Subject:	SGP/MFRSR/E13 - Shadowband misalignment
DataStreams:	sgpmfrsrE13.a0, sgpmfrsrE13.b1, sgpmfrsrlangleyE13.c1, sgpmfrsrlangplotE13.c1
Description:	The E13 MFRSR developed a shading problem on or about 05/04. (The exact date when this problem started is difficult to pin down exactly.) The shading problem is easy to identify on a clear day because plots of direct beam and diffuse irradiance versus time become "fuzzy". The total irradiance is not affected. In response to the shading problem, a whole sequence of events then ensued: these actions were designed to solve the shading problem but did not succeed until the very end. Here's a rundown of what took place: 98/05/11 - shadowband adjustment was made at 1544 GMT - this adjustment corrected the shading problem that occurred in the morning, but inadvertently caused a PM shading problem 98/05/20 - shadowband adjustment at 1804 GMT 98/05/21 - shadowband adjustment at 1630 GMT 98/06/01 - shadowband adjustment at 1910 GMT 98/06/02 - shadowband adjustmnet at 1550 GMT Alas, these adjustments did not solve the shading problem and it seemed to get worse (for example, on 06/11 the shading is VERY BAD from sunup until about 1500 LST). 98/06/16 - shadowband adjustment at 1715 GMT This final adjustment seems to a solved the problem!
