| Data from the night of July 26/27, 2001. Poor conditions with high to moderate cloud, very humid with some ground fog. No breeze. Typical scathe < 0.02 mag. |  |
| Night of July 31/August 1, 2001. Poor conditions,bright moon and thin cirrus - occasional heavy cloud. Best scatter approx 0.015. WZ Sge is about 0.5 mag fainter than on July 26/27. |
 |
| August 1/2 data. Marginal night punctuated by cloud. Best conditions scatter approx 0.01 mag but worse overall. |  |
| Data from the evening of Aug 2/3, 2001. Generally good conditions punctuated by some cloud. Moon bright. Typical scatter approx 0.01 mag. |
 |
| Data from the evening of Aug 4/5, 2001. Good conditions punctuated by some cloud near end of night. Moon bright. Typical scatter approx 0.015 mag. |  |
| Data from Aug 6/7. Fair conditions punctuated by long, cloudy interval. |  |
| Data from Aug 9/10. Excellent conditions with typical scatter approx 0.008 mag. SH's clearly visible with rich, complex structure. The C2-C1 curve shows signs of variability. WZ Sge continues to fade. |  |
| Very good conditions on Aug 10/11. Haze but very steady seeing. Scatter approx 0.015 typically. SH's continue to be prominent with complex "sub-structure". |  |
| Aug 11/12, 2001. Good conditions, clear with light to moderate breeze. WZ Sge is fading so switched to C2 and C3 as comp and check. |  |
| August 12/13, 2001. Excellent conditions at the start of the night with scatter approx 0.006 mag. High winds during the mid part of the evening have amplified the scatter but SH's are still clearly visible. The system continues to fade. |  |
| Aug 14/15, 2001. Very good conditions. Scatter C3-C2 approx 0.01 mag. System is fading at about 0.1 mag/d but still clearly displays SH's. |  |
| Aug 15/16, 2001. Very good conditions but problems with blooming on comp star in early evening compromised the first hour of data. Over-all, lc still robust with SH's clearly present. Typical scatter 0.015 mag. Ramping at end of evening suggest onset of rapid decline. |  |
| Aug 16/17, 2001. Very good conditions, WZ Sge is now in rapid decline. Some modulation present in lc but SH's are not obvious. Typical scatter approx 0.015 mag. |  |
| Aug 19/20. Some cloud at start of evening but excellent conditions there after. Typical scatter (C4-C3) approx 0.005 mag. WZ Sge very faint, 60 s integrations used. |  |
| Aug 26/27. Generally good conditions from 6h UT - 10h UT. Scatter (C5-C3) approx 0.01 mag. Modulations and eclipses visible in light curve. 60 s integrations. |
 |
| Aug 28/29. Very good conditions, scatter C5-C3 <0.007 mag for most of night. Some thin cloud at the beginning. |  |
| Aug 30/31. Fair - good conditions. WZ Sge is brightening. Typical scatter <0.025 mag. |  |
| Aug 31/Sept1. Very good conditions at start but deteriorating as night proceeded. Terminated by cloud aprox 9h UT. WZ Sge remains bright with low amplitude humps re-appearing. Typical scatter < 0.02 mag. Switched to 40s integrations. |  |
| Sept 2/3. Poor conditions. Clear at start but high cloud and wind later. Typical scatter 0.02 - 0.03 mag. System appears to be going back into decline. 60 s integrations. |  |
| Sept 3/4. Good conditions, some scattered cloud at times. WZ Sge faint at start but underwent a dramatic brightening at approx 5h UT. System brightened 0.7 mag in about 4 hours. Typical scatter for night 0.02 mag. |  |
| Sept 5/6. Very good conditions. WZ Sge remains bright and shows clear, 0.10 mag humps. Scatter typical 0.02 mag. |  |
| Sept 7/8. Clear with occasional breeze. Very good conditions with scatter (C4-C3) approx 0.01 mag for most of the night. WZ Sge fading once again. |  |
| Sept 8/9. Brief data set from a poor night. WZ Sge has faded considerably since the previous night. Typical scatter (C4-C3) approximately 0.03 mag. |  |
| Sept 10/11. Brief data set. Good conditions but rapid deterioration. Secured about 1.5 h of data. Indication of a hump early in the run, otherwise system has continued to fade. |  |
| Sept 13/14. Excellent conditions, scatter (C4-C3) < 0.006 mag. WZ Sge continue to fade but lc shows structure. Correction for contamination from adjacent star is also included in lc. |  |
| Sept 14/15. Very good conditions, warm with light breeze and bright aurora in N during early morning hours. Typical scatter (C4-C3)<0.01 mag. |  |
| Sept 15/16. Excellent conditions, scatter < 0.008 mag. LC shows eclipse signature with variation (corrected) of about 0.2 mag. WZ Sge apears to be in a slow, steady decline. |  |
| Sept 19/20. Bit of cloud at beginning but overall very good photometric conditions. Scatter approx 0.007 mag during the night. WZ Sge appears to have "plateaued". Humps and eclipse features clearly present. |  |
| Sept 20/21. Cloud at times during night. Fair - good conditions with scatter approx 0.015 mag. |  |
| Sept 21/22. Very good conditions, light breeze and some fog at end of night. Typical scatter < 0.013 mag. Amplitude of humps increasing. |  |
| Sept 23/24. Cloudy at start but excellent conditions there after. Typical scatter approx 0.006 mag. WZ Sge showing distinct hump and eclipse features. |  |
| Sept 25/26. Very good conditions at start but high cloud and aurora forced termination around 6.5 h UT. Typical scatter < 0.009 mag. Gradual fading at last? |  |
| Sept 26/27. Very good conditions then cloud at 6.5 h UT. Typical scatter 0.007 mag. |  |
| Oct 1/2. Very good conditions, moon near full and faint aurora in target area at times. Typical scatter 0.006 mag. |  |
| Oct 3/3. Excellent conditions early in evening with rapid termination due to cloud at approx 6.5 h UT. Typical scatter 0.005 mag. |  |
| Oct 4/5. Good conditions, some cloud and moderate breeze. Typical scatter 0.01 mag. Humps fading. |  |
| Oct 5/6. Superb conditions at the start (scatter < 0.004 mag) but cloud began moving through at 4.5h UT. System still showing weak hump activity. |  |
