Kevin Ty & Armando Lee
Last June 6 , 2010, members of
the Astronomical League of the Philippines (ALP) held
their monthly meeting at the Manila Planetarium at
3:00pm. Members who attended were ALP President
James Kevin Ty , Charito Ty and son Kendrick Cole (KC) Ty,
VP Jett Aguilar, PRO
Armando Lee, Andrew Ian
Chan, Treasurer Henry So and friend Marilene Ng, Tommy Tan, Belen Pabunan, Christopher Louie
Lu , Dennis Buenviaje, Dante Cruz, Rommel Palacpac, Mark Ian Singson, Michael Cruspero,
Crispin Riosa, Kevin Dagunan, Christopher Lee, Nel Lagda
, Desiree del Rosario, Micky Natividad, and new member
John Ray Cabrera.
The meeting started at around
3:30pm with ALP VP Jett Aguilar giving the members some
updates on the Jupiter Impact that Australian amateur
astronomer Anthony Wesley got to image and view live
last June 6, 2010 with our very own ALPer Christopher Go
imaging it as well as confirming the impact! They
were the only 2 amateur astronomers that were able to
document this event!
Afterwards, ALP PRO Armando Lee
lectured about the large scale properties of the Milky
Way galaxy. He lectured about the: 1.
Interstellar extinction; 2. The range in luminosity for
stars in the region of the Sun; 3. Stellar populations.
Again, these are rare topics which are seldom presented
in astro club meetings. He started off by speaking about
atmospheric extinction to explain its relation to the
study of the whole Milky Way galaxy. The previous error
in estimating the size of the Milky Way was explained in
the light of interstellar light extinction in the
galactic disk. Kapteyn’s underestimation and Shapley’s
overestimation of the size of the Milky Way galaxy was
discussed in relation to interstellar light extinction.
ALP VP Jett Aguilar giving the
latest update on the Jupiter Impact last June 3,
ALP PRO Armando Lee gives an
interesting lecture on the large scale properties of
our Milky Way.

This event more or less happened around 7:36pm with the planet Venus
disappearing on the dark limb of the Moon and
reappearing again on the bright limb of the Moon more or
less around 8:16pm. All 3 ALP observing sites at
AstroCamp Observatory, Nasugbu Batangas and Candaba
Pampanga all successfully documented the ingress and
egress of the event. Still and video images of the
Venus Occultation were also presented to the members.
then reminded the members/audience about the
atmospheric extinction (earlier explained in his
lecture) as he showed his video (with GPS time inserted
frames) of the said event.
discussed on the upcoming June 26, 2010 Partial Lunar
Eclipse. The event will start several minutes
earlier when the Moon rise from the ESE horizon. Full details of the event will
be posted in the ALP main page in the days to come.
ALP IDs were also distributed to the members as well.

Palacpac, Rich Pijuan and Babak Parhizkari. ALPers
who wants to participate on this event should contact
ALP President James Kevin Ty for further details
pertaining to this event, Registration fee is
P500. Trophies will be gven to the top 3
