1.  2 March 2022.  11:58 UT (Pre-sunrise)

Northbound pass.  Maximum elevation of pass 5 2 degrees, azimuth74 
degrees.  Sun elevation   -17 degrees.

Flare interval ~11:57:43 UT – Not observed.  Max magnitude  ~3 to 3.5.
Maximum flare ~ 11:58:09 (+/- 5 seconds) UT.  Az/El:  99/49.5.  RA/Dec:  
18:38.5/+29:21.8

Soon after maximum flare the satellite was obscured by high thin clouds 
so the flare end point was not observed.

2.      3 March 2022.  01:23 UT (Post sunset)

Southbound pass.  Maximum elevation of pass 64 degrees, azimuth 285 
degrees.

Flare interval not timed due to bright sky.  Max magnitude ~-0.5.   Sun 
elevation   -6.7 degrees.

Maximum flare ~ 1:23:25 UT.  Az/El:  247/57.7.  RA/Dec:  2:59.3/+21:40


3.     3 March 2022.  12:15 UT (Pre-sunrise)

Northbound pass.  Maximum elevation of pass 84 degrees, azimuth 77 
degrees.

Flare first observed at 12:14:51 UT.  Flare end at 12:16:34 UT

Maximum flare ~ 12:15:41 UT.  Az/El:  138.9/77.6.  RA/Dec:  
16:39.8/+29:15.9
Magnitude ~ -0.5

Faintest star 4.5 to 5.  This was the best pass/flare observed so far 
primarily because I caught the initial flare brightening early in the 
process.  It also may have been the brightest.

All observations naked eye (with glasses).
