Only two very short segments have yet been uploaded, from the original lecture on positional astronomy, given on the 4th of June.

Segments of the lecture, dealing with a celebration of positional astronomy at the Jantar Mantar Observatory, Delhi, are uploaded below, in very small segments. An attempt is being made, to make these segments added together, give a complete perspective of the observatory, while also teaching some basic positional astronomy. Aspects of the working of each and every part of the observatory instruments will be uploaded here.

Video from the observatory location, as well as actual student observations being taken, will also be uploaded here, soon.

Only two very short segments have yet been uploaded. We are attempting to redo the remaining segments with superwebcam, so that the powerpoint presentation can be uploaded in higher quality. This will take sometime and further updates will be mailed after completing the entire lecture and also after the preliminary preparations for Monday;s lecture are completed.
