Dear Colleagues,
After nine continuous nights of poor observing weather I have gotten
good photometric data last night. Epsilon Aurigae is still near its
brightest.
A summary of this season's (late summer 2007 through last night - 64
nights) data:
V Filter (26 Feb 2008 V= 2.9847)
Max 16 February 2008 V= 2.9826
Min 23 November 2007 V=3.0996
Change = 0.1167
B Filter (26 Feb 2008 B= 3.5407)
Max 12 February 2008 B= 3.5480
Min 03 December 2007 B=3.6864
Change = 0.1384
U Filter (26 Feb 2008 U= 3.6781)
Max 01 November 2007 U= 3.6501
Min 02 December 2007 U=3.8351
Change = 0.1850
The star system's variations seem to have stopped during the past
three weeks. The system has been holding brighter than V= 3.00 since
06 February 2008. Is this the quiet before the storm?
