Hello technogecko-ga,

You can view charts of observations of Delta Cephei for the last 30
days in two formats.

You can generate a light curve by searching for Designation 2225+57 or
Name Delta Cep from Start Date 2452672 to End Date 2452701 (which
corresponds to the dates February 1 to March 2, 2003) on this page:

"Light Curve Generator"
The American Association of Variable Star Observers (AAVSO)
http://www.aavso.org/adata/curvegenerator.shtml

Or you can look at the observations for the past 30 days (and
earlier), by searching for 2225+57 or Delta Cep on this page:

"Quick Look Data"
AAVSO
http://www.aavso.org/ql/

In arriving at this answer, I also consulted the following pages:

"AAVSO Chart: Delta Cep (Cephei)"
AAVSO
http://www.aavso.org/charts/standard/CEP/DELTA_CEP/DELTACEP-A.GIF

"2003 Julian Day Calendar"
AAVSO
http://www.aavso.org/cdata/jd2003.pdf

I hope that this information is helpful.

WhatI am looking for is the actual values for present tense. IE data
from the past current 30 days, more specifically in text format not
graphical. ie:

3/1 - Magnitude -3.2
3/2 - Magnitude -3.4
.. and so on

The "Quick Look Data" has this information.  There is a column of
observed magnitudes: for example, for Mar. 1, there was an observation
of 3.5 magnitude.

By the way, instead of searching on the Quick Look Data page, you can
use the following link:

"Quick Look data for DELTA CEP"
AAVSO
http://www.aavso.org/cgi-bin/quickquick.pl?star=DELTA%20CEP
