Dear CBAers,

Let's try to help Chris with his AE Aqr observation program over the 
next 3 weeks.  See the AAVSO Alert Notice 458 for more info.  Also: 
Chris, feel free to advocate/inform separately in this space for the 

AE Aqr has a very rapid periodic signal (33 s), which few of you can 
resolve; but it also has "flares", particularly prominent in blue 
light... and has a slow orbital wave as well.  We might well want to do 
a very long campaign on AE Aqr this summer, when it's better placed for 
earthbound telescopes.

It's also time to start campaigns on V1084 Her and V795 Her - both good 
bright-star targets - and V503 Cyg.  And some DQ Hers in the south: 
V1223 Sgr, FO Aqr, AO Psc.

I look forward to seeing many of you in Big Bear next week!

AAVSO Special Notice #281

Revised timetable for AE Aqr MAGIC observations
May 15, 2012

Dr. Christopher Mauche, Lawrence Livermore National Laboratory,
has informed us that the timetable of MAGIC observations of the
intermediate polar cataclysmic variable AE Aqr announced in
AAVSO Alert Notice 458 has been revised. Here is the revised
timetable for the dates in May and early June:

2012 May
16, 3:30 - 4:49 UT
17, 3:21 - 4:49
18, 3:17 - 4:49
19, 3:13 - 4:47
20, 3:09 - 3:53
21, 3:06 - 3:49
22, 3:02 - 3:45
23, 2:58 - 3:41
24, 2:54 - 3:37
25, 2:50 - 3:33
26, 2:46 - 3:29
27, 2:42 - 3:25
28, 2:38 - 3:21
29, 2:34 - 3:17
30, 2:25 - 3:13
31, 2:15 - 3:09
2012 June
01, 3:28 - 4:54 UT
02, 3:45 - 4:54

The later dates in June in Alert Notice 458 have not been revised
as of this time.

As mentioned in Alert Notice 458, B-band photometry is requested
during and +/- 1 hour around the times of the MAGIC observations
in order to correlate the multiwavelength observations of this
campaign, and nightly observations thereafter until the end of
June. Visual observations and photometry in other bands are also
welcome. The 122 and 124 on the AAVSO chart for AE Aqr should be
used. Please see Alert Notice 458 for additional details.

Particularly in May, AAVSO observations are crucial because all
but one of the ground-based observatories doing optical
photometry are too far west to observe AE Aqr at this time.

The MAGIC telescope is located at latitude and longitude:
N 28o 45.7245 / W 017o 53.4007

If your observatory is located along or near this latitude,
your observations are even more crucial, and your special
attention would be gratefully appreciated.

Coordinates for AE Aqr: R.A. 20 40 09.16 Dec. -00 52 15.1 (J2000.0)
