Had to redo #59,60 -- telescope stopped

Dome not properly following telescope... Hmmm...have to do manually?  Yuck!

Might have vignetting if dome doesn't track properly...

a064-66		BD28d4211	30	1.36	8:02	53	0.180
Now doing dome by hand...

a067-69		1ES 0206+52	400	1.02	8:12	53	0.171	SNR=45
Varying count levels indicates vignetting -- treat as thin clouds in reduction?

Now seems to be working...

2MASS J03221390+0055134 -- skip due to dome issues?  Yes

a073-75		3C120		300	1.39	9:11	53	0.19	SNR=35
Seeing looks worse now.  Dome angle starts at 136...ends 141.

Seeing now about 3.5 arcsec (9.2 pix).  Seeing was good earlier, now terrible.

a080-83		MCG-01-13-025	300	1.52	9:58	53	0.189	SNR=30-40
A CHANGING LOOK OBJECT!  Strong Hbeta profile seen by  1998A&A...333...48 is now gone, and Halpha is weak.

a084-86		2MASS0414	400	1.53	10:24	52	0.189	SNR=30-40
Seeing better again...

a090-92		Mrk79		300	1.22	11:00	51	0.188	SNR=35
Mrk79 has developed strong asymmetry!

a096-98 	NGC3516		300	1.58	11:45	49	0.203	SNR=40+
Is Hbeta broad line gone?!  Halpha BL still there...
Can do better with Ilic galaxy spectral removal?

Twilight...
