>> 2014 Feb 3.1  13.78 CCD-I
>>
>> Note that these were typical Ic values for the previous season (range 13.5-14.2). If in outburst, it must have started after 3.1 
>> Feb 2014.

>> I'll surely follow this up tonight.

>>> Rod Stubbings just reported an outburst of the recurrent nova V745 Scorpii, at V=9.0.  The sky placement is mighty unfavorable
