Specific Time: Y

Start: 58578.900
End: 58583.900
Remarks: see box below on coordinated observation for better explanation of time ranges. This is just to specify relevant dates. "Urgency" of "next day" entered above on justification is worst case for achieving simultaneity. The optimal time estimates from the South African observers cover April 5-10.

ToO: Y
Coordinate Observation: Y

Observatory: SOUTH AFRICA LARGE TELESCOPE (SALT)
Description: This is the second attempt at achieving simultaneity with the South African optical observers. Optical observers will be trying to observe within time windows of 2012 to 2126 April 5 or 0216 to 0330 April 6. For each additional night afteer April 5-6, shift UT times earlier by about 4 minutes per day, up to Apr 10 . (This time V834 Cen and VV Pup are equal priority -- whatever's best for NICER)

Uninterrupted: N

Justification:

Estimated Count Rate (cts s-1): 1.000
