Further observations a few hours later also showed V4641 Sgr back at normal
brightness

SGRV4641       100910.439   124  Stu.RASNZ
SGRV4641       100910.443   127  Stu.RASNZ
SGRV4641       100910.449   127  Stu.RASNZ
SGRV4641       100910.451   126  Stu.RASNZ
SGRV4641       100910.453   127  Stu.RASNZ
SGRV4641       100910.458   124  Stu.RASNZ
SGRV4641       100910.460   125  Stu.RASNZ
SGRV4641       100910.551   133  Stu.RASNZ
SGRV4641       100910.557   133  Stu.RASNZ
SGRV4641       100910.563   133  Stu.RASNZ
SGRV4641       100910.578   133  Stu.RASNZ
SGRV4641       100910.594   133  Stu.RASNZ

The time below was a typing error

should have been 100910.460 as above.
