MPC.get_observations() missing some MPC observations

[emilywhittaker1]

I noticed that astroquery.mpc.MPC.get_observations() is in general only returning some of the observations that are listed for an object with a preliminary designation at the Minor Planet Center website's database search feature: https://minorplanetcenter.net/db_search. For example,

obstable = MPC.get_observations('2010 EA50', id_type='asteroid designation', cache=False)
len(obstable)
12

So get_observations() is returning 12 observations, whereas the MPC gives 187 observations. The missing observations do not seem to be in any chronological order.
